ETS Replacement Speed Density Air Filter – 3-Inch Inlet for Mitsubishi Evo 8/9 (2003–2006)

Firstly, Buy the ETS Speed Density Filter for 2003–2006 Mitsubishi Evo 8/9. The ETS Speed Density Filter is a replacement air filter for the ETS speed-density intake system fitted to 2003–2006 Mitsubishi Lancer Evolution 8 and Evolution 9 models. It is designed for Evo owners who need to replace an existing filter while keeping their compatible ETS intake setup.

Over time, an air filter can become dirty, damaged, or worn. Replacing it helps maintain proper filtration and supports consistent airflow through the intake system. This replacement filter is a practical option if your current filter needs attention but the rest of your intake assembly remains in good condition.

Before ordering, confirm that your vehicle uses the ETS speed-density intake with a 3-inch filter inlet. This is a filter replacement, not a complete intake kit, so it does not replace the intake pipe, turbo coupler, or other intake components.

ETS Speed Density Filter: Product Overview

The ETS Replacement Speed Density Air Filter is designed for the ETS Evo 8/9 speed-density intake. It provides a straightforward way to refresh the filter without replacing the entire intake assembly.

The filter is listed under part number SP-3606 and is identified as a K&N replacement filter for the ETS Evolution 8/9 3-inch speed-density intake.

Key product details include:

• Product type: Replacement intake air filter
• Brand: ETS-compatible K&N filter
• Inlet size: 3 inches
• Application: ETS speed-density intake system
• Vehicle fitment: 2003–2006 Mitsubishi Lancer Evolution 8/9
• Part number: SP-3606

Check the current product listing and compare the filter with your existing component before purchase. Confirm the inlet diameter and filter design, especially if your Evo has a modified intake or a filter from another manufacturer.

Fitment for Mitsubishi Evo 8 and Evo 9

This replacement filter is listed for the 2003–2006 Mitsubishi Lancer Evolution 8 and Evolution 9 when equipped with the compatible ETS speed-density intake.

However, vehicle model alone does not guarantee fitment. The critical detail is the intake system already installed on your car. Different intake designs may use different filter dimensions, even when they fit the same Evo generation.

Before ordering, check the following:

• Your vehicle is a compatible 2003–2006 Evo 8 or Evo 9.
• Your intake is the ETS speed-density version.
• The existing filter uses a 3-inch inlet.
• The replacement matches the original filter’s connection and overall fit.

If you have an ETS stock-MAF intake, a different turbo-kit intake, or a custom intake pipe, verify compatibility first. Do not assume this filter will fit simply because the car is an Evo 8 or Evo 9.

Benefits of Replacing Your Intake Air Filter

A clean, correctly fitted filter is an important part of a turbocharged engine’s intake system. It helps prevent airborne dirt and debris from entering the intake while allowing air to pass through the filter media.

Firstly, replacement helps maintain filtration. A filter that is heavily contaminated or damaged may no longer perform as intended. Installing the correct replacement helps restore the intended filtration setup.

Secondly, it allows you to retain your existing ETS intake. If the intake pipe, coupler, and other components remain in good condition, replacing only the filter can be a more practical solution than purchasing a complete intake kit.

Thirdly, it supports routine maintenance. Inspecting the filter regularly makes it easier to identify dirt buildup, damage, or a loose connection before these issues become more significant.

A replacement filter does not automatically increase horsepower. Results depend on the condition of the old filter and the overall intake configuration. The main purpose of this product is to replace the existing filter with a compatible component.

Installation and Filter Maintenance

Installing a replacement filter is generally simpler than replacing the entire intake system, provided the new filter matches the existing assembly.

Before installation, switch off the engine and allow the engine bay to cool. Remove the old filter according to the intake manufacturer’s instructions. Inspect the inlet connection and surrounding intake components for damage, loose clamps, or accumulated dirt.

Fit the replacement filter securely and confirm that the connection is properly seated. Avoid forcing the filter onto an incompatible inlet or using an improvised connection. A secure fit helps prevent unfiltered air from entering the intake.

Filter maintenance depends on the filter’s construction and the manufacturer’s recommendations. Follow the supplied care instructions for cleaning, inspection, and replacement. Do not assume that every air filter can be cleaned or serviced in the same way.

If your current filter is damaged, heavily contaminated, or no longer fits securely, replacing it is a sensible maintenance step. Also inspect the intake pipe and coupler so that any other worn components can be addressed at the same time.

If you need a replacement filter for your Mitsubishi Evo 8 or Evo 9, the ETS Speed Density Filter offers a targeted solution for the compatible 3-inch-inlet intake system.

Before placing your order, verify the part number, inlet size, and existing intake configuration. This is especially important if the car has been modified or if a previous owner installed an aftermarket intake system.
