Guess if it is for waterproof reasons it makes sense. Just have never seen actual proof that these things do anything. Guess it wouldn't hurt if you had to replace your stock one anyway, just seems like an unnecessary mod.

 

Waterproofing and one or two more MPG sounds good to me
Have you ever looked at an 8mm vs a 10mm silicone spark plug wire???

 

What makes it waterproof? Any time you change out an older coil, and older plugs you will see slight gain in power and mpg no matter if you go back with stock stuff or aftermarket. Wires I'm not sure of unless obviously if you have a bad wire. I've always believed that a lot of these companies can make a claim of gained power or mpg because they do see it. But, IMO if they would have installed stock parts (wires and coil) and "regular" plugs they would have seen the same results. Just my .02

 

The heaver wires and boots would be more water resistant not water proof. OEM wires are cheaply made and fall apart easily and I've been shocked through the end of a boot on a pair of duralasts. And yes I was using a plug wire tool when taking off my OEM wires with 1000 miles. And cylinder 3 and 5 between the heat and what nought. And I used dielectric grease and twisted the boot before pulling where the clip in in the plug.

 

I had a srt-10 and everyone on the form hated the stock coils and changed them out with the plug wires.

 

I have no doubts on all of this. Just don't see where all if this increased power and mpg gains are going to come from. Or at least enough to justify changing out equipment that is still good. One mpg and 3-5hp wouldn't be enough to justify, but maybe that is my opinion. Also, if they were that great wouldn't they offer it in print...unless they don't want to be held to facts.

Like someone said, replacing the wires will make a huge difference because old equipment wears out and causes lost performance. If you are replacing already then maybe it's an option.

 

I would totally do it for 1 mpg gain. That's easily over $200 savings per year for me. And I don't even drive it that much. I am skeptical about its promises though.

 

I hear you on that it could go the way of E3s. Just with out the problems of E3s. For 180 bucks for the coil and wires it's worth the try. A engine needs spark fuel and air. With the bigger gap from a .5 to a .65 on the plug it burns the fuel faster and gives a better response. Unlike E3s they do use products like this in race applications.

 

The wires and boots are waterproof for sure simple because, during the manufacturing process, the boot and wire are bonded by a special heat treatment. The connection to the sparkies and the coil, however, are just water resistant, but a little special grease goes a long way :-) This stuff is expensive as hell, but I only use it on my ignition parts and some important fuses.

Iv seen someone else raving about the screaming demon kit on here. I'll be looking forward to seeing results myself.
