Grimmspeed Stealthbox Cold Air Intake for the Subaru WRX STI Red Piping

Subaru WRX STI Stealthbox Cold Air Intake made by Grimmspeed
Grimmspeed has created and developed a Stealthbox Intake for the Subaru WRX STI platform! Available in either red or black piping, featuring an air straightener that dimensionally mimics the factory configuration for accurate MAF sensor readings. Included in the kit is a custom reusable high flow air filter that has an integrated velocity stack entrance that smooths incoming air. Increasing overall performance while also adding a little bit of a deeper intake noise. Proudly made in Minnesota U.S.A!
