Removed the aftermarket air filter, installed the OEM v10

[GON]

My 2002 F350 6.8l V10 had an aftermarket air filter installed when I purchased the truck. Airraid was the aftermarket system, now owned by K&N.

Very tough time getting a comparable replacement air filter, with a 4 1/2 inch opening. Lots of research, very pricey from K&N for a oiled replacement filter.

Took some work to locate the OEM air filter bracket.. found the bracket on eBay, and earlier purchased an OEM air filter housing.

Got it all installed this morning. Would love to see independent significant studies in these aftermarket filters. With cafe such a big thing, I suspect the big three would go with these aftermarket filters if they actually made a measurable difference.

I always thought the V10 OEM was plenty big and did a good job for me on my 2003 F350 that I had.

The only good thing about aftermarket IMO is they free up space in the engine bay, which I appreciate even just for cursory visual inspection of FEAD or coolant leaks or rodent nests.

Beyond that they're mostly junk and fitment is always poor. Something looking suspiciously like that AirRaid almost rubbed through a brake hard line on the wife's '08 F150:

Nice work. I would have ripped that aftermarket junk out on day 1.

There are some, I put some graphs in another K&N thread but can't find it. They don't filter as well, flow a wee bit better, and show small power gains at high rpms that nobody drives at. If you live somewhere humid, only drive on pavement, and keep up with the maintenance they don't do any harm. And you get intake noise for the butt dyno.

I had a K&N on a 2005 STS V8 and honestly the intake noise was almost worth it... I eventually felt guilty and put a regular paper element back in and it always sounded lame to me afterwards. Engine had a timing chain failure and I wish I'd just let it go to the grave with the K&N in it. haha

what junk good man and good job replacing with an oe airbox.

paper filters FTW. i have a donaldson 6637 on a CAI kit for my Silverado. looking back, id still have the factory air box in it. they’re ducted through the fender, aren’t restrictive and my 02 came factory with a restriction gauge (resettable type).

if i could find one for decent money id probably go back.

i tell everyone to stay with an OEM style paper filter as there is simply no reason to deviate unless you’re highly modified and the factory air filter is a restriction on power.

My work truck from 2002 to 2013 was a 2002 F-350 with the 6.8 l V10.

Other than using a litre of oil between changes, it was a good truck for us. No mechanical issues or breakdowns in the > 250,000 km we put on it.

We often towed a heavy flat deck trailer with three ATVs on it. No problem at all.

Fleet Services would not have been impressed if we'd fitted it with an aftermarket air intake and oiled filter.

I do have a study that I saw online, will try and find it and post back.

On my 2021 GMC Canyon with a 3.6L I kept the OEM airbox but routed a new intake tube straight from the throttle body to the airbox.

The factory tube is part of the engine cover. A bunch of twists and turns and resonators to keep the sound down I guess.

Removing all that and replacing it with a straight tube cleaned up the engine bay and gave me a bit more room. And it has a bit more of a growl when you get on it.

Where did you buy the plumbing for this project?

I had a Volant unit on my 5.7l Ram. I installed it because it uses the Donaldson Powercore air filter, which seems to be excellent! The only time I would consider using some sort of K&N style (insert whichever brand you want) is it it was a performance turbo application which was being modded for higher performance. Other than that, I would opt for better filtration and clean intake over negliable higher flow.

I was actually contemplating getting a full kit from one of the name brand Cold Air Intake companies but the price was a bit too steep and I was probably going to take a hit in filtering efficiency.

I stumbled upon Volant as @Johnny248 mentioned in the post above that offered an upgrade to a Donaldson Powercore air filter. After reviewing their diagrams and instructions it dawned on me that their tubing would work with the OEM air box.

I bought just the plastic tube that went from the throttle body to the air box from them. When I got it I measured the diameters of the airbox and throttle body and bought the necessary tubing transitions from Summitracing.com.

I think it cost me about $100 all said and done. I didn't do it for performance. I hate engine covers and un-necessary clutter like air intake resonator boxes so I just wanted to get rid of all that for a cleaner engine bay. I probably picked up 1.5hp at peak power output....but it sounds more like 10hp!

Like the way you operate lol something I’d do myself.
