Good

Easy process,, reasonable shipping.

Extremely easy and the best price by far.

Best Price and fast shipping, not bad price for the shipping cost

Found the K&N filter for my 2012 Acura TL at Autoplicity for the best price and delivery took about 2 business days. Can't ask for more.

Awesome prices and fast quality shipping. Order Number: 6095<br>

Quick and easy

Quick and easy ordering. Thanks.

It is awesome that you guys can get this part! Half the cost of competitor. As long as shipping goes well, I will definately be shopping here more often!!!

I'd like to make sure if they are all original Bosch and

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34
