oh i see your thing said to cool... well depending on where you live and what radiator you have in maybe yes maybe no... one thing you could do it just run a good aluminum radiator with a big psi cap and run like a 195F thermostat...
also look at memike's thread about the jeep air box... the only thing i can see with that is a restriction... you want enough air filter surface area as not to restrict the engine = more efficient...
