An aftermarket air intake or cold air intake system is a performance upgrade made to a vehicle's engine that replaces the factory-installed air intake system. Its primary purpose is to improve the engine's performance by enhancing airflow into the engine, which can lead to increased horsepower and torque. Here is a breakdown of what it does and its components:

Function of an Aftermarket Air Intake System

·         Improved Airflow: Aftermarket performance parts such as these are designed to allow more air to enter the engine compared to factory intakes. This increased airflow can help the engine breathe better, especially under heavy acceleration.

·         Enhanced Engine Performance: By improving airflow, these systems can increase the engine's efficiency and performance, potentially resulting in higher horsepower and torque.

·         Better Engine Sound: Many aftermarket air intakes produce a more aggressive and pleasing engine sound, which can enhance the driving experience.

·         Potential Fuel Efficiency: In some cases, improved airflow can lead to better fuel efficiency, although this depends on driving habits and the specific vehicle.

Components of an Aftermarket Air Intake System

·         Air Filter: Often made from high-flow materials, these filters are designed to trap dirt and debris while allowing maximum airflow. They can be reusable and washable, which is an advantage over disposable filters.

·         Intake Tube: The tube connects the air filter to the engine's intake manifold. Aftermarket intake tubes are typically larger in diameter and smoother in design to minimise airflow restrictions.

·         Heat Shield: Some systems include a heat shield that helps to protect the intake air from engine heat, which can reduce the temperature of the incoming air and improve performance.

·         Mass Air Flow (MAF) Sensor Adapter: This component ensures that the MAF sensor fits properly within the new system, allowing the engine control unit (ECU) to measure the correct amount of air entering the engine.

·         Mounting Hardware: Various brackets, clamps, and screws are included to securely mount the intake system to the engine.

·         Air Scoop (optional): Some systems include an air scoop to draw in cooler air from outside the engine bay, further enhancing performance.

Considerations to keep in mind

·         Installation: Aftermarket air intake systems often require some technical skill to install, though many are designed for straightforward, bolt-on installation.

·         Legal and Warranty Issues: Depending on local emissions regulations, some aftermarket systems may not be street legal. Additionally, they can sometimes void vehicle warranties, so it is important to check with manufacturers.

An aftermarket air intake system can be a popular modification for car enthusiasts looking to enhance their vehicle's performance and sound.

Debunking some myths about aftermarket air intake systems

There are several myths and misconceptions about aftermarket air intake systems. Here is a breakdown of some common myths and the truths behind them:

·         Myth: Aftermarket Air Intakes Will Always Improve Horsepower

Truth: While many aftermarket air intake systems are designed to increase horsepower by improving airflow, the actual gains can vary significantly based on the vehicle and the specific intake system used. Some cars may see substantial improvements, while others may show minimal or no difference. Factors like engine tuning, exhaust system, and overall vehicle condition also play a crucial role.

·         Myth: Aftermarket Intakes Void Warranties

Truth: While it is true that modifying your vehicle can potentially affect the warranty, the Magnuson-Moss Warranty Act in the U.S. protects consumers by requiring manufacturers to prove that a modification directly caused the damage before denying warranty claims. However, it is wise to check the specific warranty terms of your vehicle and consult with the dealership if you are concerned.

·         Myth: All Aftermarket Air Filters Are Better Than Stock Filters

Truth: Not all aftermarket filters outperform stock filters. While some high-flow filters can improve airflow, they may not always filter out particles as effectively as stock filters. The effectiveness can depend on the quality of the material and design, so it is important to research specific products before making a purchase.

·         Myth: Aftermarket Air Intakes Increase Fuel Consumption

Truth: In some cases, aftermarket air intakes can actually improve fuel efficiency by allowing the engine to breathe better, especially if combined with other performance upgrades and proper tuning. However, if a driver changes their driving habits due to the increased power (such as more aggressive acceleration), fuel consumption may increase as a result.

·         Myth: They Cause Engine Damage

Truth: If installed correctly and designed for the specific vehicle, aftermarket air intakes should not cause engine damage. However, poorly designed systems or improper installations can lead to issues like increased engine temperatures or unfiltered debris entering the engine, which can be harmful. It is important to choose reputable brands and follow installation instructions carefully.

·         Myth: Aftermarket Intakes Require Frequent Maintenance

Truth: Maintenance requirements can vary by system. Some high-flow filters are reusable and washable, while others may require periodic replacement. In general, they may not require significantly more maintenance than stock filters, especially if they are properly designed.

·         Myth: Aftermarket Air Intakes Are Only for Performance Cars

Truth: While many enthusiasts install aftermarket intakes on performance cars, they can also benefit daily drivers. Improved airflow can lead to a more responsive engine, better throttle response, and even minor improvements in fuel efficiency, making them appealing to a wide range of drivers.

·         Myth: You Can’t Use Aftermarket Intakes with OEM Components

Truth: Many aftermarket intakes are designed to work alongside stock components. They can be part of a comprehensive upgrade strategy, allowing users to enhance performance without completely replacing the entire intake system.

When considering an aftermarket air intake system, it is essential to do thorough research, understand the specific benefits and limitations, and choose a product that aligns with your vehicle's needs. This can help you avoid misconceptions and make informed decisions about your modifications.
