hey there, i was just wonder if it is worth buying a heat shield for my cold air intake. Im not sure what are the pros and cons of having/installing one onto my KA24e . . . it would be great if i could get your opinion


Thnx

 

it might lower the air temp some but i'd say it's not worth it. just do the tb bypass.

 

Its def not worth it.

 

The air is moving so fast through the intake (remember, 2.4L of air per revolution) that heat shielding won't make any difference. I also argue that CAIs (in a street application) really don't do much good either. You get better performance simply from an unobstructed air path.

 

so another word it defeats the idea of having better performace?

 

I don't quite understand your statement/question.

 

i agree to an extent. but with a cai the piping also is cooled and therefore reducing the incoming air temp slightly. the the idea with a cai is to get air from outside of the engine bay.

 

Heat shielding doesn't do a whole lot, and in some cases it can create flow problems.

 

What brand of CAI do you have that has cooled piping?

If someone really had the time, they'd work on a cowl-induction system and really show gains with the higher density/lower pressure (physically cooler than under the bumper) air at the base of the windshield. Chevelle anyone?

 

The best way to get more cold air is to build a custom cold air intake. If you looking at the motor from the front (after opening the hood) you notice that the piping goes over the radiator and to the right where the air box sits. Biggest downside is that the heat from the radiator warms up the piping.

To avoid this (but not recommended to be used in CA) build a cold air intake that will mount the cone filter on the left side. Yes you will have to relocate the battery to the rear of the car, but hey, thats a good thing. But in this sense, your piping stays on the same side as the intake manifold. If your worried about cooling issues within the engine bay then, just build a vent system to bring in cooler air into that section of the engine bay. Heat shields are over rated, use them heat wraps for the downpipes and exhausts insetad! LOL

 

it's not that any brand has cooled piping but the surge of incoming cooler air will cool the piping. it's not really any thing special but the tb bypass world on the same principle and it yields noticeable results.
