Ut400 spark plug upgrade

[Coleman400]

Hey all. I need to change my plug in my ut400 and I remember seeing people in here saying to get a certain one that was better than what it came with. What was it?

Also I need to do an oil change. Are the tractor supply oil change kits ok to use?

 

Any help here is appreciated!

You might have better luck in the "coleman" forum.

Yes the TSC oil change kit should be ok. Make sure the oil is ok for a wet clutch, there are UTV/ATV/Motorcycle specific oils or Shell Rotella that are wet clutch compatable.

As far as plugs look up the iridium cross reference. Some people have gone up a heat range to reduce fouling, but you run the risk of knocking.

Just Dont use a full synthetic auto oil,, will destroy your wet clutch .. I use Castrol Actevo  in all of mine.  Buying expensive plug is waste.. You wont drive 100,000  miles and thats the only advantage to exotics. Copper plugs have better spark...
