Review on 🔧 Dewhel Billet Turbo Resonator Plug Cover Cap - Silver for Chevy 2004.5-2010 Duramax Diesel LBZ LLY LMM: Product Review and Buying Guide by Michael Rosario

Seemed a little wider than it should have been. After lubricating the o-rings, I couldn't get past the first o-ring without trying to bend one of the o-rings. It looks like it hasn't been machined where it should have been and the locating ring groove may have been a bit small. Yes, it must be hard to push in and out, but this is a suction system that doesn't take on excess pressure. It shouldn't be that much pressure.
