i love my k&n i have one for my 2001 f250 works amazingly yes its a mess if u put way to much oil on it if u put the right amount on it you will be fine ull get a little oil on ur hands but it comes off better millage and saves you a ton of money in the long run just saying ive never heard anything bad about k&n warrenty is next to none

 

On the rear pop the clips. Pull up away on the rear section that connects to the turbo tubing. Then pop the clips on the front snorkel that goes into the front support and pull it up away from the filter element. Now grab the filter element and pull up. Check the two mount studs on the old element there are inserts that make it fit tightly into the battery cover/filter holder. Remove the snorkel so you can cut off the longer portion. This will make removals and installs MUCH easier. Attach the modified snorkel to the filter. Install the new element. Attach the rear housing. Done.

The modded intake snorkel should look like this.

I just took the entire front off of my air box about 3 years ago, no issues so far. Why suck through that little hole when you can take advantage of the entire opening?

 

What was your mileage before and after?

It works amazing in what regard? What are you basing this off of? I've never had an air filter actually save me money. They claim 1,000,000 mile warranty sure, but what exactly would you need to have warrantied on an air filter?

 

Pick any one from the link below:
2003-07 6.0L Ford Powerstroke Diesel Cold Air Intakes/Filters

Cheap end: $200 High end: $481

OEM filter dealer cost: $76

Now here's the math. Ford recommends inspection of the restriction gauge every 7500 miles and filter replacement if needed. So let's agree the OEM filter will last 15k so it's getting replaced at least once a year.

$200 (cheap) / $76 OEM= 2.63 You use roughly 3 OEM filters for over 37K miles of driving.
$481 (Volant) / $76 OEM= 6.3 You use 6 OEM filters for over 90k miles of driving.



To me OEM works and works VERY well. There's no need to go aftermarket.

 

I got my AFE stage 1 intake for free, then I went ahead and paid for the AFE proguard 7 filter to drop in it, and the cost of that was about the same as a stocker, so for me it was a no brainer.

 

I knew a K&n CSR and when I told her that my new K&N airfilter lid on my '67 Mustang () was deforming, she told me there was an upgraded design that I could get FA-REE. So, because mine structurally failed, it warrantied.

Because I only took the front off of my box, the $75 I paid for my AiRaid paid for itself the first time I washed/reused it at the 7500 mile interval. My restriction gauge is either broken or that AiRaid flows really well. Either way, I bought my 6.0 with the intention of seeing 500K or more on the odometer. Why not? I've had the '67 for 18 years in March.

Oh yeah, the Army used K&Ns in the electronics cooling air inlet system on the AH-64A. Too bad all parts had to be accounted for in teardown when I was working at Boeing making them into AH-64Ds.

 

Attached is my "cold air intake".
