Can you have too much air filter?

Probably not....

Buy the biggest one you can fit in there.

erik i got 1746 for your engine man!! i think youll still be fine with those filters though. i was going to say there is no way im pulling more cfms than you. i am at almost 1500. and i need a single filter which is hard to find. i need something that has a 3.5 inside diameter but not more than 10 inches long.
