Product Details
✓Heavy-duty yttrium enhanced nickel-copper center electrode ensures exemplary reliability and durability for up to 50% longer performance life vs. standard copper plugs
✓Copper core offers a broader heat range, reducing the risk of pre-ignition and deposit build-up to help maintain OE-level performance and economy over time
✓Angled, ribbed insulator design keeps flash-over causing oil, grime, and debris out of the spark plug wire or coil on plug boot, ensuring electrical energy goes into the spark plug - not around it - preventing misfire
✓Metal glass fused resistor maximizes interference suppression, protecting sensitive onboard electrical components like engine management modules, sensors, sound systems, and other sensitive electronics from undesirable RF energy
✓Nickel-plated rolled threads provide maximum resistance to corrosion - ensuring the spark plugs remove easily from the cylinder head without galling - and do not require anti-seize during installation - saving time
