What is the purpose of the resistor in this spark plug?

The resistor inside this spark plug helps to suppress radio frequency interference. This can prevent electrical noise from affecting your vehicle's electronic control unit (ECU) or other sensitive onboard electronics.

Why is the 12mm thread size important?

The 12mm thread size specifies the diameter and pitch of the threads on the spark plug. It's crucial for ensuring the plug screws correctly into the cylinder head of your engine.

What does it mean that this is a 2-pack?

A 2-pack means you receive two spark plugs in this package. This is convenient for engines that require two spark plugs, or to have a spare on hand for future replacement.
