Spark Plug Champion Rc21 Hidden Electrode

Description

Champion RC21 Spark Plug Hidden Electrode 

The Champion RC21 spark plug has a high thermal range, which allows it to function under adverse operating conditions of worn engines and with high oil consumption. Thanks to its thermal capacity, it helps to properly burn the excess oil combustion mixture in the cylinders, avoiding power loss due to premature deterioration of conventional spark plugs.

Due to its dimensional characteristics, the RC21 spark plug can replace the "N", "RN", "C" and "RC" series spark plugs, including the N21. It has resistance and its hexagon is 5/8, which allows its use in recently manufactured vehicles, from 1992 onwards (designed with an electronic ignition system). In addition to all models prior to this date. Applicable to Japanese, Korean, European and American vehicles.
