Get a polished plenum or buy the Crawford cast plenum and strut bar.

(the ceramic looking piece on top of the engine behind the plastic) looks kinda rusted i guess? I dont think its rusted its more of a discolored look. Check it out and give me ideas of what you think it could be please..

This thread is a little old, but just wanted to know if you figured out what the problem was. I live in Miami too, I have 40k miles, and my plentum looks nothing like that.

my intake on my truck did the same thing after a while. scrub it with fine steel wool, like 00 or 000 grade. i coated mine with clear POR-15, still looks as good as new 2 years later.

it is aluminum oxide. The equivilent to rust on aluminum. Most of it will wipe off with a coarse rag. steel wool will take the rest off and if you want to be really pretty you can buff it out to look like it's been chromed.
Everyone thinks Cali cars don't have this happen. They do if not garaged properly or if you live by the ocean.
