"cold air intake for my civic at 1/4 the price, and 10X the looks"

"Ive bought a bunch from you guys great price and quality I recommend you guys to many of my customers"

"Just wanted to let you guys know that your site is great and I linked it on one of my local automotive forums. After i get the products in and install I'll more than likely be posting it up on some national/global mustang boards if all goes well..."

"Thanks for the response. We have an inside joke that you guys only hire ninjas with how fast your service is. SIS is definitely the first place I check for parts. You guys have a great thing going on there. Thanks!"

"...the liquid to air system I purchased from you works awesome. I have a 5 gallon fuel cell for a water tank. I fill the cell with 22#s of ice, plus water, and after a turbo run there is no ice remaining in the cell!"
