Question K & N High Performance Intake Kit

Ladies and Gents,

I'm new to this forum and thought I'd post a question.
I have recently purchased a 2000 Ford F-250 Crew Cab 7.3L Turbo Diesel. I've been thinking about installing a K&N High Performance Intake Kit (http://www.knfilterchargers.com/sear...x?Prod=57-2530).

Is anyone out there using this kit? Anything I should know before purchasing one?

Thanks in advance!!!

I've been running that set up in my truck for 6 months now and haven't had any problems with it. There is talk about the K&N not filtering well enough for the amount of air the turbo draws in, so I check my intake regularly and just checked my turbo and haven't had a problem with any dust. The turbo looks good and the tubes are clean. I'm very happy with the setup, noticable different in the the amount of air that is being drawn in compared to the stock box. I like not having to buy a new filter every time it gets dirty, I'm able to clean this and reuse it. I also prefer the oiled element compared to a dry element, dust is more likely to stick to the oil on the filter. Just have to make sure you maintain the filter properly and keep it oiled.
What kind of price are you looking at for that setup?

You might also consider the TYMAR for less than half that. Flows more air than you can possibly use, and there are a ton of satisfied customers. Call Dale at 509-922-8785. My son in law just bought a SuperDuty, and his first mod was a TYMAR intake. It really woke that beast up.

I got mine out of JC Whitteny for $225 plus 4 free cleaning kits.
For the price, I'd call about the Tymar, if I would have known about it before I bought my K&N, I would have gone with it. I'm happy with my K&N, but the Tymar is cheaper and haven't heard any complaints about it.

I've been running the K&N kit on my 97 5.4 for about 6 months and love it. I got it at www.ajusa.com for $235 and it came with the cleaning kit.

In K&N's defense, I read an article that said it may look like pinholes, but there are microscopic fibers across those "pinholes", that is what catches all the dirt.

I'll have to agree with having to wait for them to dry, I can get impatient and I could see having to way for them to dry out during clean get annoying.

Get a Tymar; it's almost the exact same setup(open element) as the K/N, and it also has a larger filter(even more clean airflow)while still only costing $109(When you buy from big names such as K/N, most of your money pays for the "K/N" logo). The Tymar design is extremely simple(only 3 parts including the filter) and effective (you cant buy/make a more airtight intake setup than this). THe power increase gained by the Tymar intake is unbelieveable--I would have never thought that I could have got this kind of power increase by just changing the intake/filter setup. If you pull a large trailer (I pull a 30' gooseneck) the difference in performance between the Tymar and the stock setup will be even more noticeable(the extra turbo boost made possible by the Tymar is awesome!). Last but not least, the Tymar intake is a tried and true product; I have yet to hear one serious complaint.

I've seen these complaints posted at various forums....higher EGT than comparable sealed box air systems due to drawing hot engine compartment air.....Filter exposed to environment, for example, able to get wet or muddy

I've also read a post from the Donaldson representative himself that the Donaldson Filter used in the Tymar draws around 10" restriction while the Donaldson air filter in the Ford AIS has around 8.5" restriction.

After reading those various posts and the reps info, that is why I changed my mind from getting a Tymar to the Ford AIS. I'm not saying this to bash Tymar, I just wanted what I considered the facts to be out there. just my $.02

I thought about that too, but on these engines(99+, not sure on the pre 99's) the air goes through an intercooler, so it doesn't make much difference where the air is being drawn from, it is being cooled before it is forced into the engine.

No offense, but your thinking doesn't exactly work out. I have had extensive training in Heat transfer and fluid flow and one thing I did learn was that the fluid (air is considered a fluid in this context) moving through a heat exchanger will decrease in temperature roughly "X" amount as long as no phase change of the fluid being cooled occurs and the cooling median (outside air temp through intercooler) stays constant. Example for simplicity, Let's say "X" equals 100*F temp drop. Using non-correlating numbers for simplicity, let's pretend inlet air into the intercooler is 300*F with a sealed air box and 350*F for a Tymar, The Intercooler outlet air temperature would correspond as 200*F (sealed box) or 250*F (Tymar style). I'm not being exact here and only discussing heat exchange on a very generic level, but I think you can see the point being made.

Point taken. I understood that it probably wouldn't be as good as a sealed box, so to solve that problem you cut a hole in your hood and insert a hood scoop that directs aire to your air filter. You'll get plenty of cold air coming in then!
