The aftermarket companies have already addressed the issue with most intakes by putting heat/water shields designed specifically for keeping water out on the 13-14s. Soo... Yes!

 

So really any brand i go with I'll be good?

 

You have a CAI right from the factory. You'll be hard pressed to improve on it.

 

Well i eventually want to run a Bama Cam Tune. Purchasing and o/r h pipe aswell. I was told you need and o/r pipe and a cai for the Bama Cam tune?

Off road mid pipe yes, CAI no.

 

Oh sweet, i won't bother with the cai then, thank you!

 

Yay, another member doesn't drink the Kool-Aid. You just saved yourself several hundred bucks and disappointment when you find out your no-tune CAI made you point-nothing faster at the dragstrip.

 

So glad someone else agrees with me. Yeah CAI are pretty but useless. The cold air induction we have on our 5.0's is going to be the best for our cars. I did buy a k&n drop in filter, just for better air flow.

 

A good CAI with a tune will make little more HP that a stock CAI with a tune. They are mostly for looks and sound. (a sucking sound) If you're not going to tune, forget it.

 

Yeah, I bought mine because I didn't want to buy the Boss manifold adapter and I really like the look of a blacked out Steeda cai.

But if I had a '13-'14 with the vented hood, I wouldn't buy a cai. I know, they remedied a fix for it, I saw the YouTube video but I still wouldn't want to chance it. A mouse could climb in there and poop on it.

 

What people don't get is unless you significantly alter the airflow demands (VE) of the engine, it doesn't matter what intake is on there. Adding more airflow doesn't mean the engine will demand more. It's not the 1980s any more with 5.0 litres of engine sucking through a convoluted 100 mm snorkel in the fender. Strangely enough, I've heard but not verified the intake pipe feeding the 5.0 is actually a hair smaller dimensionally than the one feeding the 4.6 in 2010. That should hint at what I am talking about.

Plus, people don't get that the type of airflow into the engine is just as important, if not more so, than the volume of airflow. A modern engine is VERY dependent on the MAF transfer values being correct, in real time. The quickest way to screw this up is the have turbulent, disrupted airflow past the MAF sensor. This can actually go as far as nuking your engine if it's screwed up bad enough. On older cars, it'd just make it run rough and get lousy mileage.

 

So getting a hood with "functional" vents on a 11+ isn't resulting much gains or advantage?? I always have some haters or old school ppl who don't know anything about modern cars talking crap about my "fake" hood scoop

 

It's all for looks! The gains (if any) are so minimal. I love the way the 13-14 hoods look, but is a pain with an after market CAI. There are plugs that "help" keep the water from reaching the CAI.

Nope...you might see a gain over 160 mph...

 

Most people haven't the slightest clue how aerodynamics works anyway.

Most hood scoops, (even if connected to the intake) do nothing anyway, as they are too close to the car's surface and the surface friction creates a boundary layer of slow moving air so, at best, it might be characterized as a kind-of CAI.

What's actually best is for the engine to draw air from a non-moving pocket of relatively stable, unheated air. This is why lots of cars use the inner front fender well. There is cooler, more stable air here than underhood. Our cars draw from behind the grille fog and, while not perfect, it's at least outside the engine bay and reasonably far away from the rad.

Hood vents can serve a secondary purpose besides letting out heat. They can reduce underhood air pressure and that can affect the amount of front end lift at high speeds. Lots of race cars use these, particularly high speed endurance racers like Le Mans cars. It has to be designed-in, though, it won't happen by accident, most likely.

 

Well i learned alot from this haha. I wont waste my money then on the cai. I'll buy the tuner instead

 

Just remember a tune will void warranty... I would stretch its legs a bit, give it at least 5-10K to make sure u have a good car w/o major drivetrain issues

 

Ohhh alright. I should wait to get rid of the cats then obviously too.

 

Yeah. A cat remove will require a tune for best performance as you'll freak out engine management at times and throw a light for sure if they aren't there. This ain't no '79 5.0.

Definitely run it in some...says the guy who put Procal on his car at 3421 kilometers... These cars do loosen up some and the oil consumption stabilizes. Watch that dipstick for the first few thousand ks.

 

I think a CAI does well when you complete the entire exhaust system and upgrade it fully. A CAI alone will do nothing. Get a CAI and tune it, does more. Get headers and off road x pipe, more power gains. One can suck all the air into the engine but the factory manifolds and cats will only let you push out the air so fast. The key to making more HP is sucking more air into the engine, shove that air in and push that air out as fast and as much as possible. One can't do this with the restrictive manifolds and cats on. The CAI is just one more ingredient in making your car faster and increased HP and torque. It's like baking a cake. Milk alone will not make a cake. Milk, sugar , flour , eggs , etc when combined is when the cake becomes more to its final stage. Same for modding your car. Each mod is just one ingredient to completing the cake.

 

Well said

 

Well thanks for everyone's help I was going to run LTs but i have emissions testing here so i decided not to. My repair shop i work at does the testing so i would pass it either way but i wont bother haha. I'll wait until i hit 5k or so and keep checking the oil.

 

What does Long Tube headers have to do with emissions and not passing. I never head such? I'm familiar with the issue of an off road x pipe not passing emissions but that's it. The long tube emissions here thing, I'm confused about.

 

LT eliminate the cats that are right off the factory shorties; there's yer problem, right there....

Here's some advice from 30+ years of f*cking stuff up: Decide what you want to accomplish, what your budget is and then select parts that will achieve your goal without busting the budget.

personally, I committed to maximizing what I have on the cheap and you can see the results in my sig.

When you buy long tubes to replace the factory shorty manifolds , you have to buy one of two things. 1, off road x pipe which will cause emission issues. 2, buy a high flowing catted x pipe. Catted x pipe has cats and not an emission issue. The emission issue has nothing to to with long tubes. One just needs to buy the high flowing catted x pipe that fits onto the long tubes. hope that helped!

 

It's not quite as totally simple as that, depending on your jurisdiction and the severity of enforcement of your emissions regs.

Some will demand no changes from stock, period. Some will allow what is indicated above and some have no laws at all.

It is a federal offense to tamper with any emissions control equipment and some shops are rightfully concerned with this. An individual faces little legal risk but a company faces more. Adding a catted X or H also may not allow your car to pass a sniffer, if that's done where you are because those cats will behave differently than stock, being a lot further downstream than factory.

Well Sir, I'm certainly not an emissions expect by any means and you could be correct. Its been my understanding that a high flowing catted x pipe is completely legal because the cats are not being removed. I have never heard of anyone with catted x pipes not being able to pass an emissions test but I guess anything is possible but never heard anyone on hear say that. Lol

 

Guy who i work with just installed LTs with catted x pipe and it throws his light on every once and a while. His is an 06 so I'm not sure if that has something to do with it?

 

I also think there was one in Texas but that I'm not sure on

If it was me, I would find that guy that will pass it as long as you leave a $50 bill in the exhaust

 

I also think there was one in Texas but that I'm not sure on

Not saying there is but wonder if there is more to the story on why they failed emissions other than just having headers and high flowing catted x pipe.

 

Get yo Lil 3.7 outta the 5.0 forums lmao jk we get off topic sooooo easy these days

 

Were easily distracted. Lmao. I'm gonna buy the new bolt on 1.3 liter mod to make mine an instant 5.0. Ba ha ha ha ha

 

On the emissions testing here they plug into the OBD 2 port and they check under the car for your cats if there are no cats they will select it and you will fail. I've noticed alot of cars that dont have them are running cleaner.

 

Where is here? Lol I'm not trying to be a dick but we don't know where you live.

 

Sorry about that and Connecticut

 

That's in the city too correct?

 

Bristol Connecticut is where I'm at

The guy here also had a tune for emissions and he still passed when his car was tuned. He had an o/r x pipe before he switched to a catted.

 

CAI

I had the same questions about CAI as other people on here. (I got a new '14 GT as well). I was ready to drop some $ on an aftermarket one, until I took another look under my hood to realize they come with a CAI. So doing some additional research took me here, where you all confirm that it comes with one and not to waste $ if your not going to re-tune it. (which i don't plan on at the moment)

So thank you all for the knowledge! I can now go find an exhaust I want...
