What is the difference between a BR9ES and an BR8ES?
The heat range of a spark plug is indicated by the number in the plug’s identification sequence. On NGK spark plugs, the lower the number the hotter the plug (higher numbers are colder). Thus, your NGK BR9ES is colder than a BR8ES.
Whats the difference between BR9ES and BPR9ES?
tHE BPR9ES is the plug for polaris sleds. Thats the P designation. The BR9ES will run fine and only costs 2 bucks. The BR9ECS is made special for Doo.
What does the P mean on NGK Spark Plugs?
projected insulator
C = hex size 5/8″ K = hex size 5/8 with projected tip (ISO) M = compact type P = projected insulator type R = resistor SD = surface discharge for rotary engines U = semi-surface discharge Z = inductive suppressor.

Which NGK plug is hotter?
NGK indicates the heat range in the middle of the plug number. For example, BCPR6ES-11 has a heat range of 6. (The number after the “-“ is the gap.) Starting with part # BKR6E-11 (heat range 6), a colder plug would # BKR7E-11 (heat range 7), a hotter plug would be # BKR5E-11 (heat range 5).

Do I need a hotter or colder spark plug?
When making spark plug heat range changes, it is better to err on the side of too cold a plug. Running too cold a plug can only cause it to foul out, whereas running too hot a plug can cause severe engine damage.
Do Iridium plugs burn hotter?
What about iridium spark plugs? Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point.

Fits Snowmobiles: Artic Cat Bombardier, John Deere, Fuji, Scorpion & Yamaha.
What happens if you run a hotter spark plug?
These accumulated deposits can result in spark plug fouling, leading to misfire. If the tip temperature is higher than 1560°F, the spark plug will overheat which may cause the ceramic around the center electrode to blister and the electrodes to melt. This may lead to pre-ignition/detonation and expensive engine damage.
Will a hotter spark plug stop fouling?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation.
Which spark plug is the best for performance?
Iridium
Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.
Do colder spark plugs increase horsepower?
Do Colder Spark Plugs Make More Power? – YouTube
Should I GAP my iridium spark plugs?
Iridium Power Gapping Tips
In most cases your Iridium Power plugs do not need to be gapped. Even with small variations in the factory set gap the ultra-efficient firing power design will compensate for those small variations.
Is it worth buying expensive spark plugs?

Should I run a hotter or colder plug?
Is a colder spark plug better?
Cold spark plugs are good for high RPM engines and other situations where the engine operates at a high temperature. Because they transfer heat faster, cold spark plugs can get dirty and become fouled sooner because they don’t get hot enough to burn off carbon deposits.
When should you use a hotter spark plug?
1. Air/Fuel Mixture: Lean air/fuel ratios raise cylinder-head temperatures, requiring a colder plug. Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean might contribute to preignition or detonation.
What spark plug gives the most horsepower?
If you want spark plugs for better performance and buttery smooth idling, then Iridium plugs are the perfect choice. Prepare to pay up to three times (or more!) for Iridium vs Platinum, but they’ll usually last longer, deliver more horsepower and breathe new life into your car!
