Review on AEM 21 568P Polished Intake System by Greg Simms

WARNING: This product will ONLY fit a 2005 or 2006 Scion tC, contrary to what Revain told me. I have a 2007 tC and ordered it but found the mass air flow sensor to be a bit smaller than the hole in the pipe will allow. So I tried it anyway and the engine starts and stalls after about 2 seconds. I tried finding a rubber o-ring and an o-ring to seal the hole but it just didn't work. The mechanic later told me that these systems have to be very specific, otherwise the sensors will tell the CPU to shut off the engine. Big. Luckily ProParts USA was able to refund my money.
