New "cold air" intake... what a difference!

[Jason]

After having the cone filter stuck on the turbo over the winter, I noticed now that it has gotten hot and I have the rad fan back on, the hot side of the intercooler was really hot... Turbo lag had gotten worse as well. With the engine running, the fan pretty much blew hot air directly at the turbo and cone filter. Not the best setup.

So, I used one of my left over pieces of 3" tubing, and moved the cone filter over behind the headlight. I fabbed up a "box" for it with some sheet metal, painted it silver and topped it off with some door edge protector so it looks half way finnished and wont cut the crap outa me! I also removed a plug that was in the body just below the headlight, which opened up another 2-1/2" hole to the front of the car for more cool air. The results are impressive. The hot side temp of the intercooler after driving around is MUCH cooler, just warm to the touch rather than hot. With the lower inlet temp, the output side of the intercooler is actually slightly cold now, even in 80 degree weather. Overall well worth doing if you have an open element filter, I think the box around it really makes a difference.

Lower airflow capacity that the stock box? Do you know what it looked like? The inlet from the fenderwell was tiny. Its not the nicest filter around, but it is a dual cone with an inverted inner cone. It flows quite well. A larger paper element filter is on its way to replace it anyway.

Its a heck of alot more than a tiny cone! Paper filters have far more surface area than screen-door type oiled filters.

It wasn't so much the filter itself, more that the box it was in was a restrictive design. Dont worry, I replaced it with a MUCH larger paper filter thats for a heavy equipment application. I'll post up a pick shortly. There is NO lack of airflow now.
