Cold air intake for the Ecoboost? Good idea?

So I was planning on putting a K&N air filter and cold air intake on my transit (with the 3.5) whenever it arrives. However, based on some other posts I'm thinking this isn't necessarily a good idea. Has anyone done this with good results (more power, better fuel economy etc..)? Are there other upgrades that are beneficial and don't void the factory warranty? (I'm really more of a "wannabe gear head", so my assumptions for what is good for an engine aren't always correct) Thanks for any advice!

If you do put one in, run it for a bit, then rub your finger around the intake pipe just downstream from the filter. You'll find it coated with an oily, gritty residue. Not exactly what you want to be feeding your engine.

Filter aside, there are good oil free filters(uni) that would work well.
What is the general consensus on an intake. It could eliminate the wet air filter problem.

Uni makes a good filter. They are oiled so they would not absorb water, and they filter finer grit with less restriction than a K&N. Unfortunately, they are better suited to small engines and race applications, as the volume of dirt needed to be captured in a car sized motor means you would be servicing them a lot.

There are oiled intakes for hundreds of vehicles. I'm sure the air filters and the oil won't hurt the engine.

I would worry about the water, though. The water pours in and splashes all over the engine and during rain and puddle splashing.

Exactly- K&N's let through WAY too much dirt.
Seen it too many times, cost me a $500 turbocharger on my 96 7.3L Powerstroke about 15 years ago.
ONE grain of sand hits a 200,000 RPM turbo blade it chips it. Then it is out of balance and will self destruct eventually.

Let's forget about the filter for a second, there are non oiled filters that work.
Let's talk about the cold air intake and the potential to fix the wet filter problem.
What's your opinion/research you've done in applications for the transit.

Where does the intake air come from stock? I thought most new cars already had a pipe running into the fender / behind the light - effectively already a cold air intake.

Just went out to look at my current vehicles. Both - a '15 NV200 and a '98 S10 - hardly high performance vehicles - came that way from the factory. In the case of the Nissan the duct seems a bit small, so I could possibly make a case for installing a larger intake so it can breathe better but otherwise I don't think an aftermarket system would help much.

In the specific case of the Transit, an aftermarket filter box could certainly be a benefit.

I haven't received mine yet, so I can't go out and look at it. But I'm confused how we have a filter element that gets flooded with water. And if the intake could be an easy fix and not worry about it any longer.

K&n filters do not let sand in. Anything over 10microns is filtered and anything smaller won't hurt your engine. Read the info on their website. This anecdotal evidence proves nothing.

My grandma smoked till she was 90 so smoking is cool, right?
