NGK BPR5ES-13 Spark Plug - BPR5ES-13

The 'BPR' indicates a resistor type spark plug with a projected electrode. '5' is the heat rating, 'E' denotes the thread size (14mm), 'S' means a standard ground electrode, and '13' typically refers to the pre-set gap or specific terminal type, although for this plug it indicates a 3mm spark projection.

Replacement intervals vary depending on the engine and driving conditions. Consult your vehicle's owner's manual for the manufacturer's recommended service interval. A general guideline for copper core plugs is typically between 10,000 to 20,000 miles.

No, this NGK BPR5ES-13 spark plug is designed specifically for petrol (gasoline) engines. Diesel engines use different ignition methods and do not use spark plugs.

The primary difference is the spark projection or gap. The '-13' typically indicates a 3mm spark projection, while the '-11' often refers to a smaller gap or projection. Always use the specific part number recommended by your engine manufacturer.

The '-13' in the part number for this specific plug relates to its construction and spark projection (3mm). While often considered factory-set, it is always recommended to check the gap against your engine's specifications before installation, using a feeler gauge.

You will need a spark plug socket wrench of the appropriate size (usually 13/16 inch or 20.8mm hex), a ratchet, and potentially a torque wrench to ensure proper tightening.

Check that the spark plug is correctly installed and tightened. Ensure the spark plug wire is securely connected. Inspect the spark plug for signs of wear or fouling and replace if necessary.

Verify the spark plug is the correct type for your engine. Ensure it is properly gapped (though this model has a fixed gap) and seated. Check for other potential ignition system issues.

Worn or fouled spark plugs can reduce efficiency. Ensure the NGK BPR5ES-13 is within its service life and that the engine is tuned correctly. Check for proper air-fuel mixture.
