a buddy of mine gave me a free adaptor, and air filter... but i have no heat shield. and only ideas of how to make it a cold air.. but with just the air filter.. am i better of with the stock cold air?? or should i wait till i get a real cold air filter??

most CAI systems seem to prove worthless on our cars. but if you make a decent heat sheild out of some insulting materials and sheet metal you wont really loose power and your car will sound louder haha

with no heat shield it's not going to be worth anything
it can be an upgrade to the stock airbox but basically only after you've completely built the engine. on mine it's a 5% restriction. on a stock engine it's not going to do anything but sound nice. with no heat shield you will lose power.Comment

ok.. but what if i found a way to pipe it. and have air coming from the front of the car going directly or even better than were it would be placed with a heat shield??? then it would make a difference rite? it would be the coldest air you could get]Comment

The problem with routing it is that all the piping restricts the air flow, once again making it useless. This was gone over thoroughly in another thread about Kamotors intakes. You will not gain any noticeable power by modifying the airbox, similar to the exhaust. Just a different sound for your ears and the "feeling" that you are going faster.-tim

I've been thinking of moving it to the passenger side and routing cold air from the fog light hole. But I am concerned about the extra piping adding a restriction as the above poster says. I'm going to test the much hated high beam delete in a few weeks to see what happens. Probably won't run it like that on the street (looks stupid) but I'm curious to know what actually happens with pressure there..
However, I don't agree that upgrading exhaust or the intake is completely fruitless either. BMW made design compromises in order to make the car sellable to the general public, there is some performance to be had if you are willing to make your own compromises (noise, generally) for a little more power.Comment

I know you can gain a couple here and there with those things, if done correctly, but it is still a small gain. I am referencing street cars/DD's mainly.
As for routing the cone to the fog light, I'd worry that one rainy day it would suck up a large amount of water. On the high beam delete, some say that the headlight area is a low pressure area, but I think it would be better than sitting behind them.
Let us know what you figure out.-tim

i wasn't going to run the filter directly behind the fog light. I was going to run an elbow from the fog light up to the filter which would be behind the passenger headlight in it's own "airbox".
I'll be able to measure the pressure difference directly with the headlight delete. just gotta put it together and make a temp heatshield.Comment

well. im guessing there is a reason for my all e30 guys do the heat shield. and not the custom piping.. so i think it would probably work best that way.. and ill figure out how to pipe cold air to the filter without having to move it from behind the light... but nando update us on how the high beam delete works out. or the piping to the fog light]Comment

most of the E30 guys don't even have a heatsheild!
and I'd blame lazyness over prescience. ;)Comment

i took a lil pipe from sucks 22 degree bend and a velcity stack through the drivers high beam. it works well i have no regrets other than nomore high beams. it looks ok. is kinda loud. i used the stock air box just added a lil pipe to the intake portion.

just make a heatshield and get creative.-Paolo
