Re: 2016 High Altitude Cold Air Intake

Ha ha ha for 2016, Chrysler engineers figured out the old Subaru trick of inverting the intake manifold. I mean WTF were they thinking in the first place to create that idiotically long intake tube connecting the air filter box to the manifold, curve it and giving it a few large baffles. Sure, it may help with noise but not with efficiency.

Maybe an intake manifold swap is a viable mod ???

I will follow up with the answer about the engineers. Those who designed the intake for 2011 (i.e. 2011-2015 model years) have now been tasked with designing the coolant reservoir. Because it is always better to have it made of opaque black plastic so you could run dry, and never have any idea of where the coolant level is..

Re: 2016 High Altitude Cold Air Intake

According to some of the info that's out there CAI do not increase HP anyway , better to do a catback system for a better sound

The level can be checked by looking at the side of the reservoir.

Re: 2016 High Altitude Cold Air Intake

I just put an aFe CAI on my KL TH 2016 3.2L Pentastar.

I like the design much better as it goes into and bolts into the bottom half of the stick air box so it actually has access to the cooler air.

I've usedK&N filters and looked at MOPAR and KN CAI when I had my 2011 WK2 3.6L V6, but like many CAI they suck air from the middle of the engine bay. I guess that bears stuff for Hinda CRV which are near the exhaust and tranny but those were best served by just having a good filter.

CAI do sound great though. Can't deny that.

Everyone should remember the following. Air, fuel, spark and compression are the four things you need to make an engine run. If you increase air flow, you need to increase fuel to keep the desired lambse (desired air/fuel ratio) the processor is demanding. Your stk. processor has the ability to adjust fueling both ways (leaner and richer) but there is a limit of how much it can adjust.

In the video he states the engine will only take in some amount of air flow because that is the way it was designed. That statement is true but if the air induction system is restrictive then it's not taking in the maximum amount of air flow because of the restriction in the stk. air box. If your air induction system is restrictive, any modification to the air inlet system that removes this restriction will result in more air at WOT.

His view on OEM: The OEM does not design your vehicle for maximum performance, I'm hoping we can all agree on this. OEM Engineers are looking for a relationship of excellent drivability, clean emissions, longevity and horsepower. Increasing one of these areas will result in a decrease in another area, depending on how radical your modifications are for a stk. engine.

His view on Mass Air: A Mass Air Meter measures air mass. Increasing the diameter of the tubing will throw off the calculation for the Mass air meter but in most cases the aftermarket will keep the tubing the same diameter on their CAI system. If they don't then you bought crap and drivability and WOT will suffer. But Jeeps are Speed Density vehicles so no Mass Air Meter to worry about.

His view on cold air: The stk. air box is basically a cold air setup and the aftermarket loves buzz words, so they use the term cold air because colder air is more dense and has the potential to make more power. He states in the video the aftermarket cold air system is drawing in hot air. Air in our engine bay is moving, it's not at rest. At WOT, air is moving extremely fast so it doesn't have enough time to pickup a lot of heat from the aluminum tubing. So I don't agree with hs view on cold air.

Most Aftermarket parts are crap, because they are cheap copies of properly designed aftermarket parts. In most cases you get what you pay for.

I hope this helps

Re: 2016 High Altitude Cold Air Intake

In order to determine if something is a restriction, you need to test it . There have been numerous testing done on CAI kits, some show a HP gain while others do not.......why.

Either the stk. Air box wasn't a restriction or the aftermarket CAI kit is crap. It's that simple.

Thanks

Re: 2016 High Altitude Cold Air Intake

The Floridian doesn't discuss different fuel blends which can very state to state because if seasonal requirements. He also doesn't talk about OEM Ram air induction system on normal aspirated engines that so many different companies have used over the years be they located on top of the hood or as air dam that pushed maximum flow in behest he the grill.

When you have a properly designed system that locate the intake filter at the same part of the car that the OEM has cooler air coming in, and they build it with heat sheik ding on the area surrounding the air box and using materials coating the intake piping. With the amount if air coming in, it will cool any residual heat except in very hot climates.

Again, even the better design offer just a small bump in bhp and torque on the dyno, but like different spark plugs, with broader, hotter sparks, their use is debatable, but insignificant in most cases. The goal is complete combustion with all the fuel mixture burnt with the by-products of combustion being CO2 and water vapor with as little CO and unburnt fuel as possible. Of course the manufactures engineers can't get it perfect, due to costs and reality, which is why Cat converters have been required as well as other anti-smog gear that has become more year after year, especially in large and populated states like CA.

I think he isn't very knowledgable about combustion and took the education, probably provided by the manufacturers and went with the company lines. It's easy to parrot back what you are told in the basics of science. If he could easily explain the use of platinum and palladium as catalysts, in combustion in the CAT converter, then maybe I could take the guy who completely forgot what he was talking about a bit more seriously.

Oh that and that F1 and Indy Cars all use some type of Ram Air design as well. If it didn't help at all or hurt power, then you wouldn't ever see it in racing.

Re: 2016 High Altitude Cold Air Intake

Another point to remember is you should compare apples to apples. Meaning, compare CAI systems from a Jeep and not another vehicle. The CAI system on the Nissan in the video is a bad design and probably lost HP on that vehicle. A properly designed CAI as mentioned above with a heat shield around the filter, located in the same area of where cooler air is drawn in will perform best. With that said, does a CAI kit for a Jeep increase HP by huge amounts? No it doesn't but it does increase HP and TQ to the rear wheels but gains in those two areas will be small. Is it worth it, that's for the owner to decide.
