Put an EHS controller on today. Also did the AIS plug by putting a 1/2" rubber boot from ACE on the airbox nipple, sliding the tube back on and clamping it. Reason for the controller was wanting to cool down the exhaust. Talked to Eric at EHS for awhile before I ordered it. Was thinking about one of his airboxes since I'm still not quite happy with the interface of the K&N filter (although I think it's a huge improvement over stock). The EHS filter box has a positive clamping system like Yamaha should have used. Anyway while talking to him I mentioned about wanting to get the heat down he said the best thing I could do was a controller and plug the AIS. I know he is in the business of selling stuff but I bit the bullet. I did half a dozen rips up and down my street and there is a very noticeable reduction in heat. Fan did not come on either. Would plugging the AIS alone have done this I dunno. There is also a more noticeable exhaust smell where before mostly what I smelled was HEAT! Anyway I'm happy with it. An airbox will have to wait until next year. Blew an up pipe on my F250. Gonna be drinking cheap beer for awhile!
Eric did mention that cutting off the tube that goes down inside the air filter would increase airflow.
