Review on Boost Monkey® Ultimate Hardware Install Gaskets by Bobby Aghetoni

Used them to replace fried OEM downpipe/interleaver gaskets on an N54 BMW. Landing is fine, no leaks. I see no reason to pay OEM prices when these pads work just as well and cost many times less. It will be interesting to see how well they hold up over time, but for now I wouldn't hesitate to buy them again. Updated 10/2019 - I had to replace the center pipe which used these gaskets to seal big surprise that the gaskets stayed intact. I wasn't expecting this as the standard BMW seals (which are 3x more expensive) would have completely collapsed by this point.
