Lexus RX350 Spark Plug
The Lexus RX350 Spark Plug generates the perfect amount of electric flash to ignite the compressed air-fuel mixture to help the engine fire up and run smoothly. In all Lexus RX350 engines, high voltage from the ignition coil jumps the gap between the central and side electrodes of the Spark Plug, causing the mini lightning bolt of ignition, which is responsible for the combustion of the air and therefore the downward movement of the piston. At idle, the Spark Plug fires hundreds of times per minute, and at highway pace, it can exceed a thousand firings, so Lexus uses durable materials and gap settings to help the Spark Plug survive thousands of miles without misfire. Over the years, the RX350 has been produced with both standard single-ground designs as well as updated designs with multiple ground electrodes or surface-discharge layouts, both types designed to increase ignition reliability and extend service life. Whichever format it is fitted, the Spark Plug has to maintain that proper heat range and gap to prevent Spark Plug fouling or pre-ignition to deliver the quiet strength to which every Lexus RX350 is known on the road.

Lexus RX350 Spark Plug Parts Questions & Experts Answers
- Q: How to replace spark plugs on Lexus RX350?A:Don't adjust the gap on iridium spark plugs as it may damage the plating. Use a spark plug socket with a rubber grommet for replacement. Use manufacturer-specified iridium-tipped plugs and avoid any with cracked insulators. Remove engine cover(s) and disconnect any interfering parts. Clean any dirt with compressed air. Remove the ignition coil assembly from each plug. Apply anti-seize compound to the plug threads and use a rubber hose for alignment. Tighten the plug to the specified torque and attach the ignition coil assembly.
