K&N drop-in air filter, WORTH IT?

[XTO]

^^Hehehe kaso Toyota Yaris yung car in question...

Kaya nga depende kung mura lang yung OEM paper filter, and you don't really need the added response then not worth it. Like the case of my Crosswind nasa Php500 lang OEM and less than Php200 ang replacement and i don't really need if ever meron man madagdag na gain kaya di ko na nilagyan ng K&N - baka lalo pa bumilis eh
