Platinum Multi-Ground Plug unique firing technology combines the advantages of surface air gap technology and 4 yttrium enhanced ground electrodes.  The 4 ground electrode design not only provides multiple radial spark paths but also the surface air gap design create optimal plug life.
- 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): AUDI: 2000-06 A6 Quattro, 2000 A8, 2000-06 A8 Quattro, 2003-05 Allroad Quattro, 2004-09 S4, 2008 S5
- Compatible with (continued): AUDI: 2001-03 S8; VOLKSWAGEN: 2004-06 Phaeton, 2004-06 Touareg
