Hood Insulation

[JIMBOX]

Thanks NHJLUR-

It's kinda obvious too, as far as insulation uses/needs-

Have a great day

It also prevents the Engine Heat from screwing up your hoods Paint after years of use.

A slightly less known benefit from those mats is in the event of an engine fire, they help smother the flames...in theory. They are hit and miss

Ima be cutting mine open this week.. will document it in video

Thanks! Actually I pulled it to throw a hood decal on (had to get the hood bumpers/sprayers off). Easy enough to put back on. I was just being lazy. Do like the paint, and don't like flooded engines, so I'm thinking putting it back in place is a no brainer...

I'm going to be doing the same for the same reason. Any tips for removing the insulation or the bumpers?

Why they gave Rubi's rice from the factory (non functioning vents) is beyond me

Just cut the opening up of the insulation and the bottom of the vents out and you're set

Sorry if this is asked and answered, but the black insulation under the hood... do we really need that junk? Is the sound dampening really worth it? Or does it make a difference in preventing overheating (I'd think the opposite).

Full disclosure: I just pulled it for a mod, and broke half the lil black plastic tacks. I really don't want to bother putting it back in... :cwl:

The insulator is more than just that.

It protects hood from heat, the engine from water and the functional vents were designed to work with it.

The small holes in the hood vents create greater vaccuum than if they were open/larger holes.

A larger hole for the vent would create a tumbling effect of air. The small hole creates a strong streamlined vaccuum of exhaust.

Sorry that would actually create less vaccuum.

The small holes in the vents were designed to work WITH the hood isolator.

Open up the hole size in the vent and you will create a tumbling effect of air.

The small hole creates a strong streamlined vent/exhausting of air.

Ever been in a smokey car? Crack the window just a little and you'll see all the smoke get vented right out pretty quickly.

Roll the window dow all the way and the smoke will "tumble" in the cabin and actually take longer to vent.

Simple science actually

I meant cut out the bottom completely instead of little holes, like stock vents but without the bottom part and then where the insulation would be, cut that part too

Just figure why buy Spyder vents when you can diy

I’ve been curious about putting my hood insulation back in but now that I have extra plastic rivets that the hood needs for it I’ll cut my insulation to support my hood louver.

Only quake I get is when I have the hood up and the wind is catching it.

Hi Ross. I have removed about everyone of those brittle "potato chips" from all my vehicles. They are for sound insulation and have nothing to do with deflecting heat as some on here indicate. I included a couple of photos of what I did to reroute the water. Basically a couple of 1/4" plastic elbows, a couple of pieces of plexiglass to cover the slots and some clear tubing I had laying around. Insert the clear hose in the rubber seal on both sides of the hood (hollow rubber tube) and the water drains to the back of the front fender. Works great.

Additionally I cut out the sides (leave at least 1/4" from the bottom) to help the heat escape which works quite well.

Anyway, give it a look and congratulations for getting rid of that .10 junk pad!

Doesn't have a thing to do with engine heat and paint problems. Most muscle cars never had an insulation pad. I've had several Jeeps that didn't have any either.

It's for sound insulation and in the JL's case, provides drainage channels for the fake air vents.

@JEEPIDON That is a clean install and great idea. Give the water a place to drain AND the heat escape. I was going to saw to hell with the water issue, but after seeing this i may have to copy your idea.
