Lexus Air Filter FAQ
Lexus Air Filter FAQ
Typically in a black box next to the engine, under the hood. Keeps the air entering the engine clean.
Service Interval: 12k-30k
Air filters may become restricted with dust and still look relatively clean. Simply knocking the dust out of it does not help this matter.
Why do we replace/service:
Keeps your engine running as efficiently as possible, the better your engine can take air in, the more efficient it can be.
What happens if we don’t service:
Idle may become rough and random, fuel economy may decrease significantly. The Lexus engine may not start or may need excessive cranking to get it started, eventually it can cause problems with the proper air to fuel ratio and cause other failures in the fuel system.
General Recommendations:
Change your air filter every fourth or fifth oil change, perhaps more often if you live in a desert/dusty environment or a large city. Never run without an air filter, with an air filter with a hole in it, or one that does not seal properly – even small dust particles can cause added wear inside an engine and also contaminate the oil. Some manufacturers, such as K&N, offer air filters that never require replacement, only cleaning periodically.
