Universal SD Intake Pipe Kit by STM

The STM 4" Universal SD Intake Pipe Kit is for use on cars with no MAF and a 4" turbo inlet. This kit is designed to be modified to fit your specific set up. The aluminum pipe can be cut to size and the giant, 4" silicone coupler is more than enough to accomodate any custom set up. We also offer an optional K&N Breather Filter to vent your crankcase if needed. This is a perfect solution for the DSM and Evo 8/9 applications.
