K&N????

K&N in a 300 I6
Just had put the K&N FIPK Kit into my 1990 300 I6 few days ago . Was expensive, but helps the engine up. I drive K&N in all our cars and bikes, even in my old Ural Russian sidecar bike. The FIPK kit helps the 300 up from my opinion, it revs up more easily and idles much smoother. And it produces a kind of a "growling" intake sound which I personally like. Mileage improvement could not be tested yet, I think there will be a slightly improvement, as with all my K&N equipped rigs.

@Silver Streak: Yeah, I do not disagree with your dyno, but the rough idle on my 300 I6 disappeared to 80 percent after installation of the FIPK. I am on the hunt for killing the other 20% roughness which are left. I hate shaking and trembling gearsticks at neutral on a sixcylinder. Maybe I will have to let it be the truck it is, my other car is a 1993 Mercedes 320 Coupe, Inline six as well, sounds like a cat at idle and goes like a panther up away from idle.
But that is another story.....

K&N
As far as I am concerned, the air intake mods you can do to a 300 I-6 don't do much, unless you have a later computer controlled truck with a mass air sensor. If you don't have a mass air sensor and computer to match the increased air flow to available fuel flow, then you are putting a top hat on a donkey so to speak. Doesn't matter how much air you give it if you are stuck with metered fuel delivery through the old fuel injection system or a one-barrel carter carb. May make a diff if you have a four-barrel carb however. In their favor, the K&N filters are easier to access/clean and replace than the stock setup. Just a matter of where/how you want to spend your $$$.

Anyway, some vehichles need it more than others, and it depends on where the restrictions are in the air intake system, if at all. Even then, it comes down to use the factory airbox or not, blah blah.
Biggest difference was my motorcycle. Ditched the airbox and ran individual K&N's, and there is so much more airflow, it literally wouldn't run. Jet the carbs larger to compensate, and all of a sudden, I'm producing 15% more horsepower. Can't beat that.
Anyway, from the objective reports I've read, the FIPK for the 300 doesn't help a whole lot, but that doesn't mean all K&N stuff is junk.

I can absolutely agree with "benwantland" experiences ! In both our HONDA 750
(model is called "Nighthawk" in the US) I used the K&N Filter. First, it was because of the price, the K&N`s are cheaper than the Honda-Original "paper-with-perforized-sheet-metal" parts (!!!). Second: far to much air, had to be compensated with bigger jets in the 4 carbs. Third: Dyno shows 7.3 hp more. I could compare 2 identical bikes, one with K&N plus bigger jets and the other one without, believe me or not, the difference was really more than noticeable....
OK, K&N will not help always, but I could not feel any contamination of my (very sensible) MAF sensor in our 1993 Mercedes 320. What I felt in this car after K&N installation, was a reduced consumption of about 1 litre less premium fuel per 100 kilometers.
Always had problems gettin my old Russian Ural-iron (650cc,Boxer w/sidecar) kickstarted. Installed K&N ( Triumph model fits...) and a Honda ignition coil. Since then this Russian beast comes on on the second or third hit of the kickstarter, no matter, how long it was parked. Maybe it is the coil, maybe it is the K&N.......
When installing a K&N "Champignon-Filter" to our Daihatsu Feroza (US Rocky), it helps nothing. Consumption raised from 11.5 to 13.2 litres per 100KM. Rebuild it back to original and sold the filter.

Hocky the K&N flows more air. The engine does not have to work so hard to breath. With a carburated setup you may not notice a lot of difference. If you are having trouble leaning a carb out I would definatly try one. With fuel injection the computer can make more use of the air. With either setup it is all up to you. It can make a difference with whichever setup the vehicle has all depends on how it is tuned. If you decide to put it on a fuel injected engine you will notice more difference if you unplug the battery and follow the procedures for clearing the computers memory. If you dont it will be using the old data and will take a long time for the effects to be noticed.

Your right freshman user
the K&N does flow more air, but the stock 300 I-6 carbureted or fuel injected is not engineered to make use of that air flow beyond a certain point. the limiting points are the 1-barrel carb and the primitive air flow monitor that was in these trucks/engines B4 mass air flow sensors were added. I can hook a high-flow air bottle up to my mouth, but can only take in what my lungs are designed to hold...beyond that you're ****in in the wind. unless you radically redesign and retune the stock setup, which was not the question in the first place.

I heard that on the FI models, K&N doesnt help because, even though it provides better flow, it is not cold air intake, whereas the stock is cold air, but it doesnt flow as well, you could always try an aftermarket filter(such as a K&N or Fram Air Hog or something when you replace the stock one, thats probably what I will do next time I change my oil.
