Champion REA8WYPB4 OE253 Spark Plug Iridium

The Champion REA8WYPB4 is part of the Champion Iridium range.Champion Iridium uses a fine-wire iridium centre electrode with a platinum patch on the ground electrode, so both firing surfaces resist erosion. Iridium's hardness and high melting point let the tip be made very thin, which concentrates the spark, lowers the voltage needed to fire and improves cold starting and idle stability. Supplied as the original-equipment replacement where Champion iridium is specified, and as a long-life upgrade over the equivalent Champion copper plug of the same heat range. Cross reference (approximate equivalents): NGK ILKAR7L11. Equivalents from the manufacturers’ cross-reference charts – check thread size, reach and seat type before fitting.
