love it.
This filter fits a 2008 Lexus RX400h perfectly and gives the fresh, clean air. I recommend it.

Good quality filter. Fair price.
Size: (Pack of 1)
Fit right, easy to install, high quality filter. The oil change places make their money on these add-ons. We let them check it at oil change time but order online, get it the next day, and do our own replacement in minutes. Money saver IMO.
