police interceptor air intake

[joethefordguy]

I've read elsewhere that the Ford Police Interceptor engine horsepower increase is mostly from opening up the air intake.

can anyone comment, verify, etc.?

I believe the 2004 - 2011 used the Marauder air intake box. You may check the parts book to see if the heads were different too. The computer was tuned differently as well as the EGR.
