Tonight I slapped an air hat from a Durango onto Charlie...and Charlie couldn't be happier with how it turned out.
The old air hat
The new air hat installed
Another installed picture
The only major modification needed to make it fit
I did not notice any difference but its getting more air flow so I am happy with it.
air hat from JY - $9.50
longer bolt for hat from Canadian Tire - $1.10
rubber vaccuum caps from Lordco - $4.95
