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

Notice how all of these miracle products claim horsepower gains of "UP TO" xxx horsepower. Never an actual number..It's like none of the engineers that build these cars know what they're doing. If it's that easy to gain power why don't the factories use them?
