I own one Mercury, the Villager mini-van, but it's the wife's. :D
lol.. my finacee owns a 01 saturn l200. its going bye bye sometime this week.. that car sucks! its still a gm! am lookin to trade a o1 saturn for a 04 cavalier.. wait n see
 
ac delco for gm
bosh for german cars, autolite for chysler , motorcraft for furd, ngk for jap/asian. stick with what was designed for your applcation.

i got my 440 back from the machine shop with champs in it. with the jetting tuned to a tan color, the car ran like ****. the only way to get it to run strong was to jet it until the plugs were black and wet. bought some autolites and without changing anything, they were a little bit sooty but dry. after re-jetting, i saw more power and a good colored plug.
 
Champions in any form suck donkey hootus..

Hold a Champion up to an AC and look at the quality difference, pathetic...
 
One thing about plugs is that they tend to be fragile pieces. First time I had some "out of the box bad" Champions or somesuch, I vowed not to buy cheap plugs again. I dropped an AC Delco maybe 3 feet, hit just right,, and it broke where the porcelain meets the metal.

Then installing plugs with my new headers, used a deep well socket on a plug that can't be reached straight, and the plug cracked. Heard it, no idea what it was, finished installing, pulled the plug later for some reason, noticed the porcelain was cracked.

Moral of the story is, as fragile as plugs are, and the way things are shipped/handled nowadays, one or two bad experiences with plugs can't always be blamed on manufacturer. Multiple bad experiences at the same time or at different times maybe, but one or two bad "out of the box" plugs might be better blamed on bad handling. Certainly not saying cheap plugs aren't cheap plugs, just that certain things are out of our control as consumers.
 
want a multiple experience? champs in my dads 75 chevy half ton would always foul in a week or so. it would never start in the winter if it was below -25c even when plugged in. i put autolites in it and it never fouled again. would always start in the winter at temps below -30c without being plugged in. champs are just plain garbage.

Actually the ONLY bad plug I ever had out of the box, was an AC.. had a hairline crack that would cause misfire.. And not from the install..

But anyway, my statement wasn't a "one or two" time thing...

I install over a thousand a year probably, in groups of 16... Just look at a Champion, it's like 1970's tech, poor materials, etc... cheap or not, it's a poor product.. living off their name...
 
Here are 3 out of 4 NGK's from a low mileage engine. Hard to tell from the photo, but the lines you see from the metal extending out onto the porcelain is apparently where the fingers crimping the metal to the porcelain during production didn't meet. Those tracks/rust are combustion byproducts/results that have leaked through the plug body from the combustion chamber.

If the link doesn't work, I'll change the picture location.

Only reason the last plug diodn't do that was because it had been replaced by the dealer already. Those plugs have less than 30K on a stock, production, low hp, economy car motor. Apparently, paying more doesn't necesarily equate to a better plug. Didn't have the car long enough to know if the next set of NGK's did the same thing.

honestly, the only price I know of is, the platinums are huge coin... all the fourstrokes run em, and we get like $28 a plug.. had triple 250 outboards on a Fountain, the plug bill was like $550...

Other than that, I couldn't tell ya the dif in price on any standard plug. i figured they where comparable, AC to Champion to NGK, all within a buck or so of each...

but, I'm not even considering price.. Champions are just made like cr@p..

My last shop use to run NGK's alot with good success.. we'd buy the shoppacks of 25... I still say the quality of the plug is a tad less than an AC, but a decent plug...

id better change the spark plugs on the saturn too.. she hasnt been running good and misses a lil bit.. only has 65 k miles and its a ngk
 
Yep, definitely watched the mileage and performance decrease as they got worse.

One reason I *always* calculate mileage. Some engines are pretty good at masking problems, or are so weak you can't tell a performance difference. But they can't hide the mileage difference. :)

i run ngk's on my dirt bike, they work excellent, never ever foul even for a 2 stroke. i have bosch's in my truck but it needs a tune up, where did you guys get your set of ngk's? napa?
 
i got ngk from napa for saturn.. saturn doesnt run too good now.has misses. and i buy ngks for 4 wheeler dirtbikes. etc at napa too.. but ac delco is in my truck now.. runs better than ngks. and oem spark plugs is goin in saturn soon.. but on second thought its gonna be traded in very shortly,.. so will keep it like that.
 
well my history sounds like alot of all yous out there. champions SUCK, so do bosch, they all start terrible and foul quick, and dont fire worth a shiot, i bought a new set of champions just 2 weeks ago and my mildly built 327 would not fire on all 8 until it got to bout 160 deg, then when on all 8 it would miss and not run past 5000rpm, i needed plugs fast so i just ran to wally world and bought some autolite coppers #26 and it about blew my mind lol, i started my truck up and it idled good, hit the road and it ran to bout 7200 rpm with no misses and shifted and kept layin down the power, i left it sit a week and walked out and didnt even pump the pedal and it fired right up. i never thought that wally could sell something that i would put on my motor from time and time again but i think im sold on these plugs.
 
I've got AutoLite's in my 305. I have been running the same set for about 2 years now and I have absolutely no complaints.

The Lawn Equipment shop I work for exclusively uses Champion plugs. All small engines use Champion plugs and come from the factory that way.

My Kawasaki ATV 250cc came originally with a NGK and it's maybe 4 years old and has had some hard use. No problems with them either.
