Need a replacement oiled filter for your GrimmSpeed Intake? GrimmSpeed has your back! This intake filter is dimensionally identical to our air filters that are included with the GrimmSpeed WRX/STI/BRZ/FRS/LGT intakes. This filter uses a high-flowing oiled element.
Made in USA
Integrated Velocity Stack
Oiled Element Filter
** INSTALLATION 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! **
