What does the P stand for on NGK plugs?
The “P” indicates a projected tip spark plug design (1.5 mm projection) that moves the spark deeper into the combustion chamber. The letter “S” in this location indicates it is a standard (non-projected tip) type, while the letter “X” indicates a 2.5 mm projected tip.
Is there too big a gap on a Polaris spark plug?
Its a ZR 440. polaris is .028 so yes you have too big of a gap. .030″ is usually a good gap. You typically dont want a gap over .035″ because the wider the gap that spark has to jump is, the weaker the spark is and the more likely you are to foul a plug.
Why do spark plugs need to be gapped?
Since the gap size has a direct effect on the voltage necessary to jump the gap and ionize (light) the air-fuel mixture, careful attention is required. While plugs are pre-gapped from the factory, the gap may need to be adjusted for the vehicle that the spark plug is intended for.
What kind of spark plugs do snowmobiles use?
They come pre-gapped close enough. Most sleds use the BR9ES. The flat side of the screw driver that came in the kit for my ZRT is the same thickness as the gap is supposed to be, I don’t know if Polaris is the same tho, and you should always check the gap before you use them, you will find the odd one that is way off.
Where is the spark plug gap on a champion?
For Champion spark plugs it is a little less logical and is as listed below: Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode.

What should the gap be on a spark plug?
Proper electrode gap is .24”-.28” (0.6-0.7 mm).” All I have is standard gap, and I’m thinking manual has a typo and should read .024”-.028” Cause a ¼” seams like a rather large gap lol? So does anyone know proper gap. I could try and convert the mm but thought it may be wrong as well.
What is the part numbering for brisk spark plugs?
Part numbering for Brisk, NGK and Denso spark plugs is reasonably logical with the trailing digits transposing directly into size in mm. For Champion spark plugs it is a little less logical and is as listed below:
