Vehicle Fitment:
2001-2006 Evolution 7/8/9

Intake Manifold Fitment:
This kit is designed to work with any intake manifold that utilizes the factory throttle body location, including OEM, Skunk2, JMF Sheetmetal, Driven Innovations, AMS F1 and so on. This will not fit with the JMF Billet manifold.

Throttle Body Fitment:
Select the proper coupler size to match your throttle body in the purchase menu. We offer a 2.5-2.75″ to match the stock TB or a 2.5-3″ which fits with the S90 70/74 and the Full Blown. Please double check your TB size if you have another style.

Battery Fitment:
These pipes will not clear a factory-sized battery. The STM Evo 7/8/9 Small Battery Kit is recommended for install.

Intercooler Fitment:
These pipes have been test-fitted and are compatible with the STM, OEM and Buschur intercoolers, and they will also work with any aftermarket intercooler utilizing the stock-placement of piping such as ETS. The included 2.5″ coupler will fit a 2.5″ intercooler outlet (which is standard on most intercoolers.)

Blow Off Valve Fitment:
We offer the aluminum pipes with a flange for a TiAL, HKS, Greddy or stock blow off valve. The stock valve will require a custom hose for recirculation.

AIT Bung & Plug:
All STM UICP kits will include an AIT bung welded onto the bottom pipe that connects to the intercooler. If you do not need to run an AIT sensor, we also include a black plug to seal it off.
