How to Install a Modquad Air Filter Kit

The need for speed exists off-road as well as on the track. Upgrading ATV air intakes by adding a larger intake tube or high-flow air filter will increase throttle response. By increasing the amount of air the off-road engine has available, a performance air intake will deliver more horsepower than restrictive factory air boxes and filter units. Little effort is needed to install a Modquad air filter kit that includes a reusable, high-flow air filter. You only need some shop tools and 20 minutes to bolt on extra horsepower and added throttle response from an off-road vehicle equipped with the upgraded air flow of a Modquad ATV air filter kit.

Difficulty: Easy

Instructions

Things You'll Need:

• ATV Modquad filter kit Spray cleaner (brake/carb) Silicon gasket gel Utility knife (razor) Screwdriver Wrench Rag

1. Park the ATV in a sunny, level spot to work in. The tools you need will be only a screwdriver and crescent wrench. The Modquad air filter kit comes with a new filter base and neck and filter. The clamps used to secure the filter to the mounting neck are with the kit, and all the parts inside the kit should be defect-free. Remove the parts from the box and be sure that the instructions confirm that you have all the parts.

2. Remove the factory air box that connects to the intake manifold. The existing air filter will be removed as well as the filter housing, and mounting bracket that connects the air intake outlet to the filter housing. The old air box and filter should be recycled, and the fasteners retained in a cup. Place a plug over the opening to the air intake after the factory air box has been removed to avoid debris from falling into the intake and combustion chambers during the Modquad air filter kit installation.

3. Clean the face of the air intake. Use brake or carburetor cleaner and a utility knife to remove any built up gasket material, dirt or oil that may have been left behind around the intake opening. The new mounting bracket for the Modquad filter kit requires that these surfaces be like new prior to installation to get the best results. Take the time to clean the junctions of all upgraded parts to get the best results from any investment in off-road performance.

4. Remove the rag or plug that is covering the air intake inlet of the engine. Secure the Modquad mounting spacer onto the ATV air intake inlet. Use new or existing fasteners to create the best seal. Add silicon gel as an additive to make a thin silicon gasket in between the intake surface and the air filter spacer.

5. Attach the high-flow air filter to the mounting spacer or neck. The filter is secured using the hose clamp provided with the kit. Drive the screw so the clamp tightens around the filter neck and the mounting space together. Inspect the installation for loose fasteners or obstruction. Cover the filter with a dust bag to add extra protection from dirt and flying clouds of material that help to clog factory air filters.

Tips & Warnings

• Lightly oil surfaces where flexible and metal parts meet. Protect the seal with a light covering of motor oil will keep the moving parts from drying out over time. Purchase a filter cleaning and oiling kit when you buy a performance filter system. Be prepared.
• Dirt can enter an engine through the air intake, causing damage. Remember to always use a clean air filter protected from excessive dirt. Tap out and away from the filter elements any built up dirt after riding where an exposed filter unit is present.
