- Good Purchase
- Overall it was worth it! The price is a bit steep but you are getting a CARB legal intake which make this legit. I do appreciate the small performance gain and how it nicely fits the engine bay. The main reason why I bought this was for the sound and its sounds great! It would be nice if AFE made more products for my car.
