patanong din,
I've noticed on some cars, may parang heat shield yung sa headers nya, (I'll try to get pix) so nahihiwalay yung header from the radiator kumbaga.
Kung gusto ko gayahin to should I:
a) use something that absorbs the heat, metallic
b) use something that blocks the heat, fiberglass or other insulating material

Iniisip ko B dapat kasi ganyan yung purpose ng header wraps, pero why are the stock heat shields metallic, or meron lang insulating material sa ilalim nun?

magulo ba? :oops: haha
