Fire a precise, high-intensity spark with the DENSO Iridium Power Spark Plug (MPN 5344). This iridium plug is a direct-fit replacement for the listed applications — including the 2013-2015 Acura ILX [L4-1.5L], 2007-2013 BMW 328I [L6-3.0L], 2015-2023 Dodge Challenger [V8-6.2L], 2007-2015 Lexus RX350 [V6-3.5L] and 2021-2023 Ford F-150 [V6-3.5L]. See the Buyer's Guide tab for the full list of 142 applications and engines.
A spark plug delivers the ignition spark that lights the compressed air-fuel charge in each cylinder; worn or fouled plugs are a common cause of misfires, rough idle, hard starting and reduced fuel economy. If a failed plug is the cause, this DENSO unit replaces it.
Iridium center electrode: a 0.4mm iridium tip on a copper core, designed to concentrate the spark for reliable ignition.
Ground electrode design: tapercut, U-Groove ground electrode (nickel core, standard configuration, one ground electrode) intended to aid flame propagation.
Specs: 14.0mm thread diameter, 16mm hex, 26.5mm reach, flat seat, 1.1mm pre-gap and 5000-ohm resistance (heat range 20).
The quantity needed varies by engine (from 3 to 16) — check the Buyer's Guide tab for your application. Manufacturer part number 5344. Country of origin: United States.
