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 cast end tanks are aluminum & then precision welded to the thick racing upgraded cores. The ends of the intercoolers are designed to work with factory boost hose fittings or AP silicone boost hose kit. The intercoolers retain the factory mounting positions and come in a polished finished. The intercoolers fit all Porsche 996 TT and GT2 vehicles Dimensions: Thickness: 80mm, Volume over standard intercooler: +40% Efficiency: +85%, Flow rate: 620 CFM ,Pressure Drop: less than 1% Use Up To 750+HP

Important upgrade for the 996 Turbo to replace the factory Bosch diverter valves. These valves are prone to leaking pressure & will taper boost off with the diaphragm design even at stock boost levels. To help keep the boost pressure constant all the way to redline, upgrading the stock diverter valves to the Agency Power Racing Diverter Valve Kit will improve your cars overall performance.

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.

Gives Porsche 996 Turbo owners another 20 hp with this new BIG MOUTH plenum & throttle body kit. Agency Power set out to engineer a plenum that was functional, did not require additional tuning, & simply... made power! Retains the same shape as the factory T Pipe with reduced restriction, the throttle body. The factory throttle body is 75mm ID and increases to 82mm ID Throttle & plenum. This kit uses a 82mm Factory Turbo throttle body and has all the necessary vacuum & breather hose ports as stock for a true bolt on application. Tested on a 2001 Porsche 996 Turbo, achieved a gain throughout the entire power band with a peak gain of 20hp & 20ft/lbs of torque. Includes both the plenum & throttle body for all Porsche 996 Turbo, X50, and GT2 from 2000-2005.

These EuroCupGT Diverter Valves replace the factory valves to provide faster response & reduce lag plus sharpens throttle-response - meaning faster acceleration & improved driveability. Throttle is smoother & feels more accurate. reliable time & time again. Inadequate/defective standard valves are noisy, create extended lag, loss of boost, sluggish throttle response. Straight forward fitting. The factory plastic valves really limit how power is delivered to your Turbo & will limit performance like a restricter. Without uprated valves the ECU tuned car will just hit the boost limiter sooner & thus no real power gain will be made! Running more boost will allow you to maximise your power map & any subsequent mods you may choose to make to your car. The EuroCupGT Billet Alloy valves are sold as a pair (2). Fits all Porsche 996 Turbo / X50 & GT2 models 2001 to 2005. and Cayenne Turbo / Turbo S

Porsche intake system is restrictive, dyno tests have shown this adds upto 23 hp. The intake tube provides a direct, unrestricted path to your engine for maximum airflow.

Gain of nearly 25 hp K&N tested on a 2007 Porsche 911 GT3 RS 3.6L on our in-house dynamometer. An increase of 24.65 hp @ 6726 RPM. Dramatically reduces intake restriction & smooths & straightens airflow. So the engine uses a larger volume of air than the OEM assembly. More air means more power & torque. System uses a conical shaped, carbon fiber top, high-flow air filter & powder coated two-piece aluminum heat shield. For All 996 GT3 Models.

The compact, efficient design of the M96/M97 oil-to-coolant heat exchangers has proven itself useful for other than engine cooling. By remotely mounting M96/M97 exchangers, gear box and/or steering rack temperatures can be reduced and the life of those components significantly extended. STOMSKI RACING's M96 Heat Exchanger Adapter allows for convenient remote mounting and includes your choice of -6 or -8 AN fittings. This high-quality adapter plate is CNC machined from 6061 aluminum, anodized for years of service and includes seals and hardware.

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)
