  • Compatible with engines without VVT or AFM systems
  • Optimized lobe profiles for improved throttle response and power delivery

Features & Benefits:

Great customer service. Fast order processing. Hassle free transaction.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

I like the site The only thing I didn't like Was they gave me a bad tracking number

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!
