Why Install an Aftermarket Induction Kit?

Upgrading to an aftermarket induction kit offers several compelling advantages over a factory air intake system. These benefits often include improved horsepower, increased torque, and a more aggressive engine note.

The primary goal of an aftermarket induction kit is to provide a less restrictive path for air to enter your engine. This allows the engine to breathe more freely, which can translate into noticeable gains in acceleration and responsiveness. Many drivers also appreciate the enhanced auditory experience.

Performance Enhancements

Increased Horsepower and Torque: By improving airflow, an aftermarket induction kit can lead to measurable gains in engine output.
Improved Throttle Response: A less restrictive intake often results in a quicker and more direct response when you press the accelerator pedal.
Better Engine Sound: Many aftermarket systems produce a more aggressive and satisfying engine roar, especially under acceleration.

Understanding Your Aftermarket Induction Kit

Before beginning your aftermarket induction kit installation, it is crucial to understand the components involved and the type of kit you have purchased. Most kits fall into two main categories: cold air intakes and short ram intakes.

Types of Aftermarket Induction Kits

Cold Air Intake (CAI): This design typically relocates the air filter away from the engine bay, often into the fender well, to draw in cooler, denser air. Cooler air contains more oxygen, leading to better combustion and more power.
Short Ram Intake (SRI): SRIs feature a shorter intake tube and position the filter within the engine bay. While they provide excellent airflow, they may draw in warmer air than a CAI, potentially offering slightly less power gain but often a louder induction sound.

Common Components of an Induction Kit

Regardless of the type, most aftermarket induction kits include similar core components. Familiarizing yourself with these parts will make the aftermarket induction kit installation process smoother.

Air Filter: A high-flow, often reusable, conical filter designed for maximum airflow and filtration.
Intake Tube: A mandrel-bent tube, usually made from aluminum or plastic, designed to reduce airflow restrictions.
Couplers and Clamps: Silicone couplers and worm-drive clamps are used to connect the intake tube to various engine components.
Mounting Brackets: These secure the induction kit firmly in place, preventing vibrations and ensuring proper fitment.
Vacuum Hoses and Adapters: Necessary for connecting various vacuum lines and sensors from the stock system to the new induction kit.

Tools and Materials Required

A successful aftermarket induction kit installation requires a basic set of hand tools. Gathering these items beforehand will save time and frustration.

Socket Wrench Set (metric and/or standard, depending on your vehicle)
Screwdriver Set (Phillips and flathead)
Pliers (needle-nose and standard)
Torx Bit Set (if applicable to your vehicle)
Gloves (for protection)
Shop Rags or Towels
Penetrating Oil (optional, for stubborn bolts)

Step-by-Step Aftermarket Induction Kit Installation Guide

Follow these steps carefully to ensure a smooth and safe aftermarket induction kit installation. Always refer to your specific kit’s instructions as they may have vehicle-specific details.

1. Preparation and Safety First

Safety is paramount before starting any automotive work. Proper preparation ensures both your well-being and the integrity of your vehicle.

Park on a Level Surface: Ensure your vehicle is on a stable, flat surface.
Engage Parking Brake: Prevent any accidental movement of the vehicle.
Disconnect Battery: Always disconnect the negative (-) terminal of your car’s battery to prevent electrical shorts or accidental airbag deployment. Allow a few minutes for the system to fully discharge.
Cool Down Engine: Ensure the engine is completely cool to avoid burns from hot components.
Read Instructions: Thoroughly review the aftermarket induction kit installation instructions provided by the manufacturer.

2. Removing the Stock Airbox

The first major step in your aftermarket induction kit installation is to carefully remove the existing factory air intake system. This usually involves several connections.

Locate Stock Airbox: Identify the factory air filter housing and its associated components.
Disconnect Sensors: Gently unplug any mass airflow sensor (MAF) or other electrical connectors attached to the airbox or intake tube.
Remove Vacuum Lines: Disconnect any small vacuum hoses or breather lines connected to the stock intake tube.
Loosen Clamps: Use a screwdriver or socket wrench to loosen the clamps securing the intake tube to the throttle body and the airbox.
Unbolt Airbox: Remove any bolts or clips holding the air filter housing in place. Some airboxes may simply pull out of rubber grommets.
Carefully Remove: Once all connections and fasteners are removed, carefully extract the entire stock air intake system from the engine bay. Store these parts safely in case you need to revert to stock.

3. Installing the New Components

With the old system out, you can now begin the aftermarket induction kit installation by fitting the new components.

Transfer Sensors: If your kit requires it, carefully remove the MAF sensor from the stock intake tube and install it into the designated bung on your new aftermarket intake tube. Ensure the O-ring is properly seated.
Attach Couplers: Slide the silicone couplers onto the intake tube and throttle body, but do not tighten the clamps fully yet.
Position Intake Tube: Carefully maneuver the new intake tube into position, connecting it to the throttle body and any other required engine inlets.
Install Mounting Brackets: Attach any provided mounting brackets to secure the intake tube or filter housing. These are crucial for stability during your aftermarket induction kit installation.
Connect Vacuum Lines: Reconnect any vacuum lines or breather hoses to the new intake tube using the provided adapters or fittings.

4. Securing and Connecting

Once all components are in place, it’s time to tighten everything down and make final connections.

Tighten Clamps: Systematically tighten all hose clamps, ensuring a snug fit without overtightening, which can damage the silicone couplers.
Secure Brackets: Ensure all mounting brackets are firmly bolted or clipped in place.
Install Air Filter: Attach the high-flow air filter to the end of the intake tube, securing it with the provided clamp.
Reconnect Sensors: Plug in all electrical connectors, especially the MAF sensor, ensuring they click securely into place.

5. Final Checks

Before starting your engine, perform a thorough inspection to ensure everything is correctly installed and safe.

Double-Check All Connections: Verify that all clamps are tight, all hoses are connected, and all electrical plugs are secure.
