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.

Manual Boost Controller for your turbocharged vehicle. Designed with performance, fitment, & style in mind, the AP MBC Gives turbo vehicles much need horsepower with a couple of easy twists of the unique adjustment knob not seen on any other manual boost controller. How does it? Simple! A bleed valve design, which has you connecting the hoses on either side to the compressor & the wastegate of the turbo. The MBC controls the airflow through the valve by the adjusting knob. Loosen the knob & more air moves for higher boost pressure. Tighten the knob down & restrict the flow for less boost pressure. The AP MBC includes 2 feet of 5/32 vacuum tubing, a flexible aluminum bracket that bolts to the MBC & has predrilled holes for universal fitment. For 996 & 997 Turbo Models.

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.

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. Sold as 1 Pair (2x Mountings)
