| Mentions "plenum mass" and references removing material when polishing. Are you speculating about the top of the plenum or do you know for a fact that its just a byproduct of the casting process and nothing more? Don't want this to be like the rockguard where someone local said it was Nissan being lazy about wetsanding. Some facts: Plenum is hot as shit. Even after mani ceramic coating, want to do as much as possible to replicate my NAs plenum temp. You're gay.
