I've done the follwing free mods:

FRA(Free Ram Air)

Ported and Descreened the MAF(Have followed up this mod with computer tuning, since it makes the car run a bit lean)


The two following links will give you a good writeup on the free mods.

Enjoy

The only two free mods I can remember are the FRA (free ram air mod) and throttle body bypass. I don't recomend the FRA. I did it on my V6 camaro and it got the air filter dirty real fast and has arguable gains if any.

You should do the throttle body by pass if you don't leave in area that gets very cold. It's pretty simple to do. Technically it costs money but it's so cheap it's usually called a free mod. I just bought one of the kits off of ebay for $10 instead of running around trying to find the parts.

The TB bypass kit can be bought for around $13 shipped

I believe the best free mod is weight reduction.

Remove the windshield washer reservoir if you don't use it, that t hing is pretty heavy.


The FRA will give you gains from a roll, from a stop it doesn't do smack. And expect to change your air filter at 2000-10000 miles depending on where you live.

How do you do the FRA ?

Don't do it, don't do it, awww cr@p... I warned you.


Since your going to go ahead and do it: I don't think it's in the directions but when doing ram air your supposed to block off the stock opening or else the pressurized air just goes out through the stock opening. The ram air kits you buy come with a piece to block off the stock opening, I used caulking.

Most places offer a deal on buying a whisper lid and k&n which is cheaper then buy them seperately.

if you bought an ARA (old SSRA) kit and installed it you think it'd would be ok with the FRA done? the metal sleeve attaches right under where the peice is cut off for the FRA mod (i think?) so it would prolly serve the purpose of keeping that part of the air filter clean wouldnt it?

No, the metal sleeve doesn't make the air any cleaner. The metal sleeve just channels the air up to that spot. You'd still be getting lots of dirty air.

In the instructions for ARA it tells you to perform the FRA mod.

One side of my air filter turns black at 2500 miles.

Just to give you an idea of how dirty the filter can get, by performing the Free Ram Air modification

well.. i have an aftermarket K&N filter and i think you can wash/rense it and let it dry right? so if its re-usable... does it really matter how many miles before cleansing time? free HP is free HP.. right?
