K&n or airaid air intake?

+1 - stay with stock air filter box/tubing. I have always had success with Green Filters - works great on the Raptor too. Cost was only $40!! Go to the Green Filter website and you will see how they outflow everyone. On my 10 CTS-V, I switched from K&N to green filter and picked up more power.

Not sure if I want the whole filter exposed. Leaning more towards the airaid with a pre-filter. Will also check out the green filter

No need to check anything - RETAIN the factory stuff and just put high flow filter in. Aftermarket CAI has been proven to not make any added hp
