Well, I was bored today....and also broke. as I was looking around in my garage. I noticed that I had a1/3 sheet of aluminum left over from my previous DIY for my turbo 240sx. So I was thinking to self. " Self! what can I do with this??" it says...ur Evo open airfilter can use a heat shield!!. so i went to work, and the result???
it was very simple to make. only a few hand tools are needed. ie: sheet metal of some sort ( aluminum is prefered), sheet metal cutter, flat head screwdriver., and card board for template.
and u should have it done in under a hour.
* before u do most of anywork under the hood please disconect the ground wire, u don't want to accidentally pop the air bags.
** do it at your own risk, as I'm not responsible for any damage/s caused to u or ur vehecle.
ok here is how.
1. remove the airfilter from the adapter using the flat head screwdriver.
2. start with the card board and make a template.
3. trace the template on to the sheetmetal.
4. cut it away ( please wear heavy duty glove to protect ur fingers from getting cut from the rough edges of the sheet meatal).
5. prefit and trim until it fits perfectly.
I did not feel any gain in hp, but the air filter used to get hot after a drive, and after I install the heat shield, the filter temp is almost the same as the room temp.
So that have to be good.
I'm making another one soon ( either another heat shield or an entire box) and will do a detail procedure with pics, SOON. C
