Since were on the topic of airboxes, I think I'll share too. I've got a stock air box, and I"ve done similar mods. 1. I removed the old air scoop and replaced it with a larger 4inch intake tube
also i cut out 3 2ince holes and placed 3 two and a half foot long tubes in the air box. However I'm not sure if I should run the tube underneath the bumber and mount them so they face outwards. Will this cause any problems if it is raining out, I don't want any water getting in the intake. I've seen others with mods that run ram air scoops under the bumper, and FWI has anyone had any problems.
