for low mileage use and when periodic maintenance is done once or twice a year, then an oem disposable air filter is just right. in my case, i do PMS minimum 3 times a year so i opted for a washable type air filter. iirc, oem air filter is P1.2k in casa, so thats P3.6k a year budget. my vehicle is more than 6 yrs old/185k+ kms now so i must have spent about P21.6k equiv for air filter alone if i'd stick to oem. the washable air filter was 4.2k back then and still in good shape and do its job until now. sulit na and the savings i had if you convert it to liters of fuel, ilang daang litro din yun. and so far, wala naman isyu sa engine cause by dirt or other particles na nakapasok sa engine internals probably thru air intake.
