Binaliktad mo yung air filter? Your sucking all the dirt that was trapped by filter to your engine. Excellent way of destroying the engine... just change the air filter with a new one
Not the filter itself. Yung bilog na plastic na may fins.Ganito yung pagkakabit ng mekaniko:
Tinanggal ko muna yung plastic "fins".
Also, I noticed na hindi ganon kadumi yung air filter. I think masyado narerestrict yung hangin papasok sa loob ng makina.
