    Liquid paint won't last on aluminium no matter what you do. Only powder coating but i think that would affect the heat transfer. I would just remove it and clean it well if i were you, or polish it :D

    As above, unless it's done properly you will affect the way it works. Remove it and get it shot blasted?

    oh right so adding a coat of paint or even powder coating will effect the cooling of the car ? thats a bit of a bummer as i dont want to fit an s3 aluminium intercooler heard its a lot of work and obviously the price tag and the question of not needing it as my car isnt running high enough boost/power

    looks like ill be leaving that exactly how it is then
    thanks for the quick responses

    I went the other way on my MX5, painted the IC black so it wasn't so obvious

    [​IMG]

    10 years on with daily use and a pretty regular track thrashing and the paint hasn't pealed or come off.
    Did some temp readings before and after and it made absolutely no difference to intake temps.

    Should point out that i am in Greece so that's 10 summer of mid 40c's ambient temps.

    You can paint aluminium, you just need to get the right paint and primer.
    I used high temp paint the same as i used on my cam cover and supercharger, again no problems on either with peeling or paint coming off.

    I painted the valve cover and intake manifold on my 1.8T and the 16v i had in the past, always high temp paint, with and without primer, failed in every way, i can scratch the paint with my nail. Next time i'll go for powder coating for aluminium.

    Aluminium is no different to steel, many cars my MX5 included use aluminium panels again with absolutely no problems.

    The key is to make sure the surface is absolutely spotlessly clean, for cam covers you also need to go over and give it an extremely thorough degreasing, then go over with a scouring pad to give the paint a good key.

    Etching primer is also a good idea if you've had problems before.


    I can say that my aluminium IC that has been painted for 10 years cleans up as good as new, as does my cam cover and supercharger.
    Worth pointing out that my supercharger regularly hits 200c after hard use, again absolutely no problems.


    It's all in the preparation :thumbsup:
