997 Turbo eRam Kit™


Don’t risk Power Steering fluid leaks into your engine bay or down the bumper. Extensively designed and engineered to permanently fix the overly complex and troublesome factory hydraulic mechanism.  Since 2015, our eRam Kit™ is the best permanent economical solution for a fully functional wing!  WORKS EXACTLY LIKE THE FACTORY MECHANISM.  Up at 75 MPH, down at 37 MPH or with the switch.

Basic eRAM KIT™ CHOICES (Options/Accessories Below):

  • 4 3/4” [120 mm] eRam Kit™
    Our flagship eRam Kit™ provides SUPERIOR rear downforce, as the wing is up higher in cleaner air – just like the factory GT2, GT3 and GT4 wings. This kit provides excellent rear wheel down force at higher speeds. This eRam Kit™ raises the wing 4 3/4” [120 mm] above the parked position when deployed.  For the 997 Turbo coupe, that’s an additional 3.3” [85 mm] higher than the factory mechanism raised height. Superior aesthetics – you can easily see the wing deploy in the rear view mirror, observers can readily see the raised wing on the street or track.  Many 997 Turbo owners that track their car opt for this eRam Kit™ version.
    Note:  Parked wing is 3/4″ [20 mm] above the rear lid ducktail spoiler as shown:

4 3/4″ [120 mm] eRam Kit™  for the 997 Turbo

4-3/4″ eRam Kit™



  • 4” [100 mm] eRam Kit™
    “Aggressive yet not excessive”.  Provides very good aerodynamic benefit, as the wing is up in cleaner air at speed.  Added benefit to rear wheel down force at higher speed. This eRam Kit™ extends the wing up 4” when deployed – yet sits flush to ducktail when down.  For the 997 Turbo coupe, additional 2.6” [65mm] above factory raised height, for the Cabrio 1.4″ [35 mm] higher. Great aesthetics – you can easily see the raised wing in the rear view mirror, observers readily notice your extended wing on the street or track.  When parked, wing is flush to duck tail like factory system.

4″ eRam Kit™




  • 3” [75 mm] eRam Kit™
    Offers improved aero-effect down force and aesthetics compared with stock factory height. On the 997 Turbo coupe the 3″ eRam Kit™ is 1.6” [40 mm] higher than the stock turbo coupe’s extended wing.  For the Cabrio it’s 0.4″ [10mm] higher. This is also the closest eRam Kit™ to the factory raised height for cabriolet models. The perfect choice for those who want to retain more of a stock look – yet appreciate a bolder rear wing statement. When parked, wing is flush to duck tail like factory system.

3″ eRam Kit™



  • 2” [50 mm] eRam Kit™ (only for 997 Turbo Coupe)
    For those who want an economical choice for replacing a dead factory hydraulic mechanism with all of the eRam Kit™ benefits.  Requires special installation techniques and takes a bit longer to complete. Coupe height is 0.6″ [15mm] taller stock, but Cabrio height is  0.6″ [15mm] shorter than factory height and is NOT recommended. When parked, wing is flush to duck tail like factory system.

2″ eRam Kit™

Recommended for Coupe Only.



eRam Kit™ Options / Accessories / Tools

  • clock_PNG6628SuperFast Version™ Reduces up / down stroke time significantly. The wing travels up or down faster than the factory mechanism.  The 4 3/4″ or 4″ eRam stroke time is reduced from 11 seconds to just over 3 seconds. The 3″ time is under 3 seconds, while the 2″ time is about 2 seconds.  A must for those that track their Turbo.   $99


  • eRam-BootsDust & Moisture Boots Protect your eRam Kit™ investment.  These are a safeguard for keeping the electric rams dry, dust free and looking like new.  When ordered, come pre-installed on your eRam Kit™.  Note; the boots range in color from gray to black. $49


  • RennKit-Wrench-4Pin Wrench:  This tool is for removing the wing from the factory hydraulic rams. A MUST FOR THE 997 TURBO as the factory used a very strong thread locker. Engage the wrench pin through the outer cylinder to grasp the inner slotted washer. Makes the job of removing the wing easy and safe!  Heavy gauge black oxidized steel finish. Imported from Germany. $49

Our patented 997 Turbo eRam Kit™ consists of two pre-assembled self-contained electric rams that simply bolt onto the engine lid with absolutely NO modifications. The eRam Kit™ includes a small electronic “MicroModule Device™” that connects to the factory wiring and prevents the dreaded SPOILER WARNING. Nearly plug and play!

Functions exactly like the factory mechanism; wing extends by using the dash switch or after reaching 75 MPH (100 Km/h). Wing retracts with the dash switch, or upon slowing to 37 MPH (60 Km/h).

Stop spending time, effort and money on the troublesome factory system. Fix one item and there are several more parts that have degraded and will soon fail.  Don’t risk a hydraulic wing system failure and subsequent leak of corrosive (and flammable) Power Steering fluid into your hot engine bay or down the back bumper. The original factory hydraulic mechanism can be rebuilt, but can NEVER be prevented from failing or leaking fluid. Our patented robust all-electric eRam Kit™ can never leak and eRam Kit™ parts are easily removed with standard hand tools for servicing or upgrade.  

The dealer charges up to $4000 to replace the troublesome hydraulic mechanism. Others offer a rebuild service, simply tearing down and repairing the same failure prone mechanism, often using solvents to swell internal o-rings.  Another offers shiny aftermarket parts for the internal hydraulic mechanism made out of stainless instead of brass.  They don’t even attempt to call it a permanent solution, claiming it is “easy” to change out cheap internal o-rings, then refill and bleed the mechanism once it fails again… Who wants to go through that – let alone more than once? It’s only a matter of time until hot engine bay conditions destroy one of many hydraulic components that are failure prone!  14 WAYS THE HYDRAULICS FAIL

The patented eRam Kit™ comes with two self-contained electric eRams, all fittings, fasteners, electrical connections and the tiny MicroModule Device™ which prevents the spoiler warning.  No cutting, drilling or modification to any part of the car.  Easy install – about the same skill level as changing brake pads.  Installation of the eRam Kit™ takes about 2 hours for anyone with any mechanical skill. Most customers install the eRam Kit™ themselves using our  illustrated instruction guide and video (links sent with purchase).  Easily maintained – no special tools needed.  Easily modified – for example to later exchange for different length rams or to add Dust & Moisture Boots.

HEAVY DUTY yet light-weight aluminum electric eRams have built-in limit switches on each eRam.  Greatly reduced risk of failure along with the car’s  relays.

COST EFFECTIVE – Our patented eRam Kit™ is much less costly than a new factory mechanism (up to $4000 installed by the dealer) – and can NEVER leak or fail due to the many problems associated with the OEM hydraulic mechanism, outlined CLICK HERE.

997 Turbo with 3″ Super-Fast eRam Kit™ Installed

Each eRam Kit™  comes fully pre-assembled, all hardware and electrical components included – simply bolt onto the 997 Turbo deck lid and wire up.  Choose from 4 extension heights and various options / accessories to transform and upgrade your 997 Turbo.

    We can provide a custom height for your factory or aftermarket wing, from 2″ all the way up to 6 3/4″!  CONTACT US for options.
    NOTE:  Only 2″, 3″ or 4″ eRam kits sit flush with decklid.

Patented 997 Turbo eRam Kit™ Details


  • The ONLY Patented all-electric turbo wing actuation device.
  • Comes pre-assembled with everything needed:  A set of eRams and MicroModule Device™ spoiler warning prevention electronics.
    (The pin wrench is highly recommended for the 997 Turbo – but not included – available here:  PURCHASE )
  •  Robust – self contained rams are designed for desert duty and have a duty cycle equivalent to stroking every 6.5 minutes for 10 years!
  • Works EXACTLY like the factory system:  Up at 75 MPH, down at 37 MPH, or by using the dash switch to raise and lower.
  • Available in 4 Heights:  2 inch (similar to the coupe), 3 inch (similar to the cabrio), 4 inch and NEW 4-3/4 inch (maximized downforce at high speed).
  • Two Deployment Speeds:  Standard & SuperFast Version™ option.  SuperFast Version™ rams are 4 times faster at deploying the wing up or down.  Faster than the factory mechanism!  Great on the track.
  • Simple Installation – Easily bolts on.  NO MODIFICATIONS to your Turbo (no drilling, machining, filing, etc.) Under two hours start to finish, remove old hydraulic mechanism, bolt on eRams, wire up and attach wing  – it’s that simple. Illustrated step by step instructions and video link sent with purchase.  Our step by step video guides you through the whole process!
  • Light Weight – Saves PRECIOUS WEIGHT at the top and back of the Turbo – 1/3 LIGHTER compared to the OEM hydraulic mechanism.  Note to track guys:  Reduces center of gravity at the very back of the Turbo!
  •  Cost Effective – compared to a new OEM system from Porsche®, this is a far more economical alternative that is nearly half the cost.
  • No Worries – Two year limited warranty – see bottom of PURCHASE page for details.  We are proud of our product and brand – we stand behind it.
  • Upgrade Investment – Car owners that sell their “bone stock” Turbo always list the eRam Kit as a valued upgrade.

Wing operation with the eRam Kit™ installed is identical to the factory system; either by using the dash switch or when driving. Automatically deploys the wing up after reaching 75 MPH (120 km/h) and back down once at 37 MPH (60 km/h).  The motor driven rams are designed for harsh environments and are protected from external moisture with a dual-seal design. Adding the recommended Dust & Moisture Boots  further protects the eRam motor and gearbox from dust, moisture and harsh engine bay conditions.

The Porsche® 997 Turbo owner’s manual states that the Turbo should not be driven without proper wing operation – the car’s aerodynamics were designed around an operational wing:

Calculation of Duty Cycle:

The eRam Kit™ is designed for fairly harsh environmental conditions.  If you used your car as a daily driver 5 days per week, and took 4 trips per day on a highway to cycle the rams 8 times, that equates to 2,000 cycles per year, or on average 0.23 cycles per hr on average.

The eRam Kit™ has a very conservative 25% duty cycle.  Thus, you would be able to safely cycle your wing 300 times per hour.  In effect, there is a 1300:1 safety factor on an already conservative duty cycle.

High Speed Testing

The eRam Kit™ has performed as designed during several high speed track trials over 200 MPH!  Many eRam Kit™ sets have been purchased by owners that track their Turbo.  They prefer the tallest and fastest eRam Kit™, as they want the factory look when down, with the benefit of better rear end down-force at the track.  Wing operation is stable with smooth and precise actuation. Quicker lap times were achieved with the 4″ eRam Kit™ installed. Street or track, operation is exactly the same.
Our 997.2 Turbo with 4.75″ eRam Kit at Road America:

Aftermarket Airbox or Y-pipes?

Please contact us for fitment info if you have aftermarket boost hoses or airbox (Fabspeed, EVOMS, Turbokraft, etc.), generally these are fine with the eRam Kit™.  The Turbokraft airbox will only accommodate the 3″ or 2″ eRam Kit™.  We have a guideline to help you check, download HERE.


For Turbos with a fixed wing (e.g. GT3), aftermarket back lid and integral wing or for a malfunctioning OEM hydaulic mechanism that still works.

  • MicroModule Device™:  Included with every eRam Kit™, this device can be purchased separately to prevent the spoiler warning on any 997 Turbo.  For 997 Turbos with GT2 / GT3 / Aero or after-market integrated lid wing.  Less costly than a new GT2 / GT3 wiring harness!  Stop the spoiler warning for good! $149.99

997 Turbo – OEM Hydraulic WING EXTENDERS™


Extend your OEM hydraulic mechanism’s wing higher by 1″ or 2″.  Another way to get your wing further up in the clean air for better downforce!  In fact, the cabriolet wing raises up higher due to inherent turbulence from the cab top, up or down.

10 minute installation:  Simply use our Pin Wrench to remove the wing.  Screw the wing extenders onto the wing and tighten with the pin wrench, then screw the rams back onto the Wing Extenders with the pin wrench.  DIY simple.  Illustrated step by step instruction link provided.  Combine them to go even higher (2″ + 1″ = 3″, 2″ + 2″ = 4″, etc.).

Wing will be 1″or 2″ higher than normal when down.  

Pin Wrench recommended – factory used a very strong thread locker!

2″ Wing Extenders™ with Pin Wrench for easy installation – wing is 3.4″ (Coupe) or 4.6″ (Cabrio) above decklid when up / 2″ when down.

For all 997 series cars with Manual Transmission

Automatically blips the throttle when downshifting gears on a manual transmission car. AUTO-BLiP works by monitoring your Turbo’s accelerator pedal position sensor, brake pedal, and clutch pedal, and only blips the throttle when both brake and clutch pedals are pressed simultaneously. AUTO-BLiP reduces mechanical wear on transmissions, improves vehicle stability when downshifting and eliminates the need for heel-and-toe  technique.  Detailed instructions sent with purchase – fairly simple install.

Here is our customer Brian at Leguna Seca – Downshift sounds awesome! “I’m so happy with this product and wish I would have gotten it sooner.
