Good To Know

Q: Is it necessary to replace all coils and plugs at the same time? A: Replacing these components as a complete set ensures uniform ignition output across all engine cylinders and prevents future misfires. It is highly recommended to change them together to maintain engine balance.

Q: What is the recommended gap for these spark plugs? A: These spark plugs are typically pre-gapped, but always verify the gap setting against the vehicle service manual before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
