xxxxxxx

Shipping charge is way out of line

So far so easy . . .

So far so good, Autoplicity had what I wanted at a reasonable price, in stock and shipped within a day or so of order placement. I would ordere again, if I needed to do so.

Fast, easy...good experience.

Fiest time here if it works I ll be back often

Great customer service. My product came quickly and just as described. Can't beat the prices anywhere on the internet, I looked for 2 months before buying. Thanks!

I felt I had to double check with Centric site as your brake shoe compatiblity chart didn't seem to go past 1956.

This is the best price that I found on the AEM methanol injection kit! I and searched all over! Fast shipping and processing! I would buy from again!!
