"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!"

"My order needed a slight change and the sales team was quick to make the adjustment. once it shipped the whole order only took about 3 days to deliver 1000mi away. The parts are very good quality "

"Don't have a question. I received my first time order from you and just finished installing new fuel line today. Just wanted to say how impressed I am with your products. You are half the price of the name brand products like Earl's and seem to be of just as high of quality. Thank you."

"Meredith, You're my favorite customer service person of all time, just to let you know how highly I think of you. I tell all my car buddies to ask for you by name."
