you dont need -8an. -6an in plenty. but if you must use the -8an to look cool then i would just go with one of these. [http://www.summitracing.com/parts/SUM-230105/](http://www.summitracing.com/parts/SUM-230105/) ---

micron is the filtering ability. not realy so much flow. anything you choose -8 will be more then enough for 500whp since thats realy not alot of power. I personaly run this filter and im making well over 500whp. [http://www.summitracing.com/parts/TFS-23001/](http://www.summitracing.com/parts/TFS-23001/) ---

I just run the factory efi canister’s, & Prior’s has ur basic inline filter’s, we’ve never had problem’s, just stay away from Res gas & you’ll be fine. ---
