everything was easy and fast

Very detailed list of part fitment. Radiator fits and functions very well. BUT, and this may be no fault of Autoplicity, I received the radiator w/holes punched in the box and some of the cooling fins bent. It wasn't bad enough to warrant a return, thoug

Thank you!

Quick and easy.great price

Easy and fast

Autoplicity had the best pricing I could find. I ordered my items on Saturday and am having them delivered today (Tuesday). <br><br>Thanks again I will for sure do business here again.

Easy, comfortable, smooth.

Great service, awesome prices, incredibly fast shipping. A++ I would absolutely suggest you to my friends and family

very fast shipping and very cheap prices

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

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.
