Step-by-Step Installation Guide

1. Remove the Factory Air Intake System

The first task is to remove the stock air intake components, including the airbox, tubing, and factory air filter.

  • Locate the factory air intake assembly in your engine bay, typically positioned near the front passenger side.
  • Loosen the hose clamps connecting the intake tube to the throttle body using a flathead screwdriver or socket wrench.
  • Carefully disconnect the mass airflow sensor (MAF) connector by pressing the release tab and pulling the connector gently.
  • Remove any bolts or clips securing the airbox in place with the appropriate socket or screwdriver.
  • Gently lift out the entire airbox and tubing assembly, being cautious not to damage any attached sensors or wiring.
  • Remove the factory air filter from the airbox and set it aside.

2. Clean the Intake Area

Before installing the new cold air intake, it’s essential to clean the surrounding area to ensure optimal performance and prevent debris from entering the engine.

  • Use a clean rag or microfiber cloth to wipe down the throttle body flange and intake port.
  • Remove any accumulated dust, dirt, or oil from the intake path and mounting areas.
  • Inspect the mass airflow sensor and clean it gently with MAF sensor cleaner if needed (do not use harsh chemicals or touch the sensor element directly).

3. Assemble the New Cold Air Intake Components

Your cold air intake kit will come with several components such as the intake tube, air filter, clamps, and sensor adapters. Follow these assembly steps:

  • Attach the provided air filter onto the intake tube’s end, securing it with the supplied clamp. Ensure the filter fits snugly without gaps.
  • If your kit includes a heat shield or airbox enclosure, assemble it according to the manufacturer’s instructions, usually involving bolts or clips.
  • Install any sensor adapters or brackets included to accommodate the mass airflow sensor.

4. Install the Cold Air Intake onto Your Mazda3

With the components assembled, it’s time to install the cold air intake onto your vehicle.

  • Position the intake tube so that its flange aligns with the throttle body.
  • Slide the intake tube onto the throttle body and hand-tighten the clamp to hold it in place.
  • Attach the other end of the intake tube with the air filter positioned to draw air from a cool location, often behind the factory airbox area or within the heat shield enclosure.
  • Secure the air filter clamp firmly but avoid overtightening, which can damage the filter.
