so far so good
So far this aftermarket intake assembly is performing as advertised. Codes cleared and staying off for now, although it's only been on one day. After reading bad reviews on the same part badged differently from a different seller, I was hesitant to buy this from an unknown seller. One guy said the part failed and damaged his turbo (Mohammed something with a Z. all I can recall ATM). sumyola advertises a 1 year warranty on their intakes, so if it fails within that timeframe i will update this review to reflect that.
