has anyone tryed polishing there plenum while still on the car was thinking of trying it

 

sure, you could make it look better, but these things are so easy to remove, why bother?

 

Do your back a favor- pull it off and polish it. It took me forever to do it right- I can't imagine doing it while bent over the engine bay!

 

I did. About 15-20 hours later it looks exacly how I wanted. I polished my AC bits installed as well. As micktroup2 said, I felt it a little over the few days I did it in. Not my back tho. Just my legs and hands (hand sanding will do that) but I'm reletively young.

58mark, my reason was because I just didn't feel like removing it or buying new gaskets.

 

I have reused the gaskets several times (I always snag a couple of extras of various gaskets when I am at the the junk yard though, just as backups) but this last time I bought some gasket material from Pepboys for about $7 and cut my own. Makes it a lot easier and a hell of a lot cheaper than the dealer, given that I can make just the gaskets for the top plenum, instead of having to buy the entire kit...
