Cold Air Intake Suggestions

I know, not really any hp gains. Want to buy a CAI for the sound since the 5.7 is way too quiet. Anyways, as far as sound or dyno supported power gains go, which is the best to buy? Volant? K&N? Thanks

I went Mopar for an OEM look. Very high quality, looks great and gives a nice sonic improvement combined with my Magnaflows.

Think i've already decided on corsa catback for exhaust, just need a CAI to pair up with it now.

I've got the volant Intake and it sounds fantastic. Additionally, there are several dyno tests on YouTube on the wk2 hemi showing the volant is one of the only intakes that increases power on the hemi.

Did you get the traditional style or the box/enclosed version?

Volant makes probably the best dry filter but one can spin a lot of tales with a dyno. Its so easy to fool the naive, I used to demonstrate that now and then in a previous life .

You are going to get zero gain unless you also tune, and then the CAI contribution is in the noise. Depending on the model year, tuning can be difficult/expensive.

A less effective filter, like the K&N heavily marketed, will allow more noise to escape, but then you will likely be dealing with dirty throttle bodies and valve/ring wear down the line.

The Volant CAI with dry filter is a good filter.

Plan is Corsa cat back and tune eventually. Hearing lots of good things regarding the Volant intakes

Whats cold about these filters? They seem to pull the air from inside the engine bay, the factory one pulls air from the outside under the hood lip, isn't that going to be cooler?

CAI is a hold over term that relates to a free flow intake. The advantage of these so called CAIs is they do away with the intake resonator. But, as you guess, the OEM intake brings in cold air, and is tuned for torque and mid range power at the expense of a little off the top end, its very good. If you always drive more than 4000 rpm, however, a aftermarket CAI may provide noticeably better power, if you always drive less than 2000 rpm, your performance may be hurt. It averages out to not make much performance difference for most folks. Style and sound are subjective.

I used to drive a 95 Ford F-250 with a 460cid 7.5L 240 HP and I made the mistake of putting a K&N Filter in it, I also put one in my wife's 92 B150 Ram Van with a 318cid 5.2 L (318 cid) V8 147 HP. I believed their advertising more HP more Gas Mileage,it's BS! (that's my thoughts) Had more problems than they were worth. I took the K&N Filter off my Ford P/U and it seemed to have twice the power it had without the oil bath filter. So when we took it to our mechanic (my wife Van) he said to get rid of it. So stay away from the K&N Filters. If Chrysler Corp thought they were goo they would still be using them.
As for a CAI system I'm at a loss but I am looking to o OEM from Mopar.

I spent about 20 years modifying/racing cars, from 1000whp evos to 1500rwhp trucks, i CAI can help this engines for the simple reason to remove all the resonators on the oem intake pipe. Each on those traps make a lot of turbulence inside the throttle body. Getting a one direction flow is something to try(im talking about small numbers, real power well is a different story) . At least thats what i saw all this years on the hemi engines. For me AFE power has nice products and there is a dry filter intake with closed air box. Im waiting mine for my 3.6. I just installed the replacement filter and the difference is noticeable in mpg. Power is not.

After all the great things I heard about Volant combined with their current $60 rebate I ordered one with the powercore filter. I'll let ya'll know how it works out

Yes, lets establish some real world expectations. (I have 50+ years experience but who's counting)…

Over the years, the performance capability has been talked about here by smarter people than me. Its easy to make make the common mistake of mixing apples with oranges and coming up with a grapefruit Years of racing cars and modified engines doesn't translate well to a WK2... unless you have tons of money and are into highly modifying it (and willing to deal with a non street legal vehicle). Not saying its not fun. Those ads are misleading marketing BS. I don’t buy K&N because you can’t trust their marketing. Once in awhile a marketer will get into the forum and try to sell some product

You can certainly do things like pulling out seats to save weight, and chase a few HP in a narrow rpm range by throwing wild cams in, headers. Throwing the RIPP supercharger on provides measurable performance gains, and is a hoot.

These WK2s have narrower exhaust manifolds and milder cam profiles than other Hemi MOPARS, along with the adaptive ECU. The V6s exhaust manifold is in the head itself. Unlike 20 years ago, the factory has done a good job tuning intake/exhaust flow, they had to spend the development money to meet EPA restrictions. The WK2 Hemi can benefit from just a little more aggressive cam profile, however.

You may initially notice some performance difference after installing a CAI, but the ECU will adapt it out over a hundred miles or so. As mentioned, the WK2 has a highly efficient intake from the factory with tuned resonators to improve low and mid range drivability. It is not constrained by airflow restrictions as you may think and CAI manufactures want you to think.

Early model WK2 did not have a locked down ECU, so it was a bit easier to squeeze some performance out by tuning. Newer ECUs are locked down, so you spend more money to replace it with a tuned one. So, in the end, spending money on a CAI for WK2 performance is throwing money into the wind. I saw maybe a 1 HP gain at high 5000s rpms, but a drop of 2 at the lower rpms typically used on the street, in a quick test. The torque hit is more dramatic, and torque is important for the street. These small numbers are in the noise, however. There are production variances, so if you happen to have a WK2 that does not run well, a CAI could help a bit. Now on the interweb you will find other vehicles that for one reason or another seem to be noticeably improved. Of course, if its on the interweb, it must be right

Sage advice by old timers here is that the most effective method to improve street performance and driver satisfaction is to shift manually, use a more appropriate rpm/gear ratio for your diving style. Takes a little effort, but its cheap and legal. By far most of a tuners's improvement to driver satifaction is the modification to shift points.

Nothing wrong with buying a CAI for sound or style or driving satisfaction, but that should be your WK2 expectation. The sound influences your butt dyno, and one typically drives in a better rpm range. It doesn’t hurt performance much, but that depends on your driving style.
