Shoot me a PM with your mailing address. I'll send you the other half of the polaris plenum. The plenum can be cut into two separate pieces. I cut mine in half and using a dremel sanding drum, rounded out the airbox snorkel's oval hole. I want to leave one air box stock so I have the plenum if'n ya want it.
Procedure: Place the plenum in the hole. use a pencil to trace along the squashed edges. Careful of not going into the area where the plenum will not seat. Remove plenum. sand. repeat until you have the rounded hole at maximum.
