Underhood temps go up.

Not that much. It's a stock cast iron header. Aftermarket SS or mild steel headers with no heat shields will transfer much more heat, resulting in higher underhood temperatures. I really think that the stock heat shield is to conceal the ugly cast iron manifold and protect fingers when checking the oil.

But compared to not having it on there the temps will be higher. Stock versus stock without heat shield, without the heat shield, the temps would be higher.

and like i said, when you install an aftermarket header, you don't reinstall the heat shield. right? an really how much more heat can it produce anyway? i could understand if it was 200 degrees, but its probably more like 20?ish.

 

The argument was not whether or not he should put a heat shield on an aftermarket header, but whether or not he should take his off a stock header. I say he should not, not only is the stock header ugly as sin, but it would cause the underhood temps to go up, (how much they go up, I couldn't tell you) but when I put my aftermarket header on, without the heat shield, underhood temps where noticeably hotter.

 

i do agree that they are ugly, but does the extra heat actually hurt anything? or is it just more of a precaution type of thing? if its precaution i say let him gloat his ugly manifold. if it would hurt something, then i would agree to say no keep it on. but......its his choice i guess.

It might not hurt per se, but it doesn't help anything. You want to keep the engine temps as low as possible (but not too low), heat is what destroys stuff.

 

How hot do you honestly think your engine bay gets when you're shoving air into it through the bumper at like 40mph+

Weight Reduction!

 

you should leave the heatshield on, engine bay temp goes up forcing hotter air into your intake decreasing power and increasing wear... aftermarket headers are better suited w/out a heat shield since they're made of higher quality material with power in mind...

 

not with cai it wont.

 

theres no reason to do it with a stock header. the weight reduction wont do anything, and the added heat to your engine bay wont make your engine run any better, and will propably dammage the paint on your hood over time.

It will heat up the piping more and thus by induction, heat up the incoming air...

Dont think that the difference is going to be that great. True, the incoming air is going to be a little hotter than before, but at the same time, a CAI (or any kind of intake piping) is going to heat soak and have the same problem. It wont matter either way. Also, has anyone ever seen the difference in horsepower caused by an intake charge that's say 5*F warmer or colder...?? The difference really isn't that great

I wouldn't take it off because it wouldn't be there for no reason, if it's there it's there for some reason so just tell him to leave it alone unless he plans to get a header.

 

i vote, leave it in

take off heat shield only if your installing a new header.

the heat shield is there for a reason, or honda would not have put one there.

plus its extra work to take it off and have ZERO gains out of doing what your doing.

leave it alone, if you have nothing to do, stick in some leds in various places, like all the other cats in the forum hahah.
