Please, for the love of god use proper grammar, that hurt my head to read.
On topic, I have one and the quality obviously isn't AEM quality, but $50 compared to $250, I don't think you'd notice a difference to merit the added price. As PumkinSVT said, swap a decent filter on and go for it.
thanks 4 the advise where in the rpm range do u notice a gain, b4 i blow my motor i was using a pos pep boys short ram and i had my friend cut it short and so times it came off and put it on in the middle of the road
I have one on mine, about two years now no problem. I switched it with a Injen filter and a outter wear prefilter. Like said above just switch the filter out, but once you see the ebay filter you will be like WTF is this.
