Great price! Quick shipping. The intake I ordered was $20.00 cheaper than anywhere else I looked. Item was instock and shipped quick. Will order from Autoplicity again!

Couldnt order without logging into amazon

Of 6 other vendors I'd found, every one listed the exact same price for the product. Autoplicity was well over 10% less. Although it's like an instinct for me to shop around & compare prices, I would expect that Autoplicity will be the hands down winner on any & all future purchases. I don't know how they do it...but who am I to question them saving me lots of money!!

Fast and easy, best price on the web for what I ordered.
