Default Header Wrap

Whats everyones feelings on header wrap? What are the benefits? I want to wrap mine but I am not sure if the benefit is worth the trouble. I would like to save my plug wires and also reduce the under hood temps. I am going to order 2 sparkarms to extend # 1 and 3 sparkplug wires to get them away form the headers. Norval did a writeup on these a while back so I thought I would try them.

Why not use some plug boot protectors? Headerwrap works very well, just put it in a bucket of water so it's thoroughly wet, wrap it on tight and fire up the engine. It'll shrink and pull super tight.

Those spark arms...they look so silly IMO, I'd rather waste my money on some jacobs ceramic boots.

didn't know about wetting it, will have to try it if I install the wrap. Norval had boot protectors on his and the boots were still burning. The large primary pipes are just to big to get any clearance around them for the plug boots. Norval also has his headers wrapped but was still having issues. Had not seen the Jacobs ceramic boot wires before, may have to look into them to.

I wrapped mine & sprayed 'em with silicone paint. I like it--underhood temps are lower and I no longer get third degree burns checking oil & the like. So what if it does reduce the life of the headers a little bit? They're cheap. A friend had his ceramic coated--Yeah it looks really pretty but I can't say it made a big difference in his underhood temps, and they stay hot a lot longer. I can grab a tube less than 5 minutes after turning the engine off.

Got any pics? What is silicone paint? It would be nice to paint them.

The silicone paint is to waterseal the fabric so it doesn't absorb & hold moisture which would increase the speed of rust forming on the tubes. I used silver, it also comes in black and maybe other colors.

No pics, it just looks like wrapped headers......

You need to wet it at installation to make it soft & pliable to form to the curves of the pipes. When it dries, it stiffens up a bit but keeps the shape.

Thanks I have to find some silicone paint. I may pull them off this weekend and give it a try.

I was going to header wrap my headers to cool down the under hood temps. Broke the engine in without and shot header pipe temps with an IR gun after 30 mins. Pipe temps were in the low 700 degree range. I then opted for Jet Hot ceramic coated headers and ran the engine under the same conditions.. header pipe temps were in the low 300 degree range. I know this might be a litle off topic but IMHO the cost of Jet Hot coating is not that much and the benefits, at least to me are far superior to header wrap.

Interesting. I didn't think it would make that much difference, in spite of their advertising. I'll see if I can get a temp reading on mine tonite for a comparison.


Here's a shot of mine, as I said, not much to see....
