plastic intake mani
Just installed a cai on my 01 LX. The intake manifold caught my eye. It appears to be made of plastic or some sort of composite. 
Has anyone found a performance intake mani that will help the little D17 breathe better?

If you had a metal intake manifold, it would heat up along with everything else in the engine bay, thus increasing the temperature of the air going into the engine.
The plastic intake manifold doesn't heat up as fast or as much.

For the D17 at least.

Someone made their own aluminum IM and it performed better than stock. Gained alot more torque and some hp, but cost over 1k. He had equipment and materials tho.

Rep Power: 0 OK, if plastic is better, then why aren't we seeing performance plastic intake mani's? Earlier I read a post that said a modified b16 intake mani would fit. Anyone heard anything like that.

Rep Power: 812 A metal manifold will heat up much faster and hotter because it touches the head. It's just better technology I guess to use plastic. Still don't know why there's HOT coolant running through the TB.
