im about to do a good tune up on my car,,


i was wondering what is the best spark plugs and wires and coil pack for my car
thanks chris

 

i wouldnt bother getting platinum or multi-tip plugs, you're average $.89 plugs do excellently.

 

okay thanks what about wires

 

ive always liked accel u groove plugs/and bocsh platnumis just the reg ones though like 99 cents each

 

if u know how to crimp the ends on urself get a set of accell custom fit wires( u have to cut them to lenght and put the ends on urself though, better then stock replacements and not much more exspensive prolly like 10$ more depending were u get them from

 

I've had more of the accel make your own wires go bad on me then I care to count.

I've had decent luck with taylor wires.
Would like to try some msd wires.


I run acdelco basic plugs at recommended gap.

 

IMO: Run stock replacement-type copper electrode plugs....preferable AC Delco or an the Accel u-grooves like mentioned earlier, or NGK's which are excellent plugs. Avoid Bosch plugs, dont seem to do well in domestics in my experience. And avoid platinums, double or quadruple ground electrode plugs, and most other gimmicks.

Wires, I had great luck with Taylors on my old six....I was very surprised with the quality for the price. Very nice wires, well-made, and relatively inexpensive for a "performance wire". If you dont want to go so hot, you can get Bosch wires or a like-brand, with a lifetime warranty....so if you f---- up a boot taking one off, you can get them exchanged for FREE. Well worth it, trust me on this.

Coils.....ehh. MSD usually makes good stuff for a fair price. I believe they have a stock replacement Blaster coil for you f-bod guys. Accel makes em too, cant say I trust Accel but hey....it's still aftermarket. Hypertech makes a coil also, I hear very good things about it. Almost installed it onto my V6 but I ended up selling it rather suddenly, and canceled my order so I never got to see it or test it.

 

Gotta be careful with newer plugs. They have made some good changes but they are not good for all Ign systems.

Something about using small dia cores that work well with new cars but not the older systems.

Ill re-post info here.

"Dave-
Any benefit from using platinum plugs, or double platinum plugs?

I see they have a very small diameter electrode... supposed to do something to lower the voltage required to fire...

all the modern cars use them, it seems like, with the modern ignition...

Jim"


"Nope, Does your engine run at nuclear temps, emissions lean as a popcorn fart?
If not, don't waste the fundage on any small electrode plug.

NGK started the small electrode plugs, for one good reason, damage control. The small electrode is there to melt into a mushroom shape when situations in combustion chambers are adverse, instead of killing vital engine parts."

That from Dave Ray of small body HEIs, he build Ign system for all the top racers. Has a 6month backlog if you want him to build you one.

[One tip he pushes on everyone hard. Epoxy filled coils are all junk. ONly oil filled coil are reliable for racing. Epoxy holds in heat, not displace it.]

 

Lots of opinions in here.

Since this question is about as loaded as "tastes great" OR "less filling" it's all pretty pointless. The only reason I'm contributing is to share my personal findings with my 91 3.1.

When I got the car 5 years ago, I installed stock replacement Delco plugs. The car wouldn't run. Three sets of plugs later I installed Bosch platinums. I fiddled with the AC plugs for about 6 months, fighting dead cylinders, misfiring, etc. After the Bosch plugs I went for 3 years of daily driving without a single spark related issue.

Last summer I decided to install a new set of plugs. I went with a set of NGK V-powers. The car ran great... till the temp dropped. The first 20* evening the car died at work, wouldn't fire on more than one or two cylinders. After a trip to the parts store and installing 3 of the Bosch platinum plugs the car ran well enough to drive it home. The next day I installed the other 3 and I've been driving it every day since then.

I'm not saying that every 3.1 will react this way, only that mine does. It simply doesn't like AC Delco or NGK V-powers. Could be excessive blowby fouling the plugs, could be crappy gas I'm using, I don't know. What I do know is that the platinum plugs aren't much more expensive and they work in my application.

The notion of a required regular tune up that entails replacing everything under the hood, as is typically advocated on this board, is rarely necessary. If your car is running on all 6 cylinders, and gets 15-17mpg around town, then you're just going to spend money and spin your wheels chasing any improvement that plugs, wires, and a coil can give you.

 

Two things Ford did well-

1) 9" rearends
2) Autolite sparkplugs

Don't use the platinum plugs on your engine especially with a hot coil- They burn up- Use good old standard Autolite plugs, They are workhorses with very strong large electrodes-compare them sometime. They are the only plug that lasts on my racecar.
