"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!!"

"I finally got to test my new silicone intake and it worked perfectly fine. There are no issues with the hoses colapsing like my friends suggested might be a problem. Thank you! Thanks to Holly, Sean and Jon for quick feedback about fitment!"

"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!"

"Thanks for resolving this issue so quickly. This is truly exceptional customer service. You count on me for another purchase should the need arise."

"Thank for quick and easy solutions to our silicone needs. Your website is so well designed and everything is easy to find it only took us 3 minutes to find everything! Keep up the good work guys!"
