Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

After a almost 2 month backorder through Summit... y'all had what I needed in stock and shipped same day! Which was delivered in 3 days! Awesome!

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
