Cold air intake, need some advice.

[BlackBII]

This thread =

Look guys, all we are trying to say is that the paper Filter itself is not restrictive.

Therefore, changing to one that flows more air will not increase power.

The engine is going to pull the same amount of air whether it has a paper filter, expensive filter or no filter. You are not changing anything on the motor itself!

Do Ric's test, and you'll see what we mean.

well i just stated that a minute ago, i know ur not calling me aknow it all, like i said id be the first to deffend you. and also as i said i noticed a difference from my cold air system but my brother put one of his ranger and he felt a difference but if others do not then wut can u tell them. if its in my head then o well i feel better about my truck. if not o well also. but their right about the amount of air going into the engine.

 

[rangerpimpn84]

cool i just wanted to make that clear. u cant tell em nodda. wel i feel the same way so o well right. well i dont have time for lil things i got a sway bar , head and turbo to find

The simple fact about air filters is that they are able to flow a total amount of air. The K&N unit will definatly outflow the factory filter (this is their proof to sell). But this doesn't mean it will produce more power. Why? Well, the engine only draws so much air. The 2.3L we speak of will pull about 152 cfm at 5000rpm. (140ci / 2 X 5000rpm X 75%ve / 1728) The factory filter has a max flow that exceeds the 152cfm the engine requires. How do I know, well the factory set up is adequate for the 4.0L which requires roughly 248cfm with a lesser 70% ve. Lets give the K&N filter the advantage (yes, sarcasm) of a max flow of 1,000,0000 cfm.

Now for everything to make sense! The 2.3L draws about 152cfm as mentioned earlier. So, it takes 152cfm for the little guy to produce 100hp. The factory filter flows (this is a guess based on the 4.0L figure) 248cfm. The factory filter allows the engine to make its total 100hp while drawing 152cfm while having the ability to flow an additional 96cfm. The K&N unit will allow the engine to make 100hp while drawing 152cfm. The K&N will have the ability to flow an additional 999,848cfm. But wait, the engine can only inhale 152cfm! So what does this mean!? Well, the engine has made no more and no less power than before. If you did something to increase the amount of air the 2.3L requires (TURBO!!!) then yes, a high flow filter would benefit. But for a stock engine, it puts you in the "I wasted my money" group where you can mingle with all the turbonator guys.

I think you explained it right there (i have a K&N but it was there when i bought the truck so eh lol

an engine is no more than a fancy air pump, the more air you can make it suck in, and the more exhaust you can blow out. the more power you make. there is testing that proves k&n filters filter more air due to a larger media in the filter.

The only testing that says there is a HP increase is K&N's marketing BS, nothing else!! The reason they will flow more air is due to holes in the filter media, not because there is more filter media!

woww r we still arguing this fact. this thread is like 3 weeks old

If someone can put a cold air intake on there truck and "feel" a difference only because it's in their mindset that there will be one, Then couldn't someone NOT feel a difference due to the fact that they think the cold air intake won't work? Without a dyno, It's all just power or suggestion.
But on a different note, A cold air intake wouldn't hurt, as long as you retain all the sensors. And just think about it: The stock air intake is pretty ridiculus. It goes from the top rear of the engine, almost to the front of the engine compartment, back to the airbox halfway down the fender, then down like four inches and back up to the radiator support. That's like 4 feet for the incoming air to travel! Not to mention that the intake is all different sizes and makes a bunch of sharp bends. Now if you put on say a 2 foot long intake tube with smooth bends, not only does the air move more easily, but you can get more air into the engine faster. And if that intake tube's chrome oreven aluminum, it will reflect heat unlike the heat-absorbing black plastic of the stock intake. So the incoming air is cooler. Not to mention the fact that the intake tube wont go from big to small to big etc. That's why on the older vehicles with round air filters people put "open" filters instead of the stock one that runs to the inner fender. Even, though the air is warmer, the engine can get more air faster so you get better performance anyways. In the ranger's case, you can get both of best worlds because imo the stock intake is horrific.

well said.

I think this proves without a doubt, that there is way more filter media area in the OEM paper filter:


I thought it would be interesting to do a comparison of the K&N drop in air filter vs the OEM paper air filter:

Filter media comparison:

Summary: K&N filter media area = 270 SQ. " OEM Paper media area = 1485 SQ. "

wow u ruined a $50 filter and your time to point that out. thanku ranger bro for that. that was well said thanx.

 

[Bryan22]

Bob is going to fight K&N until they send a hit man after him! lol.

 

[rangerpimpn84]

i guess so. well ive never had oil on my maf or in my intake so that might b youre truck or an over oiling issue. but whatever the case b were all intitled to our opinions.

 

[skyy_4life]

thats correct. we are all entitles to our opinions.

Welcome.

I'll tell you what I did..everyone has their own ideas though. I have a 1993 2.3. From factory you essentially have a cold air intake. But they put restrictions on it to make them run quiet. You also have alot of componets running into and out of your factory air intake that are there for a reason. So this is what I did....

Take off the intake tube between your throttle body and air box. Inside of that tube will be a cone insert. Remove it. Can be done by hand or persuaded with a pliers. Put the tube back on. Change out your OE filter with a K and N (some people don't like to use them but thats up to you.)
I did notice a difference when I did this mod and it only costs you a 50 dollar filter. You will also get the cold air intake sound with that baffle removed from the tube. I also freed up my exhaust quite a bit and noticed a big difference compared to everything that was stock. Anything helps when you only have 98HP to work with.

Good luck!

Honestly if your not in the mood to go with an intake and want to keep stock parts do this I did it today, along with the zip tie mod on the Throttle cable , it put a smile on my face I'll tell ya that.

I have a B2500 and purchased a K&N cold air intake kit and it had no improvement but pinged like crazy (which the 2.5 does fairly easily anyway) I took it off because I couldn't stand the constant pinging just driving down the street.
