Has anyone had any success cleaning the TPI intake plenum and runners? If so what did you use, what was your process?

 

Inside or outside?? I used the search feature. Lots of good solutions in there. Google works awesome too. You can even throw my username in there...

type this search string into Google and read the first few links.

Thanks Drew. I'll do some research. I'm really interested in what I can use to clean the outside to bring them back to factory fresh.
