I've used a drop in K&N Filter in the J for many years and I've never had a problem.
The air intake on the J is very good as is. Installing any type of CAI or custom underhood intake is a waste of time and money. You'll get no horsepower or mileage gain. Its been documented by previous J owners on this sight who've dynoed their cars and posted the results online.
In fact in some cases their horsepower or milease decreased from factory spec.
Perhaps Q45 tech can chime in.
If you want a handful of horsespower and a bit better mileage save up your monet and get yourself a JWT popcharger for the J.
