| AMS Performance AMS 08+ STi/WRX Front Mount Intercooler (FMIC Only) | |
 | The AMS Subaru 08+ STI/WRX Front Mount Intercooler is the best performing direct bolt on you can buy. This durable, race analyzed intercooler core is proven efficient to 800 hp and is 160% larger than its stock counterpart.
The AMS Intercooler features cast aluminum end tanks for added durability with smooth features and geometry. Designed by our engineering team using Solidworks (3D CAD software) these A356 T6 Alloy Aluminum end tanks have improved flow over their sheet metal counterparts. We go beyond our competition to ensure quality. Each AMS Intercooler is hand TIG welded in a jig for a perfect fit and pressure tested to 50 psi to ensure maximum performance.
We tested many intercooler cores to find the best performing core available. The highly efficient 3.5" thick AMS intercooler core is the same as those found on many of our record setting race and street vehicles. Our kit comes complete with intercooling piping, silicone and hose clamps from the throttle body to compressor outlet to ensure a precise fit. The 2.5" 6061 mandrel bent aluminum intercooler piping also comes flanged for a TiAL BOV.
This kit is designed to work with the AMS rotated mount turbo kit, but is also easily adapted to any other rotated kit on the market. As with all front mount intercoolers trimming of the bumper ducting and removal of the factory crash bar is required. An AMS replacement crash bar is optional.

| AMS Performance AMS 08+ Subaru STI/WRX Upgraded Front Mount Intercooler with Blow Through MAF | |
| The AMS Subaru 08+ STI/WRX Front Mount Intercooler with Blow Through MAF is the best performing direct bolt on you can buy. This durable, race analyzed intercooler core is proven efficient to 800 hp and is 160% larger than its stock counterpart. Let the competition know that you means business with a genuine AMS Intercooler but be warned the intimidating AMS logo may scare them off!
A Simple Solution For Big Power On The Stock ECU
In many applications, the standard placement of the MAF sensor on the intake pipe is less than optimal or simply incompatible with the horsepower levels provided by upgraded turbochargers. This is caused by the MAF sensor's calculation of airflow volume as well as intake air temperature.
The blow through positioning of the MAF sensor on the intercooler piping allows the MAF sensor to be properly scaled to a higher horsepower limit than the standard intake provides. You can expect a 90+ wheel horsepower increase in tunable MAF scale over the OEM intake pipe and a 30+ wheel horsepower increase over an aftermarket 3" intake with MAF.
Another benefit of a blow through system is the ability to use a 4" intake pipe over the conventional 3" piping. This equates to more flow and ultimately more horsepower. In addition, the AMS blow through intercooler piping allows for an atmospheric blow off valve to be used without any negative side effects. Due to the blow off valve's placement before the MAF sensor, no metered air is lost and therefore no over fueling is present in this system.
Engineered Quality For Superior Performance & Durability
The AMS Intercooler features cast aluminum end tanks for added durability with smooth features and geometry. Designed by our engineering team using Solidworks (3D CAD software) these A356 T6 Alloy Aluminum end tanks have improved flow over their sheet metal counterparts. We go beyond our competition to ensure quality. Each AMS Intercooler is hand TIG welded in a jig for a perfect fit and pressure tested to 50 psi to ensure maximum performance.
Ultimate Efficiency And Superior Quality
We tested many intercooler cores to find the best performing core available. The highly efficient 3.5" thick AMS intercooler core is the same as those found on many of our record setting race and street vehicles. Our kit comes complete with intercooling piping, silicone and hose clamps from the throttle body to compressor outlet to ensure a precise fit. The 6061 mandrel bent aluminum intercooler piping is 2.5" for the "hot pipe" (turbo to intercooler) while the "cold pipe" (intercooler to throttle body) is enlarged to 3" to support a Blow Through MAF flange and also comes flanged for a TiAL BOV. The 3" cold pipe also allows for a larger volume of air to be transported to your engine, creating more horsepower than a standard 2.5" pipe.
This kit is designed to work with the AMS rotated mount turbo kit, but is also easily adapted to any other rotated kit on the market. As with all front mount intercoolers trimming of the bumper ducting and removal of the factory crash bar is required. An AMS replacement crash bar is optional.

| Turbosmart SUBARU STI DUAL PORT | |
 | WHEN TO CHOOSE A MODEL-SPECIFIC BOV?
If your vehicle is running higher than the standard boost level, you should upgrade the factory BOV, as it is designed to leak boost!
The Model-Specific BOV range has been designed to cater for cars with engine bays with space or design constraints that make fitting a Universal BOV difficult or even impossible.
WHY BUY A TURBOSMART MODEL-SPECIFIC BOV?
Ideal upgrade from a factory valve, Turbosmart Model-Specific BOVs provide protection for the turbocharger by reducing turbo cavitation on throttle back-off and gearchanges while also reducing turbo lag between gears for even greater performance.
All Turbosmart Model-Specific BOVs feature a simple tool free
adjustable cap used to tune the operation to personal preferences.
Quick and simple "bolt-on" installation with no need for any vehicle modification. All parts supplied in the box.
Four BOVs in one. The Dual Port can be configured as a Supersonic, Megasonic, Plumb Back or Dual Port! Features sequential ports for quiet operation on mild boost and full performance at full boost.
