Worth installing a CAI

Hey. I'm new to the forums here. And had an immediate question

I'm wondering if it's worth installing a cold air intake on my new truck 6.7L 2015. I will not be doing a DPG delete any time soon for DOT reasons. They check it often in my area at the scales.

I would want this CAI mainly for easier Maintenance. 5 days a week all day I pull a trailer and on a lot of dirt roads. I have to change the filter every oil change and I service at every 5000km

So the savings is in question aswell as power and fuel economy of course

Won't do anything for you in my opinion. Save your money.

When oiled correctly they actually rob power and fuel economy. Not to mention most actually aren't a true CAI since they pull air from the engine compartment. Your factory intake in a true CAI.

And to get the cold air, it has to be way down low, which is where the most dirt is..

The factory spends thousands of hours testing and tuning these things to perfection, and right away, people want to rip stuff out, and replace it with things that have NOT been well engineered, or tested for thousands of hours.. Don't mess with a masterpiece, lol.

Stock here also. Nothing will be gained from aftermarket, and possibly too much dirt going through the filter. Also COULD negatively effect your warrantee.

I bet you the stock air intake on these, is rated for much more HP than the engine can currently deliver anyway.

That's the key isn't it? If the turbo pulled more air than the factory filter could flow... Ford would just stick a bigger filter in off the line and bump the HP rating after removing the restriction. They're fighting Dodge tooth and nail for paper HP and TQ ratings, why would they let an air filter be the limiting factor?

If K&N really worked as advertised, Ford would buy a million of them in a heart beat, probably put a badge on the side of the truck (Chevy and Allison anyone?), and market the crap out of it. But Ford isn't going to pay $85 piece of paper and some rubber that does the same, if not worse, than what they get from Prime Guard for five bucks.
