Anyone know if it's ok to remove the hood liner? Seems like having all that insulation might make the engine bay area warmer than it has to be...

its obviously there for a reason... i believe that if u take it off... the engine will heat up the hood, and ruin the paint, and maybe cause a fire...??? i'd just leave it there!

Really?? The engine will put that much heat onto the hood?? It seems like if it put THAT much heat on the hood...the liner might get hot enough to catch on fire.

sorry cruzin...i have to blow a big fat BULL $*** horn there...

i have had my hood liner off for over four months and have had not one single crack or problem since!

the hood has not even become very hot to the touch, and i drive more than most like a madman. i dont see why there would be any problems with it and i live in hot weathered sunny californa. dont worry your paint.

dont worry about the liner, its not gonna damage your hood

OK good, do you think removing it might even keep the engine bay cooler??

i believe the hoodliner does serve a type of purpose, im not exactly sure of it, but it probably does a number of things like...
absorb moisture
keep in enough heat during the cold winter months
engine noise/rattling reduction
contains an engine bay fire?
prevents rusting? (has to do with absorbing moisture i guess)

theres more reasons to keep it than take it out

you want to run the engine at an optimum temperature, not at a temperature thats as cold as you can get it (if that makes sense). if bmw knew that the engine ran better at say 180 degrees than 200, then theyd reengineer it, maybe taking the headliner out, but the engine runs best when its right in the middle of the gauge not when its cold

i dont think you would even feel a difference in tempature without the liner... its there to keep the noise of the engine down... and maybe keep the engine warm in cold tempature

it had the same replies that we have here....mixed emotions.

basically there are alot of good things in keepin it. i pulled mine cuz it was ripped and crusty.

i have had not one single problem and the noise difference is nothing remarkable but i love the way the engine sounds so im in favor of the remoal.

the point @ cold weather seems very good, i live in so cal so no worries there. in cold areas its probably a good thing to have.

it did weigh in around 6-8 pounds, not much but every bit helps.

as for heat, my car is black soooooo.... im no help there my hoods always really warm but the paint IS JUST FINE.

yeah, there have been some discussions in the forum about the hoodliner. It is there mostly for engine noise reduction. The hood still heats up none the less due to sun/hot weather and the material isn't a heat deflecting material anyway. I don't think it would be a good idea to deflect heat back into the engine anyway, cause isn't it the idea to keep engines as cool as possible? It would seem that dissapating heat away from the engine through the hood would be a good idea, but thats just from a physics standpoint....

Paint is suppose to be able to stand up to the heat created by the atmosphere and the car itself, otherwise a lot of other cars would have some killer paint problems. I know plenty of cars that don't have any kind of liner like BMWs.

Taking it off though really won't make much of a difference with anything, except perhaps 5 lbs of weight reductions, which is still like no big deal...

just my ideas fellas...
