Great product so far. You guys snoozed on the CAI. What do I have to do to get one for trials when you guys release a CAI for this 3.6l v6? :) I had one on my 2014 Cruze 1.4t and loved it! Hurry up and design! Thank you

The throttle is a little more responsive than factory.
Timothy Donihue, Las Cruces, New Mexico
Once again I am completely satisfied with my filter. More horsepower, better throttle response (and even though K&N doesn't advertise fuel economy) I am getting much better fuel economy.

Very good air filter! It gave my car more power and better gas mileage. Very pleased with the K&N store. Also fast shipping.
