Does anyone know of a product that will clean thing up under the hood ? Aluminum intake (big one for me) and aluminum parts, crab, nasty grease build up (something to soften it up in order to scrap it off) and other tips, tricks that people may have

well that is you problem, you have crabs under your hood. dirty little things they are.
maybe you can chase them out and put a carb there?
do a search on cleaning up alunimum and you will find hundreds if not thousands of suggestions. one member actually went from a rough sand to ultra fine steel wool and made the alunimum look like chrome.
and i have the same problem - my computer just cant spell wither. lol
use search - play with it - one search every 60 seconds or so.

Thanks for the info crabby

One suggestion for cleaning really greasy grimey goo is brake cleaner. It's not cheap when doing large areas, but it cuts through just about any grime, and it totally evaporates, leaving no residue what-so-ever. I always use brake cleaner when cleaning mating surfaces to make sure new gasket sealer sticks.
