K&N Air Filter?
I am thinking of getting a K&N cold air kit for my 2007 Chev 2500HD 6.0L gas. I would like to here from those that have used them or any issues with these filters. Thanks

I'm still confused as to why these are referred to as "Cold Air Intakes". We all know that cold air is denser and provides a better combustion charge so it's advantageous to use cooler intake air.
When GM designed the stock intake box on my '01 they ducted it to the fenderwell. It is designed by the factory to draw cooler air from the outside, not hot air from the engine compartment.
If I replace my stock airbox with this:
I am now drawing hot air from under the hood and not cool air from outside, so whatever flow increase I see is going to offset by higher intake temps. These should be called Hot air intakes.
If I am used car shopping and see a K&N filter installed it's a deal breaker. No telling what other fugazy mods and abuse the vehicle has suffered.
Race cars use K&N filters. race cars also put 100% nitrogen in their tires to keep pressure more stable as heat builds. Neither offer any real world benefits for your average truck or car.
