Has anyone used one of the header insulating wraps? I just got my header in and was wondering if its something I should do before I install it, I was also thinking about wrapping all the way through the downpipe to the cat to lower my underhood temps a little more. Any feedback is greatly appreciated.

I asked this same question a while back when I put my APN header on and was told it wasn't necessary. I went ahead and installed it without the wrap and there was no change in operating temperature from before. So I'd go ahead and say it isn't necessary.

What header did you get?

Apn from amazon lol, I don't expect a change in temps from stock to the aftermarket just want to cut them down even if I was to go with the stock one again I'd think about wrapping it but I'm weird like that overkill over underkill.

I know from my days of working on the older V8 engines that most header companies will void header warranties if you use header wrap. Hooker,and Headman, just to name a couple.

Not worried about warranties, if it breaks in a year or two I upgrade again something better, just trying to cut temps as much as possible since our exhaust and intake system are all on the same side of the engine bay every little bit helps

The other option would be to get one that has a ceramic coating. You can have them sent out. One company that does it is Jet hot or Jet coat.

The company is Jet Hot

If your engine leaks oil, even a tiny bit...don't wrap the headers unless you like engine fires.
The ceramic coating is a much better option.

Gee oh Dee

Also the wrap tends to hold dirt and moisture, causing corrosion early.

Actually I have no oil leaks at all (knock on wood)

Rain. Mud. Offroading.

Daily driver no offroading, doesn't rain that bad in ct, no dirt roads so no mud really

Radi

you already bought the wrap, didn't you.

partsguyct

No not yet, don't get paid til the 14th lol if I don't wrap I'm just gonna paint it along with the intake

ZINGGG

All valid points. Don't wrap it.
