Verify the required thread diameter, reach, seat style, heat range, resistor type, terminal configuration, and electrode gap before ordering. BPR5ES should be described as a replacement spark plug, not automatically as an engine upgrade.

Installation Guidance:

Turn off the engine and allow it to cool before removing the existing spark plug. Clean the area around the plug to prevent debris from entering the cylinder.

Check and adjust the electrode gap according to the engine manufacturer’s specifications. Begin installation by hand to avoid cross-threading, then tighten the plug to the torque specified in the engine service manual. Do not overtighten.
