I can't search the archives - server down? Anyway, I have heard folks mention sleeves or tape or something that you can put on you plug wires to prevent them from melting on the headers. I just installed a set of TES headers and a set Made4U wire looms (very nice finished look with these), and I fear that the at least some of the plug wires are going to find their way over to nestle up to a header tube once the engine starts moving around!

Anyone seen/used/heard of something like this?

I use the Spectre sleeving. Comes in different colors. It's rated for up to 1400*, which headers don't get much hotter than 1200* I believe. They're 12.99 for 10'. I only bought one package, and ran short about 3 wires, so just order 2.
There are other brands that I am are better, but that gets around $60-$80.

They also have high temp boot sleeves, but I would think you could use it on the whole wire, about $35 for 1 ft. rather pricey, but stands temps up to 2300*. Just do a search on www.jegs.com for braided plug wire insulation.
Here's a pic of how they look, unfinished though.

 

The MFYs are gonna be bad news with the edelcrock headers, at least on the passenger side. The only effective way i ever found to route the p-side wires on my old camaro with those headers was to run all 4 wires all the way to the front of the engine, then back under the headers.

 

i have a set of nomex sleeves on my wires now, not very attractive but they sure do work

 

yeah, the passenger side is the real problem. Further complicated by the stupid AIR tubes. What about wrapping some exhaust tape around the wires as they pass next to the headers?

 

The easiest and cheapest way i could figure out was to use Zip-Ties. I know it sounds ghetto, but it keeps the wires off of the headers for less.

 

Don't do that. I had done that too, but this causes arcing.

I also bought the MSD wire separators.

After burning 3 plugs, I went all out to ensure safety.

 

How can zipties cause arcing? I've been using them for years without any problems. You can't just put one tie around all of them, though. Use them to separate them and it should be fine.

 

I'm just going through this at the moment. I've routed my wires in the stock location, or under the manifolds. I have proper Moroso seperators (2,3 and 4 wire holders) It is trickier going this route but I wondered about using cable ties. Do they have to be special ones becuase of the heat from the block?

It is a work of art and if you get it right it is satisfying in the highest degree

 

The zipties will cause arcing if you tie a bundle of wires together against something like the AC bracket. If you keep the wires seperate from each other and spaced off of whatever you're anchoring the wire to, you won't have that problem.

DEI makes some nice heat-shielding products. In addition to what I have now, I'll be getting their heat reflective tape for the fuel and brake lines, another starter wrap for the master cylinder, and some more sleeving for misc. wires.

 

Of course if you also use zip ties to separate them, they'll be fine. I just thought you just zip tied them to each other with no spacing. sorry for the confusion, I just didn't want anyone making the same mistake I did.

 

I zip tied 4 together..I have Accell 8.8 wires, no arcing but I think I will seperate them.

 

I had no idea that would occur! I'm still not entirely sure how that's possible either. Can someone explain how 4 together causes arcing??

 

It only takes 2 together to arc. The current in them can attract each other. This is especially bad in 5 and 7 cylinders, since they fire right after each other.
