8 pc NGK Iridium IX 6510 Spark Plugs

$92.99

NGK Iridium IX 6510 spark plugs, a set of eight with iridium center electrodes for classic truck V8 builds. They come pre-gapped. Adjust the gap to your application.

  • Iridium center electrode - a finer tip concentrates the spark and lights the charge more completely than a standard plug.
  • Eight in the box - a full V8 set in one order rather than counting singles into a cart.
  • 40;000 to 50;000 miles - a published service life instead of guessing at the next tune up.
  • Cleaner off idle - complete ignition in the chamber is what you feel the moment you touch the throttle.
  • New; not reboxed - the condition is published as new.

Install Level: Easy
