| Aeromotive 340 Stealth Fuel Pump | |
 | The Aeromotive 340 Stealth Fuel Pump is a high-output, in-tank, electric fuel pump that fits most popular EFI applications. The Aeromotive 340 is a compact, lightweight pump that bolts into many existing hanger assemblies.

Over 30 percent more flow. This pump is ideal for applications requiring more flow while retaining the factory lines and mounting provisions available in the Original Equipment (O.E.) configuration. The 340 is also perfect for use as a universal replacement for applications that require more flow to support forced air power adders such as turbo and supercharged applications. | GSP Price:

| APS Cold Air Intake System - 65mm | |
 | The APS smooth bore cast aluminum cold air intake system and air filter deliver a huge volume of cold air to the turbo charger for maximum engine performance.
This APS cold air intake system is certainly the most cost effective way to achieve greater air flow, great looks and fantastic sound for your sedan or wagon.
Unlike ram pods which source hot air from under the bonnet, the APS system breathes cool air from the inner guard for the optimum engine performance and durability. More importantly the air through the APS high flow air intake system is consistent in temperature. This means that the engine management unit's temperature compensation system operates correctly - unlike devices that source air from the highly turbulent areas under bonnet.
And, it's easy to install with no cutting or drilling required.

| 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.
