Cold air intake worth it ?

A good alternative is removing the OEM charcoal filter at the top of the box (you can cut out the plastic rivets, be careful not the drop any debris in the process). That alone will free up the intake, though switching to an aftermarket performance drop-in filter could be a benefit, at the least saving money on future air filter changes.

Just like almost all CAI, removing that charcoal filter is just a placebo effect and doesn't change anything with airflow or performance

Here is a decent test for different filter's ability to filter dirt.

Race engines are built to take advantage of increased airflow and they are more concerned about airflow than filtering ability because they have no expectation that their race engine will race over 100,000 miles before they rebuild it.

There is no way that charcoal filter isn't causing an airflow restriction, just physics.

Now, if you are saying that restriction is taken into account by the air flow mixture and tuning of the engine, absolutely that makes sense.

That being said, my main reason to remove it is I'm afraid over time it will slowly disintegrate, pieces getting inside and damaging the engine. Besides, the charcoal filtration was depleted years ago, the fact it isn't replaceable is a joke if it was meant for emissions.

The factory Mopar intake removes it anyways, it doesn't need to be there even for CARB/EPA reasons. I say remove it before it becomes a problem. Instead of removing in place, highly recommend you remove the top of your box (disconnect from intake tube), cut out the filter, clean any potential debris before reinstalling.

Just saying in the context of airflow and CAI not making any difference, telling someone to remove the charcoal filter is in the same context. It literally does nothing to helpm

I really wish Ram's Airflow intake had been designed to look more like the Vararam, which is so classic Mopar looking!

If you remove the plastic cover, the Mopar intake looks pretty cool, and quite similar to the Vararam

Absolutely. I mentioned removing the charcoal filter around performance, and honestly unless you dynoed it, how do you really know one way or the other? Does anyone have performance figures around removing the charcoal filter and installing a K&N? Literally does nothing, or does something but not worth it?

But I re-centered my comment to mention it's a worthless, possibly damaging thing to leave in your airbox, that people should consider removing it, certainly after several years of being completely exhausted and possible a thread of coming apart and entering the engine.

I did think about leaving it off when I was checking/cleaning it.
I assumed I'd be sucking hot air, since it wouldn't be sealed like the Vararam, so didn't do it.
I'd be interested to hear if it would sound different with the lid off when mashing the throttle! I'd think it should.
