Not too bad for the price. Don't rely solely on the pictures in the instructions, as they showed the MAF sensor installed backwards. Fit was not perfect, I had to trim some of the metal housing in order to install it. I had to force things a little as things did not align perfect. I didn't notice a difference in MPG. Seems to be a slight increase in throttle response & maybe less turbo lag. I do enjoy the sound increase, much deeper growl, it sounds great with the windows down. No regrets.

Easy to install (about an hour), looks good, fits good. Performance improvement slight - I got this because I have an upgraded intercooler, high flow cat and exhaust. Besure to put silicon sealant on air box screws otherwise air will get into your engine without going thru the filter.
