Do plugs run hotter or colder?
What do the numbers on a Champion Spark Plug mean?
[15] Heat Range - The middle number indicates the heat range of the spark plug, the higher the number the hotter the heat range.
How do I know which spark plugs I need?
The different types of spark plugs can seem overwhelming at first, but the simple way to find out what kind of spark plug you need is by checking your owner's manual. The manual will specify the right plugs for your vehicle.
Which Champion plug is hotter?
Champion plugs are hotter the higher the number, colder the lower the number. Starting with part # RCJ7Y (heat range 7), a colder plug would be # RCJ6Y (heat range 6), a hotter plug would be # RCJ8Y (heat range 8). Once you have decided on a number, test to see if it exists by typing it into the search box.
Do I need a hotter or colder spark plug?
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 are the 3 types of spark plug?
Nowadays there are different kinds of spark plugs available in the markets to choose from i.e. copper, platinum and Iridium spark plugs. The copper spark plug is the most commonly used spark plug as it is the cheapest among the three.

What happens if I use 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.
What number spark 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).
What burns hotter BR8 or BR9 spark plug?
BR8 is warmer than a BR9.
What happens if spark plug is too cold?
If the selected spark plug heat range is too cold, the spark plug may begin to foul when the engine speed is low or when operating in cold conditions with rich air-fuel mixtures.
What does 1 step colder spark plugs mean?
Why go “one step colder”? Running a “colder” heat range spark plug will reduce temperatures in the combustion chamber by wicking more heat into the cylinder head. This reduces feedback knock and fine knock learning when running gasoline tunes. Recommended on ALL 2.5 WRX/STI making over 280 whp.
How do I choose a hotter spark plug?
The higher the number, the hotter the plug. The lower the number, the colder the plug. Starting with part # 24 (heat range 4), if you want a colder plug you would use part # 23 (heat range 3), for a hotter plug you would use part # 25 (heat range 5).
What is a resistor type spark plug?
Resistor type spark plugs reduce the amount of radio frequency interference (RFI) that can cause ignition misfires and static on the radio. [V] Shell Design - This refers to the thread size and reach of the spark plug. [15] Heat Range - The middle number indicates the heat range of the spark plug, the higher the number the hotter the heat range.
Do plugs run hotter or colder?
Please note, within a given plug family the plugs run hotter as the number gets higher. Generally, the Racing and Industrial plug families run colder than the automotive plug family even though they have higher numbers.
