Jeep wrangler 2008 cold air intake fuel efficient options?

i dont think that they ever increase fuel efficiency. My understanding is that the principle is colder air produces more power.

You increase power by increasing the efficiency of the engine. That is also how you increase mileage. A cold air intake increases power because the colder, denser, air charge improves engine efficiency.

Most people who modify their engines do so seeking more power, and as a result they do not drive in a manner conducive to the highest possible mileage. That is also why manufacturers advertise power gains, not mileage improvement.

I can, if I accelerate like a normal person and obey speed limits, top 32MPG in my 800HP Corvette. I don't do that very often (OK, only once, on a dare from my wife) but I sure CAN.

Uh ... no.

I've added many CAs. NONE have done anything for mileage. And I didn't start driving differently.

But, if that's your opinion...
