Keep your snowmobile in top performing condition by changing out your spark plugs on a regular basis. For moderate snowmobile use, one set of spark plugs per season is sufficient. If you’re riding hard and often, be prepared to change out your spark plugs more frequently.
Does indexing spark plugs help?
Indexing spark plugs can prevent pop-up piston dome contact from closing up the plug gaps and May also enhance flame propagation in older inefficient combustion chambers. Spark plug indexing sometimes is necessary to avoid side-electrode contact with high-dome pistons.
How do you check snowmobile spark plugs?

What happens if you fuel with ETEC plugs?
Although the ETEC fueling is precise and these plugs GENERALLY do not foul, what does happen is the ETEC runs much hotter than a carbureted sled and the additional chamber temps can compromise the plug gap and additionally cause insulator wear. This can result in requiring additional voltage loads to achieve proper firing.
