"I ordered intake testsers and was able to find the leaks that Ford couldn't. The silicone vacuum hose works great!! Thick walled no collapse, a RARE FIND!!"

"Just got my order, everything looks great! Thanks."

"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!"

"Your products rock! I really enjoy your stuff, it makes building a car so much better. All the angles, bends, sizes, etc-- great stuff. I really like the new intercooler piping that has the heat cores-- too cool. "

"Great blog! I am loving it!! Will come back again. I am taking your feeds also."
