I have 66K on my truck and have been thinking about getting new plugs and wires for it. I have started researching the Screamin Demon. What do you guys think about the Screamin Demon? Is it worth the money? If so what kind of plugs and wires should I get along with it?

 

ive heard nothing but good things about the SD coilpack.. i would suggest buying one.. as for plugs n wires.. not really sure

 

I've heard the gains aren't really noticeable. I would only get one if you needed a new coil pack anyway. I ran Motorcraft plugs and the wires from Underdog and they worked great

 

I'm running motorcraft plugs and wires. I agree with Trent if you don't need a new coil why spend the money to get a Screamin Demon. The money you would've spent on that just buy something else for your truck.

 

True... I just figured if the gains were noticeable enough it would be worth buying one. I can not find Motorcraft plugs or wires on the underdog website.

 

I got the screamin deamon and the wires from underdog, then got autolite double platinums for plugs. good stuff. can't say i really notice a difference though. just figured since it wasn't all that much to spend i'd just go for it.

 

i have one and i didnt notice any difference! But its a good coil pack if you want quality

 

dittos on the coil pack. Get Motorcraft plugs. The engine was designed to run on them. Summit has the plugs for like 4 bux. I pd 5-6bux at the dealer.

 

I have the SD, UD wires, and Motorcraft thin-wire plats...It is a great setup. The only reason I really noticed anything was because 1: my original plugs had like prolly 80K on them, and had about that much gap, and 2: I desnorkled my airbox at the same time, so it sounded different.

It is a quality coil, I'd say worth the money. Get Wayne's wires and some Motorcraft plugs, and you'll be set with a good, reliable, consistent setup. Just make sure to gap the plugs at .060 or .065 to get the most out of the hotter coil.

 

I have had good luck with aftermarket coils. I had the MSD packs for my thunderbird with copper plugs gapped at .065 and it made that car. WOT didnt make ANY difference but if your a grandma driver like me and only go half throttle it DOES make a difference. Gas MPG never went up. So, if you want a eye opener buy a bottle or a blower but the screamin demon coil pack will make your truck run better (maybe 10-15HP at certain throttle positions) I wouldnt go huntin down John Force and race the guy though just because you have a new coil pack! LOL

 

i actually just ordered wires and the coil pack from wayne and it should be here monday or tuesday.

i've heard a lot about it, i'm not expecting a gain really at all.

 

i would say you would get a gain of atleast 10hp i would gap the plugs out though.....get the full potential of your coil

 

i doubt 10 hp, you'll see a little gain, but prolly just from fresh plugs and wires.

Def gap your plugs at .060 or .065, or you loose the benefit of the hotter coil.

 

I gapped my plugs to .070 with NGK Iridium Plugs. I felt a difference, a bit more throttle response. Less Groggy

 

whats the price on the demon coil pack?
