I said you would only get 1/2 of the second e-ram,
When you are running 2 of them then you would lose 1/4 of the total out put. Do you understand now? They are the same number stated differently.
Advanced told me about K&N.
I am used to working on bigger engines (i.e. My old 3.8l V6 and 5.0 V8) if the zetec is a lot different in the way it works please set me strait, but forcing as much air as possible into the throttle body has always been the way to go with larger moters.
Thanks
