How Cold Air Intakes Work
As it’s been said many times before, your car (just like you) has to breathe in order to function. All of the air
that is sucked into the engine passes through the air intake, goes through the throttle body into the intake manifold, and finally
the cylinders themselves. Once it reaches the cylinders, fuel is mixed with the air (given it’s not a carburated
engine where this occurs before the manifold) and everything is ignited, producing power.
Without air, specifically the oxygen within the air, no power could be generated. Conversely, the more air in the
engine, the more possible power. In fact, maximizing the engine’s air intake is the whole operating principle of
turbo and superchargers. This is where a cold air intake comes into play.
Colder air is more oxygen dense than warm air. So a cold air intake’s job is to keep cooler air going into the
as opposed to the hot air that can build up in the engine bay. There are a variety of ways that a cold air
can achieve colder air. A common method is moving the air intake a bit farther from the engine itself or
the air intake with a heat shield. Additionally, certain materials themselves can resist heat, like various
and the holy grail of automotive aftermarket parts, carbon fiber.
Cold Air Intakes For Your Mustang
A common question we get from customers is the difference between an intake that states it requires a tune and an
intake that doesn’t require a tune. Then, there are even some Mustang cold air intakes out there that have
removable spacer that will allow the owner to choose. The basic explanation is that the computer on a factory
can only comprehend so much air registering through the mass air flow (MAF) sensor in the intake tube. If you
to alter that air-flow too much, the engine could run lean and ultimately cause catastrophic engine failure. So,
choosing the correct intake for your needs is vital to your Mustang engine’s longevity -- read on to
out the difference!
What Makes A Cold Air Intake “Tune-Required”
"power increases throughout the entire powerband"
The main difference between a “tune-required” intake is the diameter of the intake tube. This is
the computer is told from the factory that the intake tube is a certain diameter and if that diameter is
the engine could to lean, idle incorrectly and ultimately cause serious problems.
That’s why some cold air intakes, like the Roush Intake for the
2015-2017 GT, included an 85mm spacer to allow Mustang owners to use the factory tune with their intake.
This 85mm spacer will allow the Mustang’s computer on a factory tune to operate correctly with the added
benefits of a freer-flowing filter with some power gains.
However, if you were to remove the 85mm spacer to reveal the full 105mm bore, the MAF sensor would be confused on
factory tune since the bore size was changed. If the computer is tuned correctly for this increase in intake
size, then you will be able to see the full benefit of adding a cold air intake to your Mustang. With
computer allowing and recognizing more air through a larger bore, you’ll be able to really see power
throughout the entire powerband -- especially towards the top!
Tune Required Cold Air Intakes

To get the absolute most out of your cold air intake, it’s important to pick up a tuner to finish the combo.
Adding a cold air intake to your engine will definitely free up some power and restriction in the intake track,
a proper tune will allow you to get the most out of your intake. A good example of a tune-required intake would
most JLT Performance intakes.
Ideally, if you're adding an intake to your Mustang, you'll want to pick up a tuner to go along with it. It's
adding a supercharger to your Mustang but keeping the factory all-season tires on the rear. What's the use of
600+ horsepower if you can't put it to the ground and spin all the way through 4th gear? The same kind of
goes along with a cold air intake -- if you want to get the most out of your new intake, a tune to go along with
modification is what you need to finish the job properly!
Benefits of a Tune-Required Cold Air Intake:
- A tune will allow you to get maximum power from your new cold air intake.
- No question of whether or not your engine is running too lean.
- Louder Intake Noise
- Increased Gas Mileage
- Better Throttle Response when combined with a tune
No-Tune Required Cold Air Intakes

The benefits of a cold air intake are awesome - more intake noise, added power, increased gas mileage -
almost a no-brainer! If you don’t want to get a tune in order to maximize the power increases of your cold
intake, there are still many reasons to rid of that factory airbox.
Adding a no-tune required cold air intake, such as most Airaid Intakes, you’ll still be able to
increased power, increase gas mileage and the intake noise we all know and love. These numbers won’t be as
drastically different than an intake/tune combo but definitely worth it.
A large reason as to why many would go with a no tune required cold air intake is the fact that you don’t
to mess with your Mustang’s computer. For those that want to keep the factory tune intact on their Mustang
want a step up in power - a no tune required intake is the perfect choice for you!
Benefits of a No Tune Required Intake:
- Slight Increase In Power
- Louder Intake Noise
- Increased Gas Mileage
- Don’t Have To Tune - For those who are more concerned with the factory warranty
How To Install A Cold Air Intake
Cold air intakes usually can just be bolted onto the engine bay. Although there are a variety of ways that cold
intakes can be hooked up into the engine bay, the majority of them can be installed in a simple plug and play
manner. This is another big reason why cold air intakes are such a popular mod. In case you want to see how
this is yourself before taking the plunge, then check out this video from our video team that shows how easy it
Making The Choice
If you’re the kind of Mustang owner who wants to get every ounce of power as they can out of their ride,
cold air intake and tune combo would be ideal for you. The tune will allow you to get every horsepower possible
of adding the intake to your car. It’s a win-win.
Now, if you’re just looking for a bump in power on your street car but aren’t too worried about
every horsepower out of it, then a no tune required intake is for you. An added benefit of choosing this kind of
intake is that you won’t have to tune your car which keeps your factory tune intact - this is very
to some Mustang owners.
