The bigger the tune the more fuel you are pushing through the filter. Also the more fuel that is needed for the higher HP tunes the more the filter clogging is exposed.
I change mine every 15k or if ity becomes clogged before that. I also run a FilterMag on my fuel filter to trap any rust from a station I may pick up. I feel its cheap insurance.
One good reason to use a FilterMag on your fuel filter. It won't help the water but it will trap the rust and metals in your fuel filter and keep it from getting into the injectors.
Changing filters like that you will be able to get more than 25k based on UOA. Many will change the full flow at 12-15k and the BP at 25 sample and results will say go longer. You will be fine and easily get 25K.
I think I can still get these for 360.00 a set shipped. They are OEM GM I can go pick them up from him and ship them to you.
If anybody is needing some let me know and I will check my source.
