I change mine bout every 300-500. Don't know why. I just do lol

 

I have 1500 miles changing them in the spring

 

Well, since I only have 1,800 miles on the machine, and still on the original plug, I am forced into the "Between 1000 and 2000" category.


All the best, James

 

Seemed a little silly to make it too granular.
Sorry if you felt forced.

 

No, no, no! I wasn't being snippy. It's hard to be ironic through a forum post, my bad, and my apologies.

What I was trying to say is I'll run this plug as far as it will go. So far, that's only 1800 miles...but it's performing great right now.


All the best, James

 

Before the turbo, I still had the original plugs in it at 1200 miles and when I did the rebuild ( CP pistons and P&W crank, not wear issues) they looked new. Now I change them every spring but they looked great each time.

 

Just over 5000,had them out a couple of time's looked ok.

At 3000 miles they looked ok, but wile I had them out I went ahead and changed them.

 

I always changed mine during the anual oil, filter, diff lube changes. Just for safe measures but probably not al all necessary.

 

If it's running clean no reason why they shouldn't last.

Bump!

 

I installed a set of NGK Iridiums in my pickup over 100K ago; still going strong. I installed a set of Iridiums in my RZR as soon as I brought it home; they've made it over 2K miles with no problems. I'm expecting them to last a whole lot longer...........

Cheers

 

I put 100k on original Autolites in my truck before changing. Yea the gap was a little wide (65 thousanths) but they still worked. I pulled my original RZR plug (NGK Iridium) at 1200 and it looked brand new. Changed it anyway but using the old one as a spare.
If your EFI is working properly, plugs should last a very long time!

 

Mine has 2200 miles on it. Changed to NGK iridium since I had the bed off doing some other work.

is this on a 900? If so whats the part number? thx

 

5896 miles, 290 hours on plugs, 5500 on belt

 

I'm close to the same miles on the OE plugs and belt.
I have no plans to change the plugs. Almost all cars go 100k on plugs now days so I figure if I'm not running rich (over fueling) and not burning oil the plugs should out last the machine. I will look at them every few years just make sure. So for now I voted 5000 on more

 

Nice to see some other higher mile RZRs out there! 3650 miles and counting...

 

2700 mi. on original plugs here. Runs great.

 

Almost 7000 miles

 

Rebuilt primary clutch and replaced secondary, both worn out. Belt lasted longer than clutch. Mostly high speed desert travel. Lots of tires, no bearings, lots of grease, oh and a broken sway bar.

 

Are they platinum? I haven't looked at mine so I didn't vote . Back before unleaded fuel they would get dirty now days if your eingine is in good shape I would think they would be the least of your worry's? Has anyone changed them because they were bad?

 

Ive got 7200km (4500ish miles) on my stock ones...im gonna change em soon though just cause the beds commin off for unrelated reasons...

 

I'm pulling mine after ~1100 miles to install a Weller Racing cam chain tensioner. Since its running well, I'll check the gap, anti-seize them and reinstall.

 

They were fine. Now at 1500 miles. Its fuel injected with electronic ignition and running unleaded fuel. If the NGK's don't last a long time I'll be surprised. Two new MR7F's as spares, though.

 

5300 miles on my '14 xp1k, have a set of NGK Iridums on the bench ready to go in next time I have the cover off.... Maybe

 

Just changed mine at 2900. The only reason I changed them was because I had a set in an oil change kit and I had the bed off to replace the throttle cable. Much, much better throttle response and acceleration, but like I said, I done the throttle cable at the same time.

Off topic, but check Your throttle cable adjustment. Mine had a lot of play and it or the plugs made a BIG difference.

 

In a perfect world, standard copper plugs will last about 30k miles before electrode wear and misfires become an issue. Especially so on boosted applications. Platinums and Iridiums can push the envelope to 100k+. I still don't like to push those beyond 60k anyway.

My RZR on the original plugs made it to about 750 miles until they got slight fouling from lots of cold starts and not allowing it to run. Caused cold running hesitation and misfires.

On my drag car, I would use standard coppers and change them out at least every other event.

Spark Plugs are consumables. Treat them as such.

Every 50,000 or so they are good in a car for 100,000

 

4400+ and counting on oem plugs.
