ATV, Side-by-Side & UTV Intake Fuel Systems

Air intake systems for all-terrain vehicles are a key part of the combustion process. The engine requires air to power combustion. Debris from the air gets into the air intake, which could lead to decreased engine performance if the air intake filter, carburetor, and valves are not regularly maintained.

What are the features of the intake system of ATVs?

  • Metal hoses: Metal hoses are stronger and more durable than plastic hoses for the cold air intake. Plastic tends to crack when it is exposed to extreme temperatures, but metal offers resistance to cracking.
  • Ability to customize the layout: The cold air intake system of an all-terrain vehicle can be laid out to your specifications. Different lengths and diameters of hoses are available so you can maximize the performance and efficiency of your equipment.
  • High-efficiency particulate air filter: A high-efficiency particulate air filter removes the tiny contaminants that build up over time. Using a high efficiency particulate air filter allows you to keep dust, soot, pollen, and a wide variety of other particles out of the cold air intake system, which improves fuel economy.

How does the intake system of an ATV work?

The function of the air intake equipment is to provide the engine with fresh air. The three primary parts of the cold air intake for the vehicle's fuel system include the filter, mass flow sensor, and throttle body. A long plastic or metal tube goes from the carburetor's throttle body to the filter assembly. The filter is located near the grille of the vehicle. The cold air intake system increases the engine's power and performance and allows it to run more efficiently. The colder air passes through the filter, which captures most contaminants. Bringing cold air into the engine increases the available oxygen for burning fuel. Bringing in cold air may also increase the all-terrain vehicle's torque, performance, and speed.

How do you clean the intake fuel system of ATVs?

The air intake for the fuel system of an all-terrain vehicle needs to be cleaned of soot, residue, and other debris in order for the ATV's engine to combust fuel properly. Cleaning also boosts the engine's power and performance. To clean the air intake system, be sure to disconnect the battery and keep the vehicle's engine turned off. Remove the intake manifold and either use a pressure washer and biodegradable detergent or use a chemical cleaner to degrease the intake manifold. You will need gloves and eye protection while using any chemical cleaners. Replace the old, dirty air filter with a new air filter. It is also a good idea to flush the EGR cooler and the exhaust manifold while cleaning the carbon buildup from the intake unit. All of the coolant hoses, valves, and hardware should be disconnected, cleaned, and properly lubricated before they are reassembled. You will need Allen wrenches and a screwdriver to disconnect and reassemble all of the hardware and valves.
