Replacing this is quite simple. First, you want to pull off the metal heater hose. Mine was so badly corroded, that it just broke off at the base near the exhaust headers. But I think it just pulls out. You will not need to worry about a plume of hot air, since it will only rise naturally though the opening. Nothing will be above it anyways. Then remove the valve and the ducting between the elbow in the pontoon, and the air cleaner. Now you want to go to an autoparts store and get a 3 1/2 inch diameter round fresh air intake hose. It will be a snug fit around the air cleaner, but an oversized fit around the elbow in the pontoon. What I did for this was simply cut off the built-in connecter on the end of the new hose, and used a ty-wrap (or a hose clamp would work) to secure it down. Now your engine will sound a tad louder (if your paraniod enough to hear that) and you should fell slightly more kick at higher RPMs. I would take pictures of what I have on my car, unfortunately it is off of it right now along with the entire intake manifold while I replace the water pump and give a good general tune-up. Good luck.
