"WONDERFUL! Shipping is blinding fast! The site is great because there is an automatic inventory counter to tell you what is in or out of stock. Great site! Ordered from them several times without a hitch at all. And not to mention that their prices are CHEAP! "

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

"If you guys have any siliconeintakes.com stickers, that would be great if you threw a couple in with the "cat", I love your website and would love to promote it. You guys have the best prices by far!"

"Your customer service is absolutely top notch!! I will definitely continue to do business with you guys in the future and try to send as many people your way as I can. Thank you again!! Brandon "

"Thank you for having the best prices that I can find. I have looked for hours on line and spent hours going from auto parts house to parts house and you have the best prices around."
