As Niky said, you have to clean, re oil it properly by using the K&N Recharger Kit -if not well sayang lang as you will not get the full benefit of it.

Really depends on the owner whether to replace the OEM on not. For example if the OEM filter costs about 2K+ like the current Montero then replacing it with K&N washable filter is an excellent option for a lifetime use. K&N Filter is good for 50,000 miles in the USA before cleaning / recharging.

Honestly, in my 3.2 Monty it goes from 7.6-7.8 to 8.4-8.6 kms/L on city (tipid mode). the plus factor is the added HP when you need it .

Tidus, i'm selling K&N Air Filter for Montero/Strada (only) and Recharger Kit for only Php750. Good for 3-4 cleaning.


K&N Filter is the World's Best Filter.
