Great price fast delivery

Quick and easy! Love the discounted shipping as well.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Oh my god, my car rips now. Scary improvement. Will buy again, and aeromotive will have my lifetime support. Much love!!!

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.
