Cleaned the K&N air filter tonight....bugs!

ok guys...please don't beat me up. I want to learn. I have read, read, read lots of threads here.

Why is the CAI thing so much better that stock!

I get it, that the cooler air intake is for better engine performance.

But, the stock intakes ARE in front of the radiator. Both sides.

I see the Needswings are even closer to the grill though.

I am a grasshopper....you are a rock.

Thanks for everything I have read here. I'm am here to stay, can't see selling my XF.....ever. Love it!
