Volant or K&N? Unless there is a better one out there. I am looking for the best looking finished install with a gain in milage. The K&N finished install does not look very clean but maybe it sacrificed looks for performance?

 

aFe Cold air intake looks pretty good and the mfg claims 14 hp gain. Anyone install one on a 2010 5.4 L.

 

Gotts mod will do the same thing and cost you nothing. The numbers they claim are all lies, and most CAI's actually take in warmer air than the stock setup. Google Gotts mod and you will find lots of info about comparing it to CAI's

 

Look into the gotts for sure before you decide to spend the money on a cai. I have it done and even my 4.2 has better throttle response now
