Product Information

Product Details
Part No. 7422
Warranty Details (5 YR REPLACEMENT IF DEFECTIVE)
BOSCH Double Platinum Spark Plugs are engineered to deliver both performance and long life, representing the best of OE spark plug technology. BOSCH utilizes a platinum firing pin on the center electrode and platinum inlay in the ground electrode. This design reduces gap erosion, increases durability and performance life while meeting Original Equipment specifications for double platinum spark plugs.

Product Features:
  • Platinum on the center electrode firing pin and laser welded platinum inlay ground electrode provide 3 times longer life than conventional copper spark plugs.
  • OE Fine Wire design requires up to 24% less voltage to ignite
  • 360 degree continuous laser welding increases durability for increased life
  • Copper core provides broader heat range to resist pre-ignition and fouling
  • Pre-gapped and nickel plated threads allow for quick installation without adjusting the gap or applying anti-seize
  • Customer satisfaction guarantee (visit www.boschautoparts.com/sparkplugs for details)
