Great price and good company to buy from!

Good price and sound nice on my buddy's truck

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
