Where is the engine air filter on the 2010 Lexus 450 h and how do I change it

The oil filter on a Lexus GX460 is a cartridge type filter located at the bottom front of the engine. It is difficult to see without removing the front engine undercover, which is basically a steel plate shield held to the vehicle by 4 bolts. Once the shield is removed, the oil filter housing is visible right behind and just above the stabilizer bar. The housing is positioned sideways and a large pair of channel locks can be used to unscrew the black housing cap. Make sure you have a drip pan ready because a fair amount of oil will drain once the cap is removed. After the cap is removed, it's a simple matter of removing the cartridge filter with your fingers and popping in the new one. A new rubber o-ring should be included with the replacement filter.

this vehicle may be due for a service.

slow starting in colder weather can be due to many issues. such as dirty or wet ignition sytem or low battery charge.
if you live in colder climate you may need to change your oil to a thinner one for cold tempretures.

also check that exaust pipe is not blocked, air filter is clean and fuel filter is not blocked.


I hope this was useful.

Check for rust and check the pressure in the engine - if when you remove the oil fill cap the gases are bursting out then the engine is worn out. Check the transmission's oil  and ask him if the filter has been changed - without that the life of the gearbox has been reduced.

filters must be free flowing to remove dirt and carbon the better the filter the better the engine will be kept clean

Those are the only 2 bolts

I just changed the cabin filter of my ES300. I found the instructions on the manual, under airconditioning and audio. It's pretty easy to do. I bought the filter from Kragen's for $21.95.

Jim , you can change both the air and cabin air filters. There are a series off pop pins covering the air intake. If you depress the center button with a BIC pen tip and then lift at the side they will pop up. They are a plastic spring load so be gentle.
Underneath you will find the intake housing and filter. Cabin air filter should be behind the glove box area I
believe .
FYI , Lexus has a patented high volume oil filter. If you change your own , stcik with genuine for longer life, unless you are certain the aftermarket matches

The engine air filter in a 2002 lexus ES300 is located in a black box behind the battery. It should have a thick air hose connecting to it which is the air intake. Open the two 10 millimeter bolts holding it together and open it and replace the filter.
