Product Review
OE Copper core spark plug provides broader heat range to resist pre-ignition and fouling. The nickel-plated rolled threads is used for complete anti-seize and corrosion protection, and the angled, ribbed insulator design prevents misfire due to flash-over.
- Heavy-duty yttrium enhanced nickel-copper center electrode ensures superior reliability and durability for up to 50% longer performance life vs. standard copper plugs
- Copper core provides broader heat range to resist pre-ignition and deposit build-up
- Nickel-plated rolled threads provide superior resistance to corrosion and do not require anti-seize - saving time
- Angled, ribbed insulator design prevents misfire due to flash-over
- Metal glass fused resistor maximizes interference suppression
- Compatible with select vehicles (Note: engine affects fitment - verify specific fitment details with amazon confirmed fit fit checker above): BMW: 1988-91 M3, 1988 M5, 1987-88 M6
