FUNCTION OF RC12YC SPARK PLUG -- The spark plug adopts copper core electrode. The copper core central electrode can accurately control the thermal range of the spark plug, optimize the performance of the spark plug and prolong the service life of the spark plug. Spark plugs offer reliable performance and durability, superior corrosion resistance and longer service life. Please rest assured to buy!.

0.4 mm iridium center electrode: world's smallest diameter that maximizes firing potential.
U-groove and taper cut ground electrode: provides faster spark flame growth and lessens heat quenching.
DENSO patented 360 degree laser welding process: ensuring exceptional quality bond and structural strength with the iridium center electrode.

FOR OPTIMAL PERFORMANCE: Automotive spark plug that fits a variety of domestic applications, designed to increase power, reduce fuel consumption, and improve hydrocarbon emissions.
PATENTED TECHNOLOGY: DiamondFIRE ground electrode is secured to the shell with 3 legs that help facilitate excellent heat transfer and increase turbulence in the cylinder.
INCREASED DURABILITY: Designed with colder heat ranges to enable performance modifications, and contains Yttrium-enhanced alloy for up to 8% reduction in side wire temperature for less pre-ignition.
WHAT'S INCLUDED: One (1) E3.62 spark plug. Features 14mm thread diameter.
0.708-inch thread reach plug with taper seat.
WARRANTY: Often used for domestics. Unique ground electrode and full-size center electrode provides optimal performance guaranteed for five years or 100,000 miles.

Solid state suppressor, with two-piece glass and brass seal, can help reduce radio frequency interference, regulates spark energy for long electrode life, and helps protect against high combustion pressures.
Pure copper core provides great heat transfer and helps maximize plug durability.
Platinum on center electrode enables superior spark characteristics and can reduce voltage requirements of the ignition system.
Ribless insulator helps optimize plug to boot seal.
