"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!"

"Your website is a life saver, i would have spent double this at my local performance shop. "
