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.

Overall a good bang for the buck

Reviewed By Carl R (WINCHESTER, VA) Reviewed for a 2014 Audi S4 —6/30/2016 5:40 AM

considering the cost/performance and lack of availability of other options I decided to go with the Injen Intake. Price is very good through AA and I'm thus far pleased with my decision. My car is Stage II so I can't say I notice any real difference in performance but I do like hearing the supercharger sing.
