Mitsubishi Eclipse Air Intake Systems
Since its introduction to the market in 1990, the Mitsubishi Eclipse was considered a model sport coupe among enthusiasts. This vehicle comfortably seats four passengers and features a 2.4-liter, four-cylinder engine that generates 162 horsepower. Upgrading to one of the cold air intake systems from manufacturers like AWM, Injen, and K&N may improve the fuel economy of your Eclipse Coupe, no matter the model year.How does the air intake system work?
Air intake systems are one of the most basic elements that make combustion engines possible. For an engine to fire up, it requires the right ratio of air to fuel. The air intake draws air from outside the engine through a tube and directs it into the cylinders to cause combustion. Impurities are removed from the air by allowing it to pass through an air filter first. There are three types of air intake systems:
- Stock air intake - These factory-installed intakes are notable for their convolutions that are meant to suppress the sound of the engine and their use of paper filters.
- Cold air intake - Cold air intake systems have a longer air duct and fewer bends that allow cooler air to enter the piston chambers than a factory air intake. This enables the motor to generate less heat and improves fuel consumption.
- Short ram intake - This type of intake is meant for sportier high-performance vehicle models like the Mitsubishi Eclipse Spyder. It is characterized by shorter, wider pipes that use larger amounts of heated air to increase combustion efficiency.
Upgrading your Mitsubishi to a cold air intake allows your car to use less fuel to fire it, meaning more horsepower and greater fuel economy. Aftermarket air intake systems manufactured by Injen and other companies known for Mitsubishi upgrades usually also offer your Eclipse Coupe or Spyder more efficient filtration through materials like screens or cotton gauze as opposed to paper. This improved filtration results in cleaner burning as well as fewer clogs and less frequent air intake systems and engine maintenance for Eclipse owners.How do you install a cold air intake system?
Installation is as simple as removing your factory air intake from your Mitsubishi Eclipse and replacing it with the new cold air intake; the whole process usually takes less than two hours and requires only basic hand tools and mechanical ability. The tools you'll need include the following: Phillips and flathead screwdrivers, air intake upgrade kit, adjustable pliers.
- Park your Mitsubishi on a flat surface, engage the parking brake, and pop the hood.
- Loosen the bolts on the air intake cover and remove it.
- Remove the air filter from its housing.
- Loosen the intake tube clamp, and disconnect the electrical sensors by squeezing the clamps.
- If your Eclipse has a mass inflow sensor in the tube, now is the time to remove it.
- Loosen the clamps on the tube, and remove it from the motor.
- Remove the air filter housing.
- Install the new housing and other cold air intake components from the kit in the reverse order; make sure that the air flow meter is installed so the arrow is pointing in the direction of the air flow.
- Take your Mitsubishi for a test drive to make sure the installation was successful.
