1992 Q45a

I have been reading about a "Plenum Cleaning." What is that and how will it benefit my car. Also, what could I expect to pay for that type of service? I have just went over 100,000 miles and it is running great. Bye for now.

Best done by hand when the plenum is off for under plenum hose and KS and KS harness replacement. Intake fogging are a mere kiss on the cheek by comparison.

You probably don't want to pay to have the plenum cleaned by someone else, beyond soaking it in a cleaning solution. Even if you have to pay someone to do the rest of the under plenum work, you should do the cleaning of its interior passages by yourself for self-affirmation, if nothing else.
