The addition of an aftermarket exhaust, a cold air intake, air filters, and of course a supercharger are just a few of the additional elements that contribute to increased horsepower. The biggest gain in power will undoubtedly come from the supercharger.

What change does TRD cold air intake make?

On my 2017 trd pro, I installed the trd cai. It actually had an impact. If you want to spend the money, I advise you to do it. compared to takeoff and low-speed acceleration, an improvement.

Which cold air intake should I pick?

The most crucial factor to take into account is proper application, just as with any other aftermarket component. Consider the following five aspects before choosing one for your car:

1. Design specific to a vehicle. Most cold air intake manufacturers create them to meet specific engine and vehicle types, years, makes, and models. You must first make sure that the product you are acquiring and installing is advised for your particular car.

2. Substance. The second thing to think about is the substance. As was said before, the goal of a cold air intake is to eliminate heat buildup so that colder air may enter your engine. As a result, be sure to pick one constructed of materials that can withstand heat.

3. A style of cold air intake. The design or kind of the cold air intake system is the next thing to consider. There are typically two: the real cold air intake system and the short ram system.

  • Short ram system: In essence, the short ram makes it simpler to access the air filter. Its design typically necessitates less fabrication or plumbing work.
  • A real cold air intake places a strong emphasis on advancing the air filter as far as feasible. Compared to the short ram design, it generates more additional cold air flow.

4. The flow of the intake tube. Since a straight line is the most effective way to get from point A to point B, it’s vital to take the tubing’s flow into account as well. This idea has a significant impact on cold air intake systems. The air flows more effectively via straight pipes than through ones that are slightly bent.

5. Water defense. It’s also crucial to buy an aftermarket cold air intake with lots of water and wet weather protection. The last thing you want is for any water to be drawn into the cold air intake because this could result in severe engine failure issues.

The best source for information on cold air intake systems is actually a performance specialist for your particular car model. Find technicians who specialize in your particular car type online, and ask them for their advice on the best aftermarket cold air intake.

Is an open or closed cold air intake preferable?

When compared to its open airbox sibling, the closed cold air intake is more powerful. Whether you’re at the track or on your preferred winding backroad, it can always maintain intake air temps as low as possible when running very hard.

Does inhaling cold air boost mpg?

If cold air intakes generate cooler air than your car’s original intake, fuel economy may rise by 3 to 5 MPG. Depending on the component and your automobile, this might improve your MPG.

If you replace an old air intake, you risk losing performance and fuel economy if the new intake is weaker than the old one. You can possibly be pondering whether or not a new intake will significantly increase MPG.

If the intake is more powerful than the factory air intake, you should expect an improvement of no less than three and no more than five miles per gallon.

A Stage 2 cold air intake is what?


Expert Reaction:

The filter and the box it is mounted in will be replaced by a stage 1 cold air intake. All of that is replaced by a stage 2 system, like # AR300-237, which also has extra equipment, typically a hose or collar with a greater diameter. The air flow is better the higher the stage number. For your 2012 Ram 2500, I’ve included a link to the cold air intake options.

TRD exhaust: Does it increase horsepower?

TRD exhausts offer an outstanding combination of increased horsepower and a deep, throaty growl. They are built from 409 anodized stainless steel to help prevent corrosion. Denser, cooler, oxygen-rich air is an advantage of adding a TRD Performance Air Intake System to an engine.


By moving the engine air filter outside of the engine compartment in an effort to inhale colder air, the main advantage of cold air intake is that it increases power. In addition to being out of the engine compartment, it is frequently positioned low to the ground. There are two benefits to this. First off, because heat rises, it prevents hot air from the engine compartment, the brakes, or any other heated component from ascending. Additionally, this filter arrangement aims to draw in the densest air possible because colder air is more dense and denser air is lower. The more fuel that can be burned and the more power that can be produced for improved engine performance, the denser the air must be.


It is true that the cold air inlet usually receives denser air than the stock intake. However, it is frequently more expensive because it is longer and requires more complicated routing.

The installation process becomes more challenging and time-consuming as a result of the increased complexity.

The cold air intake system’s biggest strength can also be its biggest drawback. More specifically, it’s because of where the filter is located.

To draw in colder, denser air, a low-profile filter outside the engine bay is ideal. However, there is also a lot of dampness and trash in that area. No matter how advantageous it might be, it won’t matter if your intake contains a lot of water. Your car’s engine may hydrolock and suffer irreparable harm if it ingests a substantial amount of water.

Is it worth it to invest in a cold air intake?

The short answer is yes to the question of whether a cold air intake system is eventually worthwhile. The advantages are still there and actively assisting in making your car function more efficiently, even if you aren’t aware of them.

What functions do a TRD air intake?

TRD Performance Air Intakes, in short, can boost the performance of your engine, as shown by the fact that they produce more torque, horsepower, and efficiency than factory equipment does.

What issues might a cold air intake bring about?

The Check Engine Light coming on, a decrease in power, acceleration, and fuel efficiency, as well as an abnormally high idle, are common symptoms.

Do you require a cold air intake tune-up?

If fitted and maintained correctly, a cold air intake that doesn’t require tuning won’t harm your engine. With cold air intakes that require a tune, you must be more cautious.

Larger tube diameters are used in intakes that require tuning to boost airflow to the engine. The car’s intake tube is designed to only let a specific volume of air into the engine from the manufacturer. The mass airflow sensor (MAF) measures the air mass as it passes past it and transmits that information to the car’s computer. The amount of fuel injected into the engine is then decided by the computer. You need a method of telling the car’s computer if the intake tube’s diameter changes. Thus, a tune is necessary.

The MAF (Mass Air Flow) sensor won’t change the air-fuel mixture to handle the additional airflow without tweaking the ECU. Running lean is defined as having too much air and not enough fuel. There is a risk of serious engine damage when your air-fuel ratio is off. Your CAI shouldn’t harm your engine if you install and adjust it correctly.
