Spark Plugs (for cars and trucks)

[warlord]

Hey everyone. I just put some new champion plugs in my sunbird and it runs better and gets better mileage. Only problem is that it doesn't idle too well now. It doesn't stall or anything, its just a bit rough. Anyways, thoes plugs were cheap as hell so I don't care if I wasted my money on them. What I want to ask is, do any of you have any experience with the high end plugs like ngk iridium and those fancy bosch ones and such? Are they worth all of that extra money or are they all hype?

All I have is fords so I only use motorcraft plugs and wires. On other stuff it don't matter but on mine when I've used bosch platinum or anything, they'd be skipping in a couple of months. Most of the platinum plugs have very little electrodes(I think that is what they're called) and I've talked to several mechanics who say they are junk.

Did you check the gap on the plugs? I know most places will say "they're already gapped", but don't listen to them. Wherever you buy your plugs, have them look up the gap and then check it when you install em. I have yet to buy and set and HALF of em be gapped correctly.

They're probably not gapped right. It would be worth it to get some slightly higher-end ones. Not like the 10 dollar ones, but something like NGK V-power or NGK Platinums. When I switched from the cheap 1.29 autolites to the NGK Platinums (like $2.70 each) and NGK wires the car ran better. It idled smoother, started quicker, and was actually a few mpg better on gas too. The escort was a dohc though, which has a tendency to be pickier about what components you use with it, so you might not get the same results with your 2.2, which is a pretty mild engine. But then again, if the new plugs made it idle hard then better plugs might make a pretty big difference.

Mines a 3.1, still not a high tech motor. I had a hell of a time getting the 3 rear plugs out and the new ones back in. I checked the gap and its supposed to be .45 I think and my tool only reads to .39, so I adjusted them to be a little bit loose on the .39

don't use bosch platniums or champions. the bosch plugs tend to get stuck in aluminum heads (which 3.1s have) and champions are not a very good plug. I've always prefered delco plugs for GM cars. If you want OEM performance, use OEM parts.

ANY steel spark plug(and they ALL are Steel) will freeze in an Aluminum head UNLESS you anti-sieze them.

Much like the StEEL bolts do in our ALUMINUM warrior engines.

yes i must agree. use anti-sieze! ive snapped bolts and had to drill them out before because there was not any anti-sieze on them (not my fault). as for plugs, ive heard that the overpriced ones arent worth the money, but they definitely arent for me, since i have a v8 and im not spending upwards of 80 bucks to change plugs!

I use NGK Iridiums - in the YFZ they are worth it. They dont foul for **** and have a more crisp ignition.

I have a dodge ram hemi with 2 spark plugs per cylinder thats right 16 plugs. Im dreading the day I have to put new ones in. I m at about 70,000 miles and they say dont change em till 100,000 so im riding them till they dont spark anymore!!

Yeah my little 4 cylinder mazda pickup has 2 plugs per cylinder, which I thought was kinda funny for a truck like mine. I use champions just because thats what my dad always uses in his dodge ram. They say only to use ford plugs in my truck, but the champions seem to work good. later.
