Instructions for Replacing Spark Plugs

Model: Lexus IS MK 2 - Years 2005-2013
Part: Spark plugs

To carry out this maintenance, operate with the engine cold; remove the plastic cover on the engine, detach the intake duct, unscrew the fixing screws of the ignition coils, disconnect the connector, and extract the rubber cap. Before removing the spark plugs, blow into their respective seats to eliminate any dirt that could enter the cylinders. At this point, remove the spark plugs and install the new ones without exceeding the tightening torque. Finally, reverse the process to reassemble the caps, the intake duct, and the cover.
