NGK Spark Plug - BKR6EIX - 6418

While these plugs are often set near the correct gap, you should always check the gap against your engine's requirements and adjust if necessary.

NGK utilizes trivalent metal plating which serves as an anti-seize agent. The use of additional anti-seize compounds is generally discouraged as it can lead to over-tightening.

Replacement intervals vary by engine and driving conditions. Consult your vehicle's owner manual for the recommended service interval for iridium-tipped plugs.

No. Compatibility is strictly determined by your engine's design. You must check the specific part number requirements in your vehicle manual or an NGK fitment guide.

Iridium has a much higher melting point and greater strength than nickel or copper, allowing for a much smaller center electrode, which requires less voltage to fire.

Verify that the spark plug wire or ignition coil is fully seated on the terminal and check that the spark gap is within the vehicle manufacturer's specification.

Stop immediately to avoid cross-threading. Remove the plug, inspect the threads for debris, and attempt to hand-thread the plug again to ensure correct alignment.
