Intake Polishing Question

[DSMpwr25]

Any body polished the stock 1G Intake Manifold. I got one and i cleaned it all up and just want to polish it. thats the look i am going for under the hood. What kinda tools did you use? how did it turn out? thanks

i'm trying to do the same thing...honestly the only way i'd think you'd get it really clean is to sandblast it or beadblast it...the before and after results are nuts with those things

sandblasting the manifold would be a good start, get it very clean

Polishing one of these intake manifolds is a giant pain, you'll need to start with probably 200grit sand paper, and work your way down in steps to 1500 or 2000 grit, the finer the grit you sand down to the better the results, you'll need some white and red rouge, starting with the coarser of the two, use some type of high speed rotary tool w/polishing wheels to start working the shine out of the metal..

I can go into detail, but its honestly too much work for a stock manifold

200
When I did my throttle body elbow I started out with 40 or 80 to take out the big casting flaws. 80 then 180 - 320 - 600 wet 1000 wet that's where I stopped but it might not be a bad idea to go to at least 1500. I used mcguires super coarse bufing compound then medium. I haven't used the rouge but I am sure they work better on aluminum. I also don't think I would touch this project without power tools I would at least suggest a DA or random orbital sander, die grinder or drill with barrel sanders as big as possible but small enough to fit in most areas, and as many accessories as you can afford. Otherwise it will take you months with bleeding fingers.

true, if you are a perfectionist, start with a lower grit, I've found 200 grit usually works good enough for me, but then again, I dont polish things that are as rough as the stock intake manifolds

Use a mouse sander or simiar to start with.
