I did the "poor man's ram air" mod but I blocked off the stock "hot air" intake hole to ensure cooler air. I notice it a little on the top end, but "de-screening" the stock air filter was more noticeable.

Get 3-4 feet of tranny line from parts store that's the same ID as the stock vent line. Attach to jug, route hose up to bottom of fuel tank around wires and back down to airbox, cut off excess (leave a little slack so wires are NOT under tension) and attach to airbox. Reinstall everything.
