Bosch Super Plus spark plug has a premium copper core plus yttrium enhanced center electrode providing extended performance life over conventional copper core spark plugs.
- 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: 1986-88 325,1984-87 325e,1986-87 325es,1987-91 325i,1987-91 325is,1988-91 325iX,1989-90 525i,1982-88 528e
