just put in my JWT pop-charger...i heard that i have to oil it...how do i do that...and how often...also with this new loud mod on my car...will there be any change in fuel milage...thanx

 

Get a K&N brand "recharger kit" and follow those directions...

You should get the same mileage. You will be on the gas harder to hear the cool noise, so that will hurt it some.

 

The filter actually comes preoiled (red oil). You can use it as it, but when you want to clean it, get the K&N cleaning kit (cleaner and oil). K&N recommends cleaning every 50k, but I clean mine about every 10k.
