What are peoples recommendations of the best panel filter for my 04' WRX Wagon that is soon to be tuned slightly? I'm not going induction kit route as at the very mild mods i'm going for, it's not worth it.

I've been looking at the K&N ones as that's what i've always had on other makes of cars. Seems like it makes sense to stick with them this time then.

one of the jap mags did a RR shoot out on a blob STI only changing the filter.

pretty sure do luck came out as giving the most power under those circumstances
