I agree but a good direct air feed wouldn't be much different.
When I was about 18 I actually sealed a Pipercross cone filter in an alloy box and ran 2 HUGE air hoses to it from the front grill, now that worked REALLY well, but for the effort...... well I never built another hahaha.....

I just ran the air feeds towards the filter.
