stock air box
hey 02 svt lightning..i don't have one but thought it was worth mentioning that the air inlet at fender is significantly more generous on the 03 -04 models.i personally use bulk unifilter green obtainable at off road motorcycle shops for $15 a bag.i double them up(2 bags) trim and lightly oil them on one side only.i merely sandwich them between the clamshells of the air box and trim off the excess.they flow pretty well and filter really well without getting maf coated.if you do manage to obtain an 03-04 air box you might want to open up the inlet at you inner fender to match..good luck I hope this helps
