I've come to the point where I'm going to be switching out my spark plugs. I've heard before the stock ford coil pack is the best. I'm not needing a new one, just more info for the future.

1. state your recommendation

2. which do you actually have?

3. name any you have had a bad experience with.

I am running Motorcraft (Ford) coil pack and work great IMO. I have heard everyone with bad experience using Screaming Demon coil packs so I would stay away from that. I use Autolite copper plugs in my car. I would never buy anything more expensive than regular platinums in either Motorcraft or the Autolites. I believe the factory plugs I pulled from my sixer were Motorcraft Platinums. Stay the hell away from Champions. Also steer clear of AC Delco (they are chevy plugs) and Bosch (they work well in older cars but have never had good luck with them in newer vehicles)

[mustangmike!]

Motorcraft has Ford's name behind it, its a name I trust, as do many others.

Coil packs are iffy, everyone ive ever seen has recommended to buy an Ford coil pack. Will probably pay more cause of the name, but they seem to be the best. I am currently running a Borg Warner coil pack w/o problems, but only put a couple thousand miles on it, so idk how long it will hold up.

I also agree w/ the above statement on spark plugs, Motorcraft or Autolites; Coppers.
I am running the auto's as of now for about 6k miles w/o problems.

Same, Motorcraft all. Copper plugs provide more efficient spark but do not last as long as Platinums (which is what comes factory). Most will say copper plugs anyhow.

[6ER THEN I 8ER!]

copper plugs and any coil pack but a screamin demon lol

[mcqueen]

Motorcraft or Autolite copper plugs and an oem coil pack. I've run NGK platinums in my old V6, they performed like shit. Coppers run much better.

[WhiteShadow]

well the only motorcrafts near me are platinums. so itll do!

I just put copper NGK V power in my v6 3.8 last week and man o man does it run like a champ! Excellent throttle response and MPG. When I hit the pedal, my car instantly responds. Sounds and idles better now. I can feel the power now, no joke. It did take a few miles for my car to adjust to them

They cost $2 each

I always think it's crazy when I read spark plug reviews like this. Compared to platinums or iridiums, copper plugs will run much better in our engines. But if everyone just left coppers in their engines the whole time (and changed them when they're supposed to) then everyone would understand that their engine running so well on coppers is how the engine is supposed to run. "Better" plugs will not gain any power, will not increase mpg, etc. Running shitty plugs will hurt those things, but running the proper plugs will have your engine running like it's supposed to be running, not better.

True True...

But I used many spark plugs different cars. I'm a firm believer that some spark plugs do give you better throttle and engine response then others. Ac Delcos Rapid Fires in Chevy engines does make a difference. I swapped some in drove around took them out and put regular spark plugs in and drove around. The rapid fires were a lot freaking better then the regular plugs. The rapid fires did have better throttle and engine response. This was on a 85 Chevy 350.

So yes based on my testing, better spark plugs does give you better throttle/engine response then others. And better spark plugs will give you top MPG then others . Top MPG not more MPG's.


But all in all the NGK V Power Coppers runs good in my car and I love them. Good throttle/engine response. I can tell a spark plug that actually does something performance wise

I'm not saying they give 100hp and 100 extra gas mph. but some really do give a little bit of performance.

Peace

exactly....i cannot understand how some people think the way they do

[goren813]

They feel a difference because the plugs they removed had 80k on them. Clearly. Dumb posts = headache.

lol good point

[BluV6]

Im surprised no ones mentioned E3's? My brother and I use these in every vehicle we've owned (including my parents vehicles) and they have been nothing short of amazing ( for spark plugs anyway). They deliver a more powerful, hotter, and concentrated spark. They give you better throttle response, low end torque, and improve your mpg by 10-20%. And they're proven in lab results and out preform any other spark plugs out there.

My buddy tired some in his Probe GT, with the E3s he had to turn the boost down to 12psi or he would blow out spark, so he put his NGK V-powers back in and set the boost back to 16psi. They may be proven to out preform other sparks plugs on one engine, but they certainly don't out preform other sparks plugs on all engines. I also have to wonder what spark plug they compared it to to get a 20% increase in fuel economy as there should never be a difference that large if the engine was running correctly for both tests.

[BluV6]

Who boosts a Probe?, honestly, its a Freakin probe, and 15 psi is to much boost for any engine that isnt fully built from the bottom end up, and also were not talking about modified engines here, were talking about stock engines which is what E3 warranted their spark plugs for, and my brother put e3s in both his trucks and his mpg went from 10 to 12 which to my calculations is 20%.

[nicksranger01]

I would stick with Motorcraft and DO NOT PUT E3s IN TO YOUR FORD, that being said i had them in my Ranger for 4 months and the truck started to miss changed the coil and still had it, pulled the plugs and 3 out of the 6 were fouled for no dang reason, put motorcraft back in and bam perfect that was 6 months ago

Do your research before you speak, Ford boosted 89-92 Probe GTs from the factory, that's what made them GTs. They had hypereutetic pistons, and forged rods that handle plenty of power so yes the bottom ends were built well. I'm hardly taking about a modified engine, a cold air intake, an exhaust, and a boost controller is hardly anything.

There are plenty of Probes running around at 300whp, and a few pushing 500whp, they're nice cars with little aftermarket support so when you see a nice one you know the owner is a fabricator and did the work them self, not every one like cars you can build with a credit card, some people like to build things rather then buy them.

[BluV6]

if your plugs are fouling up that means your running too rich and that will happen to any spark plug, and who gives a shit about probes the last time I checked this was a mustang forum, and the 89-92 probes only produced 7 psi of boost and if your friend is running more than that then he modified his car, which like i said is not covered by my E3's warranty, i'm talking about stock engines here.

i put E3's in mine and it still runs fine.
