Really hard to find plugs - autoplicity had over 100 "in-stock" - great price also.

super easy! thanks!

Amazing shipping speed!!!!! Best price on internet! Item arrived as described. Will do business again!

Was quick and easy

Good so far.

thanks

Great price and fast shipping!!!!

Autoplicity has some of best prices around and also ships extremely. Their customer service staff, either online or on the phone is also easily reachable and helpful!

Very easy site to navigate and order from.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.

Good so far. Will see on shipping and part. Thanks
