Installed K&N CAI cold air intake kit and Borla exhaust on 3.5 EcoBoost F-150

[TheGoatman]

The intake is the same location as the stock unit. So just as cold. K&N filters don't keep out as much dirt as a stock filter as they rely on the oil. Be careful not to dowse the filter in oil as that will damage any sensors in the intake.

No MAF on the ecoboost. Oil away!

K & N are not rated as the most effective filters.

K&N boasts an almost 15 hp gain. Is this realistic?
