I just wondering what the best way is to clean the aluminum on our TPI plenum and runners. Mine is in pretty good shape not dull (never been in snow) but I would like them to look like new. I did a search but couldn't find anything.

 

Look in the tech articles there is an awesome article on polishing and buffing the plenum and runners (and all other aluminum parts as well).

 

Thanks for the referral to the Tech article it was a good article. Unfortunately I am not looking for a polished look but just to make the TPI look as it did new.

 

start with a heavy duty degreaser then clean it with an aluminum specific cleaner and you should have what you want

 

if you don't mind taking all of it off just take it and have it media blasted (glass bead or walnut shells)
