I have an Injen SRI and I'm just wondering how often I need to change the air filter and where can I get them???
If I'm not mistaken, you can just clean it and put it back on. I don't know if yours has to be oiled or not...but just clean and re-oil every couple oil changes or so.
I have 5 filters. I replace them everytime I do an oil change. So I have 4 right now that need to be slightly cleaned and reused. Yay for backups.
i clean mine after every 6k miles but put a new one on at every 12k. so clean change clean change repeat
