This is what I did... I bought a universal cone airfilter, and universal breather filter for the crank case. I removed the factory airbox completely. I kept the factory intake tube that went to the throttle body, and airbox. I used a can from corn, yes I said can from corn. I cut the top and bottom of the can off with a canopener, and rinsed the can out thoroughly. After the can dried, I installed it into the intake tube, and put the cone filter on it. I've gained more MPG and slight HP. For the total of $45, and 30 minutes of work, it was worth it. I call it the poor mans cold air intake, and it works just fine. I've noticed throttle noise when I step on it, and it sounds good. Figured I would just let you know what I did, to give out a helping hand.
