How much did the K&N power kit boost the performance of your recon?

 

At first I didn't notice any difference because I changed it the same time I switched up to my tires which are heavier than stock. But when I switched back to my old filter to see the difference it made, I noticed I huge decrese in power with the stock filter. So it does make a difference, especially with the airbox lid off. I recommend keeping the stock foam filter and airbox lid in case you are going to mudding.
