I just bought 2 cone filters from autozone. I put 1 on both the pipes coming from the box, and left the bottom of the box their for support, and also to keep the valve breather or watever in current setup, while allowing some of the cold air to flow in from that measilly 1 inch by 3 inch slit in the front of the engine compartment, while i didnt check to see if it improved my idle, during a test drive, it definately revved a little faster on the top end. ( if thats not an oxymoron on a 300-6) But i have yet to see if i get power loss if the engine itself heats up. I think my truck is running rich btw because my exhaust just smells like it, any ideas, maybe thats why this mod is giving me a lil more bawls.

K&N filters do flow more air than stock, but the engine can't use it so it's a waste. K&N filters also aren't very good at filtering. Any filter I can see through is a joke. I don't care what their propaganda says, they are lousy filters. Even if it was worth 5 hp I would still run a stock filter that would keep the dust out of my engine.

my recomendation is to go to autozone, and buy 2 cone filters from there, the ones with 3 inch intakes and a clamp, and take to top off the airbox, and connect both filters, 1 to each intake pipe. I KNOW! that it increases airflow as my truck sounds much better at high end, and it seems to have more power at those ranges too, (the ranges consist of about 22 to 28 in first with stock gears, and 38 to 44 in second). I left the bottom half of stock intake on cuz its connected thru a hole 2 inches by 3 inches to the outside air through a hole in the grill. Next thing i do would prolly be build a stand to hold them up, like sheet metal with 2 three inch holes in it to hold them at a set angle and line them up ( more acstetic (SP?) even though it looks so pimp with 2 cone filters and they are pretty much lined up neway. I might make a ram air and run it up from under the truck.

are u sure ir made a difference or is it in ur head? just because its making more noise doesnt mean it really did anything worth while. when i installed my KN panel filer all it did wa give me a SLIGHT throttle responce increase but shortly after it felt no different than a paper filter. good for u that it made a "difference" but ill stick to my good ol fashion paper filters.

Every time I would post anything against these wonder filters I'd catch hell. Glad to see there are still some out there who see it for what it really is.
The I-6 is a low rpm engine and cannot in any way take advantage of the "free-flowing" characteristics of oily gauze filters.
Ain't nobody in this world can "feel" the difference of 5 hp!!! No one's butt is that sensitive!! (5 hp is generous IMO). It's all imagined!

im not using K ann N filters or watever, these are just cone filters, 20 bucks a peice, trust me the top end power is increased. if you could see the setup youd see why. With the stock intake, the air is coming from a 2 X 3 slit in the front, some say that its almost ram air, but its facing away from the grill, its facing to the right (if viewed from front and its located on the right. I go from a 2 X 3 slit to massive filters, i promise you. My truck would rev to 28 in first, but now it like... MORE MORE MORe type thing. Maybe this is just specific to my truck, and maybe it has to do with my free flowing exhaust, but the added power where i need it is there. I will tell you a definate answer as well as a ET gain in a week when i get back to the strip.

If your truck will only pull 2800 rpm in 1st gear there is something seriously wrong with your engine. I shift at 3800 in 1st, 3500 in 2nd and 3200 in 3rd. My dyno sheets all look identical no matter what kind of intake is on the truck. I doubt your high flow exhaust is any better than mine. It doesn't matter if you feed a garden hose from a 5 gallon bucket or the Pacific ocean, the hose is still what limits the flow. Same story with the head and valve timing in the 300.
As far as ET gain is concerned, not everything is as it seems. There are too many variables at the track to tell any difference unless you are making huge changes. You need to spend some time on a dyno to see any increases you will get with a certain modification.

But they don't just show up at the track and say I'm going to run whatever time. They make several passes the day of the event before the racing starts so they have a very good idea of what to expect out of their car that day. Then all they have to do is estimate how much to change their dial in each round. They also use a weather station to tell them what the density altitude is and what the humidity is. I seriously doubt any of that equipment will be in use during the testing we are talking about.

Yeah, but I'm just saying it's entirely possible to notice a small difference in power if one wanted to test it that way. Especially with something as simple to change as an air filter or intake setup. A couple of runs each way back-to-back, and it would be apparent whether a worthwhile difference was made. You don't need a weather station to test an air filter.

Right you are
Yes, your truck will be a little peppier going over to a cone filter or FIPK setup on a 300 I-6, compared to the stock/crude air intake setup. I had a muffler shop fabricate a Y-pipe to join the two black intake hoses into one and then stuck a K&N cone filter on the end of the one pipe. It was peppier but it also started sucking gas...which is NOT GOOD these days. I'd rather run the stock setup, get better MPG and thumb my finger at OPEC cause I don't have to stop for gas every time I pass a station.

K&N is a creative way to waste money. modding a 300 is like drag raceing a ice-cream truck...pointless. i've sawed my muffler of and ive taken my air filter off so that im just suckin in the air we breathe with no filter. i felt NO increase in power. open exhaust and no air restiction into the motor due to air filter and i felt no power increase. I'd take a K&N only for free and if i were bored and felt like installing it.
the inly way to mod a 300 is to mod the motor itslef.

AHAHA i wasnt talking 2800 RPMS i was talking 28 MPHs. At night when its nice and cool, i can loose the back end in first going around any corner as well as in second. When its cooler outside, and the engine has been sitting for a bit ( IE when i first get off work) i can push 30 MPH in first, 50 in second, and 3rd i have no clue, cuz i dont have a tach and wind noise starts factoring in, i know it does 67 tho, and 4th, hell it carried me to the peg before i got these mods.
