K&N air intake kit?

[AllanD]

Okay we're going to say a Mcdonalds straw. Can't believe I had to dumb it down that far. I'm not saying you cant breath through a 1 inch tube easily. In my example I'm saying its easier with two straws, performance fiter, then one, paper filter, and the easiest way is with your mouth wide open A.K.A. no straw/filter if I can say it like that and everybody understand me.

I can't believe I'm wasting time dumbing this down, if the intake tube is adequate (it is) using a bigger tube ain't gonna do shit.

Trust me, the factory really is looking for fractions and improving things ain't gonna be that easy.

Bear in mind that a 2.9 makes more power than the last of the carb 5.0's did
and the 4.0 makes more torque....

I fail to see how you can think there is all that much left to gain.

dude i get it easier it is suck air in the easier it is for the engine to make power

I was comparing the straw to a filter, not a tube. Everything I said before still applys to a factory style performance filter and factory style paper filter also.

Like I said before your vehicle run what you want on it.

here is my opinion...
number one:
the government places restrictions on our automobiles here in the U.S. with all this pollution crap so therefore the auto makers are more worried about the car being legal than to have top performance from the factory.

number two:
anyone who has ever tried to light a match in outer space knows you need oxygen for fire, and an internal combustion engine needs fire to have power. this means that when you have more oxygen you can have more fire. the higher your rpms go the more fire you have which means you need more oxygen. a k&n filter will allow more oxygen into the engine, so when your turning higher rpms your likely to have more power. anyone can say that the stock intake is just as good as any performance intake... why do drag racers run no airfilter as our friend bob ayers noted... because they are looking to burn a whole lot of fire/rpms and they need a whole lot of oxygen.

number three:

the claims that running a k&n making the inside of an engine dirty from dust...ect. is actually really funny b/c anyone that nows the the basics of engines knows that there is this thing called carbon build up inside of the combustion chamber (the place where the air goes to meet the fire). a particle small enough to get through a performance filter more than likely won't matter anyways b/c your engine gets gunked up over time from burnt gas (carbon build up), which is why its good to have a good maintenance schedule. and for all of those k&n haters. i have 225000 miles on my engine and it is still running really strong. so a little dust never hurt nothing.

to answer your question if you have the money to spend i say go for it. i have a k&n intake with no regrets i do notice my truck seems to pull my boat a little easier and maybe a mile or two better on the gas mileage.
good luck with your quest for power.

AD, some people just don't get it!!!! Instead of a straw analogy, maybe they can understand this:

Let's say an engine pulls 600CFM of air at MAX RPM, and WOT. OEM intakes & air filters are over designed, to allow for blockage from dirt, so they will flow 800CFM of air. Because of the holes in the filter media used by K&N, they will flow more air, 1000CFM. Now, since the engine only pulls 600CFM, it's still going to pull 600CFM with the K&N! One thing to note, if you increase the diameter of the intake, you won't get any more air, but the velocity of the air will be decreased, which affects the accuracy of the MAF sensor.
And, you also pull in hot air with the K&N intake, which is less dense than cooler air.

K&N filter media:

OEM paper filter media:

seems to me that.. from those lovely pics. the K&N lets in sand =>

I never said you will pull in more air I said it would be easier to pull in the air. My straw analogy still applies. Performance filter has bigger openings (two straws) and the paper filter has smaller (one straw). I read the K&N fiter write-up a month ago and then came up with the straw analogy.

K&N is only one performance filter and it uses oil. How about a performance filter without oil. Mabey were all looking at it wrong. We are comparing fiters with and without oil. Compare two without oil and vise versa.

Exactly!!!! This is why people that use K&N's report much higher levels of silicon with UOAs. This is also why there are reports of "turbo dusting" from
using K&N filters, and probably the biggest proof that K&N's pass a lot of dirt,
is from K&N! Check out this Precharger Filter, recommended by K&N in "very dusty conditions":

You missed one important point! It is a known fact that the dust ingested by an engine using a K&N air filter will be mostly silicon. Silicon is over a magnitude higher in hardness than carbon! So, silicon is way more abraisive, and causes more wear than carbon. Check out this element hardness table:

This is also the reason for turbo dusting using a K&N!


Also, a post from Alland regarding K&N air filters:


"My brother LOVES K&N filters.
He will NOT use them on his own vehicle.

You see he is a Ford Dealer mechanic.

K&N filters make him more hours and thus more money.

Especially on the turbo diesels

Ever seen a turbo diesel that's bee run behind a K&N?

It's fugly."

I'm not worrried that much about dust. my truck is usually on the road, i go wheeling every now and then but even where i go its not dusty so there is no real problem. right?

Shady, a dragster's engine only has to last 1/8 or 1/4 of a mile.......So,
Most dragsters don't use an air filter at all!!

As I have said before, you don't have a clue as to what you are talking about. You take pretty pictures, but that's about it. You don't have any background in automotive building/repair/modification, yet you come on here as an expert in everything automotive. You repeat things you have read and heard, much of it false information, no hands on. Working on a 69 Ford one time doesn't qualify.

If you were to attend a drag race you would see many more street machines than dedicated dragsters. Many of these engines cost much more than any OEM engine. They are street driven, so only going the 1/8, 1/4 mile scenario doesn't matter.

If these guys want to use the filter, so what. The question was where the product could be purchased. He wasn't asking for a disertation on the merits the performance of the product. But these posts always degrade to this type of bs. If he wants a K&N, so what, there is nothing saying he can't have one. There is no way to know for sure whether or not the product will improve his vehicle, or hurt it. No way at all. Many use this kit for reasons other than air flow, so why all the bs?

The Rolls example is pure and simple stupid. It is a rich man's toy, nothing to do with the subject at hand proving nothing.shady

Since there is no performance advantage, why would you want to take the risk of damage, and empty your wallet?

Caught you Shady.....in your original post, you said dragsters, now you have changed it to "dedicated dragers"...........The point with the Rolls dragster was NO AIR FILTER at all Shady!!!!


Looks like you haven't changed Shady.............Your trying to weasel out of this one like you did when you were wrong about the GROUND on the secondaries of a DIS coilpack!!!

Again, you lie Shady............not true at ALL!!!

I have experience in engine/automotive repair and rebuilding, but I don't do it as a profession!!!

I'm an EE by profession.......

Bob... man you missed my important point...i have 225000 miles on my engine (with a k&n, oh!!! its a miracle) and it is still running without a problem and no rebuild. also the wear factor of a engine lies more on the side that the oil goes in you know that why it needs oil...to reduce friction which causes wear. and i don't think that k&n was saying that dirt comes through the filter by coming out with a filter cover. i'm pretty sure they are saying it will help reduce the number of recharge services that you may have to perform on the filter.
