Great service, awesome prices, incredibly fast shipping. A++ I would absolutely suggest you to my friends and family

quick response and unbelievably CHEAP prices.

Excellent service, quick ship. An easy transaction.

Ordered a set of 5 steel wheels, distributor messed up and only sent me 4. 5th wheel is taking a good couple weeks to arrive due to the distributor messing up the shipment. Autoplicity did make things right and I can honestly say now I would recommend them.

- 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.

Very pleased with Autoplicity's fast and efficient service. The part I ordered fit and looked great. Will definitely consider Autoplicity for future orders. Thanks.
