I have a intake, and cat-back exhaust. I hope to soon get a superchips tuner. Till i can start saving for the tuner, i wanted to get some small things to prepare for the future. This includes synthetic oil, rework the intake, and spark plugs. Which plugs would best suit my application.

I like the NGK V-Power ZFR6F-11G (6987) plugs. they are the stock heat range but I know you can get them one range cooler but I don't know what the part number is.

The NGK one range cooler plug is the ZFR5F-11 (2262) V-power. That's what I'm running, excellent plugs.

There ya go, somebody with an answer! Thanks Anthony. I had an ulterior motive for posting because I was trying to figure out what the one heat range cooler plug is by NGK. I tried bosch. Sucked. Autolites... Sucked worse. They were dead after 7500 miles. The Autolites when I pulled them out, where the electrode comes out of the insulation in the middle of the plug, it was domed instead of being flat. When they are domed like that the plug has to work harder to creat a spark because it doesn't have an edge to jump from. Yes I actually learned something in my electronics class at school. My old man's got a device that can test the current and spark through a plug and I compared them to the NGk's and wow it was only putting out like half the spark. Plugs are supposed to last a lot longer than 7500 miles. I've had these NGK's in now for 30,000 and they are still running great. I'm gonna get a Superchips tuner myself after I get my taxes back and planned on changing the sparkplugs again to go with the colder ones.

Sorry, didn't mean to :hijack: your thread and right a speech.

The first set of NGK's 2262 I changed was at about 25,000 miles, to my surprise they still looked some what new. They could have gone on a hell of a lot longer.
I change my plugs every 2yrs or 25K-30K miles, they're cheap.

If I find a pic I'll post it.

Andrew,

These plugs wouldn't cause a problem for a near stock or modded motor. Vipers come new with these plugs.

Kenne-Bell known for their supercharger, did massive research and dyno's and stated that these NGK 2262 are an excellent plugs for our Dodge engines

I would agree!!

I'm looking to put a cold air on my dak, are the colder temp plugs a good idea for this? I'm new to mods, so if that's a dumb question please take it easy on me. :help:

Plugs were the first mod I did. Smoothed the motor out some because it idled a little rough from the factory. New plugs gapped correctly means more efficient burn. The cold air intake will help you no matter what you put in first. And no you don't have to have the plugs for the intake.

over the weekend i put in some ngk 2262 plugs and they made a nice difference. smoothed out the idle and it revs smoother also. felt a little power gain but then again my stock plugs were already starting to get rounded off (electrode) and i only have 10k miles on mine. but i think they are pretty good. it does feel stronger now than it does when i bought it. i would highly recommend the ngk v power plugs :biggthump

One more question, Why does everyone put the cooler plugs in? what is the reason for this if dodge tested there 4.7 befor production and came up with the heat range of the plugs.

I just like to know reasons for things LOL.

a colder plug should be a tad more difficult to send a spark.... so for people that have a lot of performance parts and computer chips and what not like to have a colder plug in fear of the motor pinging, which means detonating before it should.
