I am thinking about the size of air filter I would need. For instance, what size K&N filter would I use? I would like to provide ram air thru the filter. I was considering the conical type filter, but it looks like the size of it may be a show stopper. I am pretty limited in the space available for a filter and do not want to make too convoluted a path to the throttle body. What is the best guess on the number of square inches of filter required? Any help would be appreciated. Thanks, Bill B
