    Hood insulation

    OK that foam hood insulation crap is falling apart due to it's life in the Texas heat. Aside from ordering it from an aftermarket supplier like Pelican---are there less expensive alternatives?

    theres no really cheap alternatives that will last or withstand the heat. i got the 3 piece foam with aluminum layer from bmp design for 80 bucks about 6 months ago. i cut the hole out for the throttle body, and covered it with aluminum tape btw

    bav auto has the OE black foam kind for 60 bucks, but its crappy and will crumble again in a few years

    Is the BMP one self adhesive, or do you need to use contact cement? I need to do something about mine soon.

    nope, its not self adhesive. i just used epoxy and it held it very well. although you can see in the pic i posted i did a very crappy job and the epoxy dripped out. i should have removed the hood before installing it, but i was too lazy

    Well, I took mine off of the FC, and now when it rains, I have steam coming up off of the hood.

    i believe most, if not all had them, but after the years of heat and oil and dirt and grime, it just kinda crumbles and owners scrape it off. it certainly cools it down, and dissipates the heat. its not necessary, but i like to believe it was put on for a reason

    Why not switch to the fiber liner?

    Easily removed, and generally unnecessary. It's to quiet the engine noise, not shield heat. You really want the engine bay hotter?
