Air Box Mod Idea?

It doesn't make sense. But that's emissions for you. Same reason EGR routes 1500 degree exhaust gases back in to the intake.

If mfg's wanted to make the most powerful and efficient engines from the factory, they'd all have CAI's with no resonators, no EGR, 160 degree thermostats, oil coolers, piston oil squirters, high flow cats, long tube headers, true dual exhausts, electric water pumps, electric power steering, direct injection, and variable valve timing on both cams.

I apologize to the OP for taking this somewhat off topic.

Ya i hear that. Poor choices IMO.

For some of those, its mostly to make it a livable car as well. As for the long tube headers and high flowing exhaust comes the price of loud exhaust. why they run hot air back through the intake? look back to the old carbed engines, its also to speed up the engine warming process. running 160F T-stats? im pretty sure Heaters would only get warm and not hot on the coldest days. Ive heard electric power steering leaves a little to be desired in the road feel department as well. Engines will always suffer a little in performance for the comfort and lower cost to the consumer.

I could be wrong on some of those though. Just my thoughts.

Nah. 160 is fine for cold climates. I ran them in all of my Ford Contours and I live in WI. Even with a broken thermostat that is stuck wide open, the air will still get a little warm.

You're right on electric power steering. It's not there yet. But it's getting there. Just look at how throttle by wire has progressed. I can barely tell most of the time.
