Description
The 2015+ Subaru WRX Grimmspeed Stealthbox Intake includes everything needed to replace the restrictive stock airbox, And is designed specifically for your vehicle with mass airflow (MAF) sensor adapters sized and positioned perfectly to allow properly metered air to enter your engine without risk of a check engine light. This dyno-proven air intake provides 32 hp/21 tq gains over the OEM intake while maintaining safe air/fuel ratios. Piping is CNC mandrel bent aluminum and comes in wrinkle black or wrinkle red. Also included is a powder coated steel heat shield to keep unwanted heat from the intake.
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.
