Injen SP Series Cold Air Intake Reviews


Great product

Reviewed By Jacques V (HOUSTON, TX) Reviewed for a 2014 Audi S4 —9/6/2016 10:42 PM

Solid product, delivered on time, with easy to install directions. The supercharger has a nice subdued whine and really wakes up the throttle response. An easy upgrade that makes the car sound great.
