I love K&N! Great brand American made product. Used it in my old 67 Camaro RS and will use them in my 2013 1LT RS.
I simply just like the look... K&N 69-4523TP Performance Intake Kit (http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
While CAI looks to be the best built and 3rd party tested... It is fairly pricey. Unless your tracking racing your V6 the gain isn't worth the cost in my opinion. But some made that choice and more power to them.
Buy the brand you like and can see the results for. K&N is fairly open about their testing. You can clearly see the benchmark Dyno test they did was open hood in the videos.
