I own a 2003 F250 with the 6.0, it is bulletproofed and straight piped. I bought it with a K&N intake on it and filter, and I've had the truck for 10 months. Lots of work has been done but I don't make tons of money so the process is slow. I had no idea that my air filter was very dirty, and I feel stupid for not noticing earlier. It is a K&N but is completely black and has a few places where the metal mesh around it has worn from rubbing. Should I try and clean it or just but the bullet and buy a new? I know these intakes are bad but I don't want to replace it with stock right now due to money and not being able to find a stock intake. Thanks for the help

 

Stock will be cheap compared to a new turbo or engine. Your money and your choice.

 

eBay $150 ish can get you the stock set up. New turbo ballpark $1000? Not sure on that as I've not priced one, but you get the idea. A new K&N isn't real cheap rather, so I think you may be between a rock and a hard place, sorry.

 

First choice ...would be replace with stock setup

second choice ...if money is that tight, at least buy a new K&N filter for now..& oil it. I don't know if they make the covers for the KN filters like for atvs to keep sand out...might wanna check. Save up and get rid of that thing.

 

Ok guys, I'll give you more to talk about...

Please excuse the dust!

 

Well, here's my feelings on KN....I run one on a turbo charged Buick V6. It is located right behind the front bumper, with a front spoiler air duct feeding it. That car rarely gets driven, and when it does....never in the rain, and never in dusty conditions.

I will not run one on my truck because they only Filter butterflies, frogs and small rocks.... and I wouldn't recommend anyone with limited funds to run one on their truck.

 

Livinglarge, your K&N filter does not look like it is disrepair. The OP indicated that his filter was in need of replacement.... There, talked about it!

 

Lol, all I can say is the stock box is good to about 500hp

 

Does the K&N retain the filter checker found on the stock units? If it does and it doesn't show too much vacuum, I'd leave it alone until I found a stock unit to go back on. Being dirty might be a good thing if it acts more like a filter that way. If you have to clean it be sure to use a K&N filtercharger kit and follow the instructions to the letter.

 

Yes siree! A K&N will definitely allow more air in. Do you know how much hp you are getting out of it?

 

Haven't put on a dyno since all the work, but it's on my to do list for sure. Biggest difference to me was fuel system upgrades, injectors, turbo, etc. I first thought my mpg's were going to be in the toilet, but not at all. Like Ive said very pleased with the results so far and she can still be a daily driver. If I had to guess I would say somewhere in the 550 plus range with enough torque to snap a neck lol.

 

About the vacuum gauge filter minder, that's number two to replace next. When my engine was rebuilt earlier in April they forgot to plug it back in the intake I'm guessing and I found it hanging on the frame rail last week by the wires, cracked and busted open, not good at all. I don't see how it would come out on its own as it fits very tight in the intake, and yes there is a place for it. I rigged it up so no bad air is drawn in but the actual gauge no longer works. I would replace the intake back to stock intake but right money is tight and this truck eats up money quick and other things are more important than a vehicle. Times will get better and i just started another job. This truck caused me lots of trouble and I got scammed when I bought it, guy said many things I found later were not true, and when I had it checked out no one found the problem, then I found them only after I paid the man for the truck and he was long gone... I completely agree with everyone on the stock intake, I plan to get one after I replace some other much needed items( batteries, differential serviced, coolant flush). But just having ANY clean air filter is better than this one, you can't even tell it is a K&N it's so dirty. I know lots about cars and its my job to work on them everyday, I don't know how I let this go unnoticed and I'm really embarrassed by it actually, since I'm usually very particular about my trucks.

 

I want drive that Buick! I got to drive a Grand National years ago and it WAS Bad to the Bone!

Sorry I had to comment...

 

Is the K&N attached to the intake box with a hose clamp? You might take the filter to napa and see is they can match it up with something that will work....I dunno, just throwing out ideas.

 

Way back when I put a FIPKII intake on mine. One weekend at the track, vs the stock air box, made a believer out of me. I now honestly believe K&N is full
of it. My truck was slower with the K&N. Negative performance gains, and higher risk of hard parts damage, no thanks. It didn't work for me. YRMV.
