[TUF-427]

Merv,

I think your filter is below the bonnet line anyway in a harrison so prob out of the airstream,

but the air from the thermofan could also disturb if their this sensitive and it looks like they are...

Brighty also has a Stage2 airmeter which has more resolution for bigger injectors 36+ so could possibly be more prone to this than the stage 1.

I think an internal baffle inside the filter is the answer as you still want the benefit of cold air from scoop if possible.
