wrapping the headers like showed above might be worth a thought WHEN they crack and the replacement effort has to be made. (for me at least)

wondering though if wrapping the headers might mess things up?:
if wrapped to tightly for sure the expansion characteristics of the headers change ... more and different cracks?
I have seen somewhere a header heat shield which is more like "socks" or "bags" or so to keep only a loose contact with the headers and still encapsulate them... EXPENSIVE

You do know the antenna can be mounted on the roll bar, under the zippered cover and will pick up signal just fine with a hard or soft top, right?

I assume adding vents would help an issue I'm having. When on a long trip on the highway on a hot day, my A/C feels cold but even with the blower turned all the way up it's hardly blowing any air out (like it's on low). I have assumed the engine is running too hot and the computer (?) cuts the A/C for that reason? The A/C later returns to normal.

i used perforated metal from mcmaster. someone in my club coined them "stealth vents"



while they did not make a dramatic difference in engine temp, the underhood temp was reduced. i was melting all sort of stuff underneath and since i put in the hood vents it has been relatively cool in the engine bay.

^^^ details on how you cut the holes. I have thought of doing that, but was afraid I couldn't make the holes that pretty...

i used a step drill to make the corners and then a metal shear for the sides. (use plenty of painters tape to protect the metal) that way it stayed cool and i only had to paint the cut edge. hardest part was measuring 15 times so i didn't screw it up.

Installing mine today (between 2 and 4am I guess), I am planning on symmetry therefore my rear driver and passenger (Genright 3pc long black) will be moved a little more forward just so the pass louver isnt directly over battery terminals or fuse box. Will post pics during and after
To the guys that wrapped their manifolds and whatnot... I have read that over time moisture (rain,washing) will soak the wraps and it ends up rusting the wrapped piece in 10x the time, have yall checked them lately to confrim or deny?

With a deep understanding of this particular topic, YES THEY WORK, assuming they're done correctly.

I have accurate intake temp data logs to prove as well as a dyno-sheet showing a 7-10whp gain.

****************************

Also to the guy above who went to mcmaster carr to get that aluminum sheet, I went to the same place when I first vented my own sports car hood. I used a snap-on brand air saw to cut the holes and found a clever way to attach them without using any screws etc. Also I can show you how to build slip on cover that needs no holes to help with muddy days if you wish your engine compartment to stay clean. Rain is no worry, even in Seattle where I lived prior.

But don't place them too forward though. You don't want water going in the air intake . BTW water will not harm your fuse because they covered up.

If you read the first few posts here you would see pictures showing the hot spots under the hood. You should stick to that when placing those vents.
