I would in a New York minute if I could pick up a spare intake tube and airbox. Otherwise, I'd like the Stage 2v5...

Understood. I'll have to monitor my gas mileage over a couple more tanks to see just how significant of a change there has been. I have been getting on the throttle a lot more of late - I just love taking it into the 3,000+ rpm range! The sound gets higher pitched like a Porsche and the car really takes off...
