I am thinking of purchasing a cold air intake from JaguarXP.com for my 97 XK8. It looks like they're using a K&N filter, offering a reasonably priced kit. When I called them, they said that the modification usually doesn't cause any sensor codes or failures.

Has anyone else used this kit that can offer feedback?

Has anyone else used a similar product that I should consider?

I am interested in a little more performance, but I don't want to do anything to harm the car.
