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.
Super easy + best price on the web. Very pleased am I.
Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
