The most complete cold air intake kit for the Porsche 997 Turbo & GT2. Gain horsepower, improve throttle response, reduce turbo lag, gives your engine a more aggressive sound.

Cone air filters provide plenty of flow for the turbos while the aluminum intake pipes keep the air flow smooth & laminar for proper MAF functioning. The final touch is the carbon fiber cover which securely connects to the aluminum shield

As you step up the power level on your Turbo, having proper cooling efficiency is mandatory to maximize your turbo performance. heavily benefit from the use of upgraded intercoolers. Developed these complete intercooler replacements, however some Modification to the plastic housing is required to fit these intercoolers.

The intercoolers fit all Porsche 997 TT and GT2 Models Dimensions: Thickness: 80mm, Volume over standard intercooler: +40% Efficiency: +85%, Flow rate: 620 CFM ,Pressure Drop: less than 1% Use Up To 750+HP

Larger GT2 throttle body & plenum kit for the Porsche 997 Turbo to gain added performance. The point of a larger throttle body is to get in more air. The more air, the more power you make. The plenum kit includes Larger throttle body, (Standard is 75mm). Since most 997 Turbo users drive their car on the street and track, we developed this product to substantially increase throttle response and improve "usable" power. The T plenum features the stanard fittings for vacuum hoses & breather lines & includes a 1 way check valve needed. The installation requires removal of the factory airbox & Y pipe for access & takes approximately 2 hours. DOES NOT require the ECU to be remapped . The factory ECU will adjust accordingly to the change in throttle body diameter. However, corresponding mods including an ECU remapp will bring out additional power. As it stands alone, the plenum kit will add a bolt on 20 wheel horsepower to your Porsche 997 Turbo.

These OEM Boost Recirculation Valves (BRVs) for the Porsche 997 Turbo VTG turbochargers. Like on the older 996TT, the stock valves use a rubber diaphram which will leak boost on the higher RPM. This part also deteriorates over time leading to boost failure. Agency Power BRV uses a piston & spring design. This design holds boost pressure all the way to redline & with the VTG design, helps boost come in stronger.CNC machined, the base of the valve was precision engineered down to the ten-thousandth to fit into the stock VTG turbocharger. Inside the base is an aluminum piston that has been 3D machined. This piston is hard anodized & with the provided grease & o-rings, provides an air tight seal as the piston moves up & down. Agency Power spring rate will handle stock boost or high horsepower cars.

Based on the factory P9511 tool, STOMSKI RACING's version of this tool incorporates a brass cap and a double-ended stainless steel sleeve to install the O-rings on the crankcase through-bolts. By using it, the brass cap to protects the delicate O-ring from getting cut on the threads of the bolt, you can then use the "thin" end of the sleeve to slide the O-ring over the brass cap onto the shank of the through-bolt. Once the o-ring is clear of the threads, remove the SR024 brass cap and flip the SR024 stainless steel sleeve over and use the blunt end to securely and gently seat the O-ring in the recess on the crank case.

Simple Allen Key Lock Single Action.

By using computer engineering and digital design STOMSKI RACING has developed the FIRST truly symmetrical 911 Semi-Solid Engine/Transmission Mount, thus allowing you to run stiffer mounts without sacrificing comfort or ride quality.  Our symmetrical design allows you to custom tune your ride- determining feel, function, and fun.  Because our SS mounts are SYMMETRICAL, you can now properly use them either as an engine mount OR inverted as a transmission mount on Boxster & Cayman models. Unlike other non-symmetrical SS mounts, there is no compromise when using SR135 inverted as a transmission mount because SR135 is symmetrical and thus FULLY supports and FULLY absorbs in BOTH positions/directions. Road tested and track proven, STOMSKI RACING's SR135 provides better shifting, better weight transfer, better handling, crisper throttle response, better acceleration, and of course GREAT looks, without any loss of comfort.  Mounting  comes complete with an  aluminium housing, stainless steel sleeve and disks spacers & a M12 Schnorr washer.
