回複：我前兩天問過另一個問題，２００９Camry, 兩萬碼了，該換Air filter 了，

I believe Toyota sells for $25.  You can find third party one for $10-15.  Quality should be pretty much the same.  Change by your self.  It's super easy.  Just take off hindge screw and push both ends of the glove box to take it off.  You can always search YouTube for instruction but pay attention to the year of Camry since it's a little different from year to year.
