I got and installed my ram air intake and cleaned my MAF sensor. got the intake for $65 off ebay. It's a no name but I believe its identical to the HPS intake sold by the same seller. The hps comes painted and with a K&N Filter, bit the pipe is the same. For instructions they sent me Instructions for the K&N Typhoon intake. This leads me to believe i got a $65 version of a $150 intake thats a ripoff of a $25o intake. So i'm pretty happy with it. It sounds great aswell. My Mileage has also seen an improvement.
