If this is the wrong area to post this, please correct me. I'm usually not one to post on the forums but this is an issue. I have been seeing a few horror stories of MMP products basically blowing up motors and the guys there are blaming it on other things with no fault of their own. I bought an mmp charge pipe/ bov prior to seeing this stuff because the price point was good. I had already purchased a tial for my 535 and didn't wanna buy another. The car ran great, until a couple of weeks ago. The car was running sluggish. it didn't sound right. I started to notice the blowoff valve not opening as quickly as it did, then the blowoff valve got to where it would not open at all. I decided to take it off and do some maintenance thinking it was just sticky etc. Well, upon removing it, I realized there were pieces missing from the bottom of the BOV. I immediately pulled the intake manifold. I didn't know what I was looking for, but I knew something came loose and I thought it was in my motor. I checked the first 5 ports and nothing, but port 6 held a surprise! the magical piece that came off the bov. I got really lucky. the piece was too big to get down into my valves/motor but it could have been horrible. I will never buy anything from them again. their laziness and cheap Chinese parts could have blown my motor. I know parts of theirs have led to the demise of other peoples N54s.
