Bosch Copper with Nickel spark plugs feature a heavy-duty yttrium-enhanced copper core center electrode for improved durability
- 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): MERCEDES-BENZ: 1990-93 300CE, 1993 300E, 1992-93 300SE, 1990-93 300SL, 1993 300TE, 1992-93 400E, 1992 400SE
