KnN filter number for 273 commando 4bbl

Funny you should mention it, I did remove the throttle plates! It's fun to be in WOT all the time! Thanks for the info though, I'll most likely still go with the KnN just because I have had good luck with them in the past, more in terms of longevity than anything else. Its become part of the "oil change ritual" to pull the KnN filter in whatever I'm driving and clean/re-oil it. So, not too worried about gaining 1 HP as much as its nice to not have to buy a new filter every year. Becides, gotta keep that 7 1/4 alive for atleast another summer! lol thanks guys!
