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): BMW: 2011 1 Series M, 2008-10 135i, 2011-13 325i, 2007-10 335i, 2009-10 335i xDrive, 2011-13 335is
- Compatible with (continued): BMW: 2007-08 335xi, 2008-10 535i, 2009-10 535i xDrive, 2008 535xi, 2011-12 740i, 2011-12 740Li, 2008-10 X6, 2009-16 Z4
