will a K&N do anything on a 3.0L?

[bluebombersfan]

I put it on my old 2.3L but never noticed a difference. Someone told me the reason it didn't do anything was because it had the same air filter as the 4.0L, which makes sense to me. So I imagine it would work best on a 4.0, so the big question is will it do anything on the 3.0L?
You can tell when a k&N is working by the deeper voice the engine has when you slam the gas down aswell as the suction sound which is pretty cool.

A search on K&N web site under HP Gains shows even K&N says it won't do anything.

Cool sound is about all you'll gain, but it's great for impressing the girls.

The K&N cuts down on the air filter costs. By the time that you reach the cleaning interval for the K&N filter,you will have changed a regular filter about 4-5 times which costs almost as much as the K&N besides K&N has the Million Mile warranty. Also the neat sound.

If you had a carb it would make more of a difference. Not much of a change in anything else.

I just saw a show on tv some muscle car show and one of the things the pro's did was put on a K&N on a f150 to increase some hp, These guys were not amatuers, Then also here on this link aswell, (truck trend).

Also like mentioned before I think it depends on the vehicle, On my old accord I could hear it sucking air when I punched the gas, but I put it in my 2.3l ranger did absolutly nothing probably because it already had the same air filter as th 4.0L.
personally I find if i buy one I can tell if it will work or not by the sound, If I can hear the suction when I punch the gas thats a good sign, if not then I think it has to do with the fact that the original air filter designed for the 4.0 is already oversized in the first place, and this is what I want to know.

i put a cheapo parts store cone filter on my 2.9 and it accelerated much better afterwards. as far as hp gains, i dont know and i dont really care. the acceleration gain was well worth it

The ACCEL Kool Blue filters are every bit as good as a K&N, and are usually half the price.

I truly believe that doing a dyno test on a 4.0L with or without a k&n would easily show a 3-10hp gain with it on, and probably no difference on a 2.3L since the filter is oversized for the 2.3l in the first place. You guys must agree on that right?

Don't know about that, but I know the 95-97 and 98-11, all 3 engines used the same air filter box and filters.

 

[bluebombersfan]

Thats what I was getting at, To get performance gains would be to put it on the 4.0 liter since thats the engine most likely with air filter box same size as the 2.3. I would not be surprised if the K&N on a 4.0l would show 5-10hp increase on a Dyno, And do nothing on the 2.3.

"I'll believe what I want, just don't confuse me with the facts".

Check out the K&N web site on HP Gains. The drop-ins don't (usually) add anything but some applications will show HP gains with an air intake kit which includes the intake tube. The RPM necessary (higher flow) to get the gain is important because that determines practical street useability. The kit (with a smooth bore intake tube) is probably the reason for the gain, not the K&N filter, as it reduces turbulence in the intake and aids laminar flow (necessary with higher flow engines like the 4.0L).

K&N is also in the business of blurred marketing to buyers (the gains from product A naturally extend to product B) to sell unnecessary filters.

You believe wrong...

 

[bluebombersfan]

fair enough

I still go with K&n, I have the cleaning kit from my last ranger already so I am content with just having something I can wash and reuse.
