About This Item

The intake for the 15+ STI can be compared to a cross between the Stealthbox heat shield in the 2015+ WRX intake and the tube and filter utilized in the intake for the 08-14 WRX. Small design modifications were made, but overall fit and performance remained fairly consistent. Of course, just like with other GrimmSpeed goods, we offer you a customer experience that will encourage you to stand behind these kits as well.

Why Choose GrimmSpeed Stealthbox Air Intake

This explanation can be complicated and drawn out at times, especially when performance is involved. It's easy this time. The engineering and production teams at GrimmSpeed are renowned for creating goods that are made of premium materials, have an excellent fitting, are expertly crafted, and are long-lasting. These intakes are no different, offering the tested performance of the 08-14 WRX EJ motor intake with a look and feel that set it apart from the competition (third-party results coming soon). You no longer have to appear as though your factory airbox has been replaced by a shoe box thanks to the Stealthbox intake heat shield.

NOTE

  • Take care to install the air filter onto the intake tube properly. Push the filter onto the tube no more than 1" before tightening the clamp. This will ensure that the velocity stack within the filter is allowed to function properly!
