Setup, Compatibility & Care
Compatibility: Before purchasing, always verify that the NGK IFR6D10 spark plug (MPN 5344) is the specified replacement for your vehicle's make, model, and year. Consult your vehicle's owner's manual or a reliable parts catalog. Ensure the thread size (14mm), thread length (19mm), and spanner size (16mm) are correct for your engine.
Installation: Ensure the engine is cool before beginning. Use a 16mm spark plug socket and a torque wrench. Apply a small amount of anti-seize compound to the spark plug threads if recommended by the vehicle manufacturer. Tighten the spark plug to the manufacturer's specified torque. Over-tightening can damage the cylinder head or the spark plug itself.
Care: Spark plugs are maintenance items and are not typically 'cleaned' for reuse. When they reach the end of their service life, they should be replaced. Inspect old spark plugs for signs of wear, fouling, or damage, which can indicate other engine issues.
