AIR CLEANER Always replace with recommended platinum-tipped spark plugs. If maintenance is required, see an INFINITI dealer for servicing. The filter element should not be cleaned and reused. Replace it according to the maintenance intervals. See the INFINITI Service and Maintenance Guide. When replacing the filter, wipe the inside of the air cleaner housing and the cover with a damp cloth. WARNING SDI0145D REPLACING SPARK PLUGS If replacement is required, see an INFINITI dealer for servicing. Platinum-tipped spark plugs It is not necessary to replace the A platinum-tipped k spark plugs as frequently as the conventional type spark plugs since they will last much longer. Follow the maintenance schedule in the INFINITI Service and Maintenance Guide, but do not reuse them by cleaning or regapping. Operating the engine with the air cleaner removed can cause you or others to be burned. The air cleaner not only cleans the air, it stops the flame if the engine backfires. If it is not there, and the engine backfires, you could be burned. Do not drive with the air cleaner removed, and be careful when working on the engine with the air cleaner removed. Never pour fuel into the throttle body or attempt to start the engine with the air cleaner removed. Doing so could result in serious injury. 8-20 Maintenance and do-it-yourself
