i currently have my TB and upper plenum of the intake manifold off since i'm in the process of fixing my car. when i took the upper plenum off tho, i realized how dirty and caked up it is inside the plenum.

what can i get from napa or some place like that to clean that out? a friend mentioned something about "sea foam", maybe i misheard him tho cuz i cant find any "sea foam" on jeg's. he also said it would work for injectors too. whats he talking about?

cleaning out the plenums will increase airflow and hp, right?

 

I recently clean some parts of the intake, and I use that handcream that is use for cleaning the oil in your hands after you work with the car.

You just need to apply the product, wait few seconds and remove the dirt with a piece of cloth. In that way you make a nice work without making any mess.
