Do modifications like this impact the air/fuel mixture? For example, is the air/fuel mixture leaner?

Not in terms of airflow, but you are sucking in hotter air with the lid off and hot air has less oxygen and our cars run rich at WOT, so that's how it loses power with the lid off.

The FIPK is worth it (to me) for the induction sound alone and dyno tests posted on some sites indicate a small increase in peak power. Almost any aftermarket exhaust will drown out the intake sound, though.

I love my FIPK, I had the biggest grin on my face the whole way home when I got it installed last year. Plus no guilt of heat soak. I didn't expect any power gains, I only did it for the sound. I did the UK mod to my exhaust and love the pair together.

You must be getting too old, the induction sound on an F20/F22 is a pleasure to hear and I am in my 40's. I have a FIPK on each car.

I am in my 40S too. The sound of th air induction cannot be described in words. Actually, I really like the idea of the lid off because the choice of putting the lid back is always there and it only takes less than 10 seconds to get it done. If I choose the aftermarket intake route, it is kinda point of no return.

You will not hear the induction if you drive like a civilized person, my wife is one and cannot stand not hearing the car breathe when she drives.

Sounds like the solution is "don't let her drive."

I have a Fujita F5 on mine, and it sounds great. It used to be really popular years ago, and wasn't cheap. I can't find them anymore, but if you want a great sound, you can't go wrong.

I would not leave the airbox off if it were me. CAI are not difficult to install. I've had mine on for 7+ years.
