Mui bien

Excellent place to deal with. I am a returning customer and love the fast shipping!!

First time buyer. Ordered Sunday. Shipped out Monday. Fast Shipping. Good prices.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

- Updated review -<br>Autoplicity.com contacted me after my original review and admitted to making a mistake with my order. They have refunded my shipping and I am happy now.<br><br>- Original review -<br>After 18 days the part finally arrived. The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.

The correct product that I ordered, and easy to find through there web site.thanks

Best price online for an Injen intake. Arrived in a week. Appreciated the "Item shipped" email with tracking number!
