Best Platinum On Center Electrode Spark Plug

Autolite Iridium XP Automotive Replacement Spark Plugs, XP5701 (4 Pack)

One-piece, fired-in suppressor seal blends three glass types for a gas-tight seal that helps reduce radio frequency and engine interference, regulate spark plug energy, and protect against compression pressures for long life.
Double platinum point pad on center and ground electrode offer excellent durability and consistent voltage demands to help reduce wear on ignition system.
Pure copper core results in cooler electrode temperature for maximized durability and fouling resistance.
Some ACDelco GM Original Equipment parts may have formerly appeared as ACDelco Professional.

Full platinum tip ensures virtually no gap erosion for long plug life.
Yttrium enhanced, high nickel alloy side electrode maintains precise gap to increase plug life.
Necked-down center electrode fires quicker and cleaner, with less voltage for easier starts, quicker acceleration, and improved fuel economy.
Platinum alloy pad on ground electrode provides extended durability and service life and platinum-to-platinum firing.
Nickel-plated steel shell for long-life corrosion resistance.
