Hi, plan is to have cutout to get fresh air. It seems the standard half sausage will also fit as standard from some few non ideal pics I have seen.
Yes this would be mapped.
The K&N idea is purely for looks and may not be practical in the first Instance due to it being project creep.

NOT a k engine but other examples are similar, the bonnet rests on the air filter rather than thd filter sticking through. So same filter whether cutout of not.
It's a Duratec but it is possible to get a tight fit around an IGT who will supply without any logo.
Excuse the white exhaust I was stuck and had to go to B and Q!
