GrimmSpeed has released their StealthBox Intake System for the 2015+ Subaru WRX. Each intake has been designed out of factory with a CNC bent and laser cut 6061 Aluminum tube for precise measurments and fitment. GrimmSpeed engineers came to the conclusion that an increase in thermal mass of using thicker 1/8" aluminum tubing kept the intake from being vulnerable to rapid temperature change which will result in power loss. Custom MAF flanges are machined from the same 6061 alloy and are placed on the straight nearest the filter, where GrimmSpeed has observed the most consistent cross-sectional flow. Thick 3/16" aluminum plate ounting brackets are laser cut CNC bent for perfect and repeatable fitment. Finally, every little bit of detail is overlooked, even GrimSpeed's included heat shields are laser cut, CNC bent and hand assembled before going to powder coating for a durable wrinkle black finish.

The GrimmSpeed StealthBox Intake System is a stylish upgrade with 14% horespower gains, thats about +30whp! At GrimmSpeed there is so much more than just looks that goes into a product. They wanted an intake that performed right at home in the 2015+ WRX engine bay.
