Hello, I am thinking about putting in a K&N filter, has anyone done this and had any luck?
I have to side with dusty on this one.....changing out the filter housing isn't going to do much. Plus K&N or anything else that requires oiling is just a bad idea...even though there's already oil in the engine lol. If anything....if you're not going for the Mopar RAM intake ...I would maybe swap out your filter for a dryflow AEM or something similar, maybe remove the carbon filter if you do. Honestly...anything else that's costing you $300-500 is better spent not on the intake but on something else.Hello, I am thinking about putting in a K&N filter, has anyone done this and had any luck?
Agree 100%.I'm sure this will be heresy to some.
The air filter for engines used today is designed as an integral part of the fuel delivery system. Changing the resistance to air flow will effect the delivery of fuel at various rpm points thereby altering the factory fuel mapping. How this affects engine performance can vary depending on the engine and the design of the factory induction system. There's testimony from various sources that it improves vehicle performance, and other testimony that it does not. There's at least one video of a dyno test on a Mustang where a less restrictive air filter actually reduced horsepower.
Since today's truck motors are designed to bring in power at lower rpms, a low restrictive air filter probably won't provide much if any benefit at road speeds.
Whether a low restriction air filter provides any performance benefit aside, the ability to filter out small particles is highly questionable. Much of the filtering is dependent on the viscous oil used to coat the filter. Progressively over time this oil dissipates away thereby reducing the filtering capability.
I've used these filters on my ATVs, and frankly found them to be a PITA. They've caused performance issues and increased maintenance time.

Technically there isn't a MAF in the new Rams but the concept is the same. If anything...a highflow filter can give a better throttle response at best but that's where the benefits stop unless you have a high flow exhaust and an engine tune to complement all of it.... Even then...you're talking about $1500 - $2500 spent for what? Maybe +10 HP/Torque gain? Nothing you'd notice in a Ram lolAs I understand it, the Mass Airflow Sensor‘s job is to make adjustments to the air flow to keep a consistent flow of air going into the fuel inj system. So unless you make adjustments to the programming, the MAF will simply adjust itself to the preprogrammed volume of air feeding the injectors regardless of a freer or restricted air filter.
Actually, a Mass Air Flow sensor does not control the flow of air into an engine, but feeds a signal voltage to the Engine Control Module which determines the amount of fuel delivered to each cylinder based on the amount of air that flows across the sensor.As I understand it, the Mass Airflow Sensor‘s job is to make adjustments to the air flow to keep a consistent flow of air going into the fuel inj system.

"the MAF will simply adjust itself to the preprogrammed volume of air feeding the injectors regardless of a freer or restricted air filter."
True to an extent. The fuel control systems used in automotive service are not truly linear, but a large series of mapped set points that engineering has plotted during testing. As originally plotted (or programmed) the fuel delivery is based on a known amount of air flow resistance in the factory system. At low air flow rates (amount of air rushing into the engine) any difference in resistance will probably not be detected by the engine computer. As air flow increases, the resistance of the air delivery system (air or filter box, ducting, etc.) has more of an effect on fuel control.
The best example of this effect is at wide open throttle (WOT). At WOT most systems expect to see, and will compensate for, the factory designed resistance. If this resistance is removed or drastically reduced, the fuel map internal to the ECM may not be able to provide the correct air-fuel mixture.

Did not know there isn’t a MAF on these (obviously ). Thanks for that bit of new info PowerJrod!Technically there isn't a MAF in the new Rams but the concept is the same.
