Sparkplugs.. Choices, Choices..

[bluephoAm]

So I'm going to change the sparkplugs soon and I found these "splitfire" plugs at Walmart. Splitfire Sparkplugs (http://www.splitfire.com/)

I was wondering if anyone has tried these. It's designed to have a wider spark arc with the "V" design. It looks like a nice deal, too, since you can get a pair of them for about $7.00 over there. Does anyone know what size the gap needs to be just in case these don't come pregapped?

I have heard that split fires are good for the 3.4 liters but when I replaced mine I just changed them out for what ever I could get I cant remember the name but it is the Nascar brand. you may also wanna consider changing the boots while you are in there.

Iridium!
What he said!

I put Ac Delco rapid fire plugs in about 15,000 mi ago and noticed no differance.
I had split firesin my jeep, went to check on them after a few months and part of one of the electrodes was missing. Since then I haven't touched them again.

[FormulaNERD]

i prefer the NGK iridiums...

Dont use them.....i have heard only bad things.

Just hearing that, I won't buy the Splitfires now heheh. Note that my car isn't really for racing or anything, I just like it to run efficiently and, at the same time, surpass factory standards.

I found these: BOSCH Platinum+4 (http://www.boschusa.com/AutoParts/SparkPlugs/PlatinumPlus4/)

I like these because of the unique design and it says that they never need to be regapped so I'll probably get some of these and post a result or something.

[FormulaNERD]

the +4's are a bad idea... a few people on here have had bad expiriences.

You've heard? do you or have you used them? I'm running iridiums now, haven't had any problems?

Bosh double platiums

[Super White Alero]

Get bosch double platium they run for about 10 a pop. Bosch +4 platium are too rich for my blood. And they don't increase your preformance noticibly. NGK are pretty good too and cheaper.

[2000NavyAleroGLS]

I like the Platinums simply because they seem to do the same job but last for a much longer time. Sure they are a little more expensive but I still buy them for the extra 40 or so thousand km.

Denso Iridium's

kinda expensive though, bout $12 a each

[urweak]

The stock AC delco plugs are all a stock/bolt on 2.4 needs. if anyone tells you different they are wrong

[Vtolds]

Everyone keeps saying Iridiums but Iridiums are made for Forced induction/ nitrous motors, so if you dont have a turbo or blower or NOS then you dont need them especially at $12.00 a piece.

[Super White Alero]

Bosch double platium @ your local Auto Zone for $9.95, Bosch Platium +4 are 12.99 and not worth the price. And yea with Bosch, you never haveto gap again.

[bluephoAm]

Alright, sounds good. I've yet to find time to do the maintenance due to college finals and all heheh.

About the V-Power.
Modern lean-burning, fuel efficient engines create a new set of requirements for spark plugs. NGK Spark Plugs answered the call for a spark plug with lower sparking voltage requirements by developing the V-Power, the only spark plug with a v-groove electrode on the market today. Why is this important? The v-groove center electrode on a V-Power spark plug forces the spark to the outer edge of the ground electrode, placing it closer to the air/fuel mixture. What this does is allow the spark to more quickly ignite the mixture, providing more complete combustion.

More complete combustion not only provides more power, it also means less harmful emissions. These emissions are not only damaging to the environment, they can reduce the life of expensive catalytic converters and oxygen sensors. V-Power Spark Plugs also require lower ignition firing voltage, resulting in quicker starts and easier cold weather starts throughout the life of the plugs.

Here are some of the features of this plug:


Triple-Gasket Sealing Process
Virtually eliminates the possibility of combustion gas leakage through the shell. Most other manufacturers only use two seals.
Solid-Copper Core
Produces a more powerful spark with less firing voltage. Other manufacturers use a copper coated center core.
V-Groove
Forces the spark to the outer edge of the ground electrode, placing it closer to the air/fuel mixture. This allows the spark to more quickly ignite the mixture, providing more complete combustion.
Cold-Rolled Threads
For easier removal and installation.
Corrosion Resistant
Zinc Chromate Coating Double-dipped for maximum protection. An NGK exclusive.
Alumina Silicate Insulator
Is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance.
Corrugated Ribs
Eliminate flashover, which can cause misfiring and engine damage, especially in damp environments.

How about these?....Are the NGK V-Power plugs any good? They're MUCH cheaper than the Iridiums but I really don't mind the price of the Iridiums...Just wondering how these compare to others.

STOCK PLUGS ARE ALL YOU NEED!!

I'm with ^^^^^^ does anybody really notice a difference between plugs...I mean a NOTICABLE difference

[bluephoAm]

My girlfriend's brother helped me install some Bosch Platinum 2 sparkplugs today on my 2.4L. It's a good thing that I decided to put some new ones in now. Some of the old plugs were somewhat sooty, the electrodes were almost gone, and the plug on the leftmost side had some rust from some moisture slipping in. It was a real learning experience. There were no wires.. only boots. The only wire plug-in was on the right side (I'm guessing from the distributer). No problems.. so far.. *knocks on wood*

[ilikesubarus]

i like the four point style. they distribute the most dependable spark so it will never miss fire. at least that was my experiance using them

[Fast Eddie]

Plugs.....copper is the hottest, this is a good thing, you want a hot spark for good combustion. anything more than one electrode, like v or +4, is bad, electricity takes the path of least resistence so a large part of the time you are only running with one electrode anyways. Best bet for performance is a set of american copper plugs you want longevity get some platinum OEM spec plugs.
