Not sure what´s your goal, but the autolites 764 are the correct sparks for that engine and cost 1/4 of the ngk´s...

Yeah, explain what you think it will do or what your trying to fix.
Just don't put champions in it.

Thanks for responding. The reason I wanted to use NGK plugs is because I work at a automotive dealer and NGK is our main supplier. I can get them at cost , so cheap.

Thanks

Ngk iridiums are good plugs.   Iridiums are shown to give you more power vs even brand new std copper plugs.   Yes, there are dyno charts proving it for those that don't believe it.

Beyond that, I have used them in my sportbike for years with great results. I have a few mods done to it and despite fairly extensive efi tuning, I still had a rich lower rpm a/f ratio.   It would foul out the stock dual electrode ngk's after a few weeks, but the performance of the bike was so good that I tried iridiums as they are known to foul less. Long story short is that they did solve that issue, and that same set has about 20,000 miles on them with no issues. It starts better too vs the std plugs.

I recently took my car to the dealer for an oil change, you know the kind where they tell you you have to spend $9,000 on other service for your car. They told me it was time for plugs and wires for a mere $500. Last fall I traded my other car in with 236,000 miles and original plugs and wires. I passed.

close to 100k on the F-150 and I got all the original stuff in there too. Runs great and gets over 14mpg towing the boat with the ac on.

Some vehicles have iridiums from the factory.   I know our v8 4runner had them factory installed.

No, they are not cheap. Iirc, I got mine for the bike from napa for like$ 9 each. Good thing I only needed 2 of them.

Anyone running std copper plugs on a car for longer mileage should bare minimum check the gaps. Platinum hold better gaps than copper ones.

i talked to MSD about their buzz boz on a car and the iridium tips kept burning the electrodes, it may have been the platinums, but i was told you have to run the coppers with that type of voltage???

Almost any toy, and basically anything with a carb you are going to end up futzing with the plugs long before you burn down the electrode on a copper plug significantly. The platinums and iridiums certainly have thier place in modern cars where for all intents and purposes they should never need to be changed (although good luck getting them out if you leave them in there for a couple hundred thousand miles).

Running a dyno test comparing two sets of plugs is pretty damn difficult. The small difference in HP could be just as easily be from the indexing or gapping changes and not from the plug design.

If one seems to resist fouling more than another the same thing could likely be accomplished by going up a heat range in the same design plug.

If it runs good now spend the money on gas..

Thanks to all,

Well I decided to get them at a great price, $3.90 each. I will post back with results. To be honest the Autolites gave me no problems at all. Just like to see if there is a difference.

Post later,

Hudson

For 3.90 a piece I'd run iridium plugs just for kicks. Hopefully you'll go from 15 gph at WOT to 14!!!!

on the new Merc outboards, it is a must that the plugs are indexed, according to a certified outboard guy, you have to keep trying them until they are indexed correctly

Indexing is pointing the ground strap on the plug in the proper relationship to the combustion chamber/block.

I got ya. I've always refered to that as gaping. You learn something new every day.

The merc outboards are running ngk tr55-ix plugs if my memory is correct. Indmar is also running them

Eric,
Gaping is the distance between the ground strap and the electrode. Indexing is so the ground strap is lined up in a certain direction when the plug is torqued down. Since the treads on the plug and block are not oriented, this is a trial and error process. You mark the side of the plug where the ground strap is and then install it. It the mark (IE: ground strap) isn't in the correct spot on the block, then you try it in a different cylinder and try another plug in the one you just removed. If you're lucky, you won't go through 2 or 3x the plugs you actually need!!

Ohhhh. Never done that with the new mercs I've done plugs on. Always just tossed them in there.

With how clean the new outboards run there's no reason these people should be changing their plugs each season

dont qoute me, but it may not be the Merc engine, its one of the newer outboards that you have to do this on..I turn away outboards anymore unless its a pump change or a mechanical issue...i dont even want to get involved with them anymore, i see what this guy goes thru with them and he needs a case of beer at the end of the day....his shop is set up with a drive in tank for the boats, so he knows what he's doing and still has issues with outboards

Eric,
Its probably the Evinrude your thinking of, they have BRP's E-Tec motor's in them.
Same design as my new Skidoo E-Tec and yes, YOU HAVE TO INDEX the plugs on the E-Tec

I hate evenrude for buying bombardier (or the other way around bombardier buying e-rude) simply because of the twin rotax motors they put in sea-doo challengers!!

The gains were not small gains. They were around 6-8 hp just from iridium plugs alone on a v8. I don't recall if it was a ford chevy or a dodge motor I saw the results from in one online instance.   No other changes other than possible indexing change were done. I've got important stuff to do now, (as I always do since there never seems to be enough time in the day), but if I have a moment of 20, I'll post a link.

Also, speaking with a well known dyno operator for bikes, he told me flat out that iridiums make more power in every case vs the std non iridium bike plugs.   

Yes, you could go up a heat range to get better foul resistance, but you could also have other serious issues if you go up a heat range.

The only time I've seen a non Rotax engine in a Bombardier PWC or snow mobile is the very early Ski-Doos. They were running 4 cycle Kohler 7 hp's in them!! That takes me back a few years! Actually, those Kohlers were more reliable than the early 2 cycles!!

Wow Pete that is a while back. I remember the single lung Olympics. You had to be careful not to let your scarf get sucked into the carb.
That was the good old days when you rode for two hours then wrenched on it for the next hour.
At least you could work on it yourself with my new sled you have to have a computer to diagnose anything.

Paul,
So, you ran with the venturi up grade on the carb too!! How about the Wisco pistons? JLO, CCW and Hirth come to mind after the 4 cycles.
