The air filter compartment is in the back of your glove box. All you need to do is remove the main filter door, then the secondary door, then pull out the filter. The instructions are toward the back of the manual, complete with illustrations. It's really simple. I figure the dealer charges $15 for the part and $64 for labor.
You were told 15K? I thought it was every 5K, or I guess whenever it needs to be done. I'm taking my car for my 10K service tomorrow, and I was quoted $151 by 3 dealerships, but only one dealer told me that it could be $230 if I need the air filter replaced.
Thanks for the tip Cmasten. Is there a brand of filter I should look out for at Pep Boys? Do you know if an aftermarket air filter void the warranty? I wouldn't think so, but you never know w/Lexus.
Technically, that's the cabin air filter you're describing. The air filter is in the engine compartment. I just bought a pair from RockAuto.com. But, only 'cause I was restocking my garage with parts for my wife's es350 and my Tacoma - oil filters, cabin filters, air filters and surpentine belts. Otherwise, Pep Boys, or even Wallyworld filters will do.
