All i can say is wow, i was under the impression that this stuff was just a fluke they promise 4-10 whp. So i think yeah right, but for $6 why not try it, it took five minutes and what a differance, more response, faster rev and a real nice tone. In cunclusion the CRC MAF cleaner is well worth the $ espesially if you run a K&N mine was filthy and now the car feels brand new.
