Noise comes from air turbulence, which is not good! The other problem with the larger diameter intake tube is the
velocity of the air will decrease, which will screw up the MAF sensor measurements. With the CAF standards, all
vehicle manufacturers put a lot of engineering into making the engines as efficient as possibe, which the intake
is part of. Congratulations, you have successfully screwed up your intake!

we drive rangers....not hondas... NO 5hp for youzzzzz bro.

just accept the fact that what JP is saying is right.

if you cant take the slightest critisim....then dont post.

Normally the fuel trim kam table will correct for this. Doesn't make it "ok" but it does somewhat fix it bar 3 major fails:

1- fuel trims don't trim in open loop - that's bad for high load/high rpm parts of the base map

2 - you lose headroom in your kam tables - kind of like buying a house with a shower that you have to turn it most of the way to "hot" everytime just to get to the temperature that you like to take a bath in.

3 - turbulence in the maf will cause major major problems at high rpm/high load. I've replaced a few broken parts on turbo engines that died like that - how did I know? I logged maf and knock during the failure. OEMs work harder than you think to get laminar flow at all parts of the load vs rpm part of the kam tables.

hey man, free words from a guy who builds and owns high horse power cars and does it for a living is hard to pass up. when he is rattling off all the stuff that we even could begin to dream to know, you may want to listen. i think he has a point. a valid point at that. its best to take it with a grain of salt and move on. this forrum is a really good place to tap resourse's and learn. your still fairly new on here and havnt even seen the demons that can come out and play. go read the "torsion bar" thread. you will see what i am saying. go check out JP7's projects...see were he is coming from. look before you leap man

ok, in newby english lol. on our trucks (and most vehicles) cold air intake will not add power. even if the products says 5hp increase. its not the case. it doesnt atually get cold air. there is no air being pushed through the intake itself, its simply breathing in warm air from the engine compartment generated from the engines heat.

as for the better noise it makes, its called air turbulance. and it means just that. you are hearing the air become turbulant as it goes through the intake.

honestly the best part of adding a kit is the fact that the emements are cleanable and usually last the life of a vehicle. the cai is a very moot mod and almost pointless.

Okay, but i like the painted tube other than a ugly black one. that was the point from the beginning not power nothing just a better cleaner look. that is all. and it saved 300 dollars than buying a k&n so im happy

As for mods for power what would you add a supercharger yes, but besides that anything else?

a supercharger will net 5hp

rofl as far as bolt on power my bet would be underdrive pulleys.
I removed the air silencer on the stock intake and it actually felt like i got a little power out of it but it also sounds louder too. So i created more air turbulence but i gained power? also put a drop in K&N filter yesterday, hoping for a little more fuel economy. ( needed a new air filter any way so why not?)

The K&N filters like garbage, they will either a) let a lot of small contaminants in, b) screw with your MAF sensor, or c) both.

I removed the air intake silencer on my ranger and it made it louder, that was it. Go dyno the thing before and after, I bet you gain nothing, or possibly even lose some power. The "silencer" is a venturi, and I'm better it is no random happening.


As for the original poster's intake, it is pulling hot air which is less dense. I don't know that the MAF tables are messed up, since the MAF sensor is a complete enclosed unit. However I have never actually tuned anything so anything I say about it is mostly theory.
My f150 has a speed density sensor or something like that for a MAF sensor, it is a little wafer that slides into the intake tube. A bigger intake tube on with the same MAF scaling will screw up the readings so it has to be tuned.

As much as I generally bash cold air intakes, I have one in my F150. lol
I'm not entirely sure why though. It is an AEM brute force cold air intake with a washable dry filter. I got it almost new for $80, and I needed to have my truck tuned anyway. I figured I would give it a shot. Air intake temps are slightly higher around town as expected, even with a heat shield. On the highway they are pretty similar to the stock airbox, with enough air flowing around. I tuned the truck at the same time, so I'm sure that all of the increased performance was from the tuning. I would be surprised to see an increase from the intake itself, but maybe at high RPM. It does seem to pull harder over 4,000 but this tune was written by a different person than the last which could account for variances. The intake does sound good, but in the end that is probably all it is good for.

Because now you are getting the same amount of air, plus dirt and oil that will contaminate your MAF sensor.....I think
these are good reasons NOT to use the K&N......

for a good power boost. a custom tune will be your best bet. maybe under drive pullys too

I got my K&N stock airbox replacement in my 04 Ranger for free (Perks of the job I have) - It cleans the air just fine: it just does not make the truck any faster.

I also got the K&N cone filter on my Car for free: I had to make an intake that would mate up my huge HTA3582R compressor inlet - It makes a difference over 400whp because this is where the stock intake is restrictive on my IX. I am over 600whp now. A little different situation than most of the guys around here.

well i got the K&N because now i wont have to buy another filter because i can just keep cleaning this one and my old one was disgusting! but i was talking about the difference in power when i took the air silencer off and still used the old filter.
