Review on Mishimoto MMCP 30NPTBL Silicone Coupler Bung by Chris Kirby

Revainrating 5 out of 5

Good product. Easy install

So far this part has worked perfectly for my 04 wrx running speed density. I had to cut off a section but will update as it holds up.

Pros
  • 4 ply silicone and heat resistant built in fiber
Cons
  • Hard to tell
