Good fast shipping. Easy ordering.

I recently ordered 2 Borla Dual Round Intercooled Tips from Autoplicity.com for one reason and reason only...their prices can not be beat! No where else online can anyone match them! <br>

easy

I am glad I found Autoplicity! Great prices, fast shipping, and excellent customer service. Already looking at other items to purchase from them. I highly recommend using Autoplicity!

I have to say I was skeptical at first because autoplicity's price beat everyone by so much! Then I estimated my shipping charges with their system and that too was real cheap for this heavy item I ordered! I ordered it on Sunday and it showed up on Tuesday afternoon! So exceptional pricing meets exceptional shipping and my item is the real thing for a lot less leaves me completely satisfied with this company! I will be recommending them to my friends and family, thanks!

Quick &amp; fast services!

Very satisfied. Good price and quick delivery.

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.
