Actually, some open air 'performance' filters have shown to reduce hp because they suck in hot air from within the engine compartment. The stock CSVT one flows less but brings in cooler air from the wheel well.

IF you get one of these, a heat shield is a must. I made one for the webbers on the summer car. Before the shield you couldn't put your hand on them after driving, and once or twice I had fuel boiling in the fuel rail...now you can lay your hand flat on them after an hour of hard driving.

You made a heat shield yourself? How? Did you put it in the "How to" section?

I would be interested in a "How to" if you have a minute, or can direct me to one.

Thanks !

Actually the one I made was for the z. I made it out of aluminium. Just a single piece with a few bends in it, fastened to the side of the engine compartment.

I am still running the stock one for the contour. I think there are others on the board who have fabricated heat shields for their contours/mystiques that consist of a bent piece of aluminium with a rubber seal strip along the top that sits flush with the hood.

Black plastic trash can and foam pipe inslulation. Total cost: $5. Definately use something plastic, as a metal heatshield will not block the heat as well.

Does anybody have any *actual* dyno's of just the stock svt baffle vs a cai ?

From what I know, the stock svt intake is lifted from a previous Cobra -- if it can feed a 5.0 hi-po, it can definately feed the 2.5.

Ignorance speaking maybe. But couldn't plastic melt? Or is it not quite that hot ? What type of plastic did you use?

Thanks, that is an interesting idea.

No, the plastic will be fine. Like others said, there is tons of plastic under the hood. I made mine out of alum. for my other car because the carbs sit directly above the headers, so the heat flows upward right into the filters. You'll be fine with plastic.
