Great purchase .
Pretty happy with the product... it comes complete with everything you need , fairly easy to install. As for performance side it gives a little boost and faster throttle response, don't expect night and day difference and also makes it better with higher grade and better quality gas . Shipping was fast , it helped probably cause it came from California and so was the rebate check. All and all , for the money, I'm really happy with it and love the sound as well.

I should of just brought the filter (Volant 5113) Air Duct was not any larger than stock, but does have a smoother inner liner for better air flow. Air box/Filter cover needed extensive trimming and does not fit that well. I also had to add a bracket to keep the air filter from rattling inside the air box between cover and washer fluid reservoir (even with 7.5" weatherstrip trim installed) Has slightly better pick up with slightly more intake growl.
