Mitsubishi Double Iridium Spark Plug 1822A085 NDILFR5A-11

When your Mitsubishi shows unstable idle, weak acceleration, significantly higher fuel consumption, or cold-start difficulty, it typically indicates spark plug electrodes aging and reduced ignition energy. The plug properly ignites the mixture to ensure smooth power output and thorough combustion. Fits many Mitsubishi models after 2000; OEM numbers 1822A085 and NDILFR5A-11. Install with a torque wrench to standard torque, avoid over-tightening damaging threads or under-tightening causing leaks; also clean cylinder deposits.
