So as some o you know I wrecked my head gasket ad my MAF sensor, I'm doing the head gasket now but am just wondering if anyone has tried te bosch mafs from eBay? I'm assuming they are the same as the ones from the stealers but just wondering if anyone has tried it? I'm going to buy a new MAF from TPS, £95 after taking my old one back in, but eBay is about £20 cheaper, anyone tried these?
