Clip (09401-16403) by Suzuki

A cracked vent hose, a tired valve or a missing clip in the emissions system can bring on fuel smell, a rough idle or a poor running engine. The Suzuki KingQuad 400 Clip (part number 09401-16403) is the genuine Suzuki replacement. It is one of the factory parts Suzuki uses to route air, fuel vapor and emissions plumbing on your ATV, so the system works the way it was designed.

Witchdoctors carries Suzuki EVAP and emissions parts for ATVs. Check the fitment, options and tips below, and contact our team with any questions before you order.

Why Choose Suzuki

Suzuki says its Genuine Parts are the same parts used to build every Suzuki product, and each one is designed for a specific product and model. According to Suzuki, these parts are tested for performance, quality, durability, safety and comfort. Suzuki also introduced the world’s first four-wheel ATV, and it still builds the KingQuad and QuadSport lines today.

Suzuki sometimes supersedes part numbers. If the number on your old part is different, or your model isn't listed, contact our team before you order.

How the Emissions System Works on Your Quad

Suzuki ATVs use a set of small parts to manage fuel vapor and exhaust emissions. Suzuki says the current KingQuad 400ASi uses a Pulsed-secondary AIR-injection (PAIR) system and a catalyst-equipped exhaust to help it meet EPA standards. Valves, hoses, gaskets, clips and brackets all have to seal and stay in place for that system to work.

When one piece cracks or goes missing, the rest of the system can't do its job. Replacing the worn part with the same Suzuki part number puts it back to factory condition.

Signs It's Time to Replace

Look for cracked or hardened rubber, split hoses, loose clips, burnt gasket surfaces and valves that stick. A strong fuel smell after riding, popping on deceleration or an idle that won't settle can also point to a leak somewhere in the emissions plumbing. Inspect the whole circuit while you're in there; small parts in this system tend to age together.

Buying Guide

• Part number: Match 09401-16403 to the number on your old part or your Suzuki parts diagram.
• Fitment: Confirm your year and model in the fitment tool; this part is listed for 2014–2026 models.
• Check the routing: Take a photo of how hoses and clips are routed before you remove anything.
• Replace in sets: If one clip or gasket is brittle, the matching ones nearby are usually close behind.

Installation

Most emissions parts are reached by removing body panels or the seat. Work on a cold engine, keep track of hose routing and clamp positions, and replace any gasket you disturb. Follow the Suzuki service manual or the manufacturer's instructions for your model.

Before You Install

Let the engine and exhaust cool completely. Have the Suzuki service manual for your model on hand and follow its steps and torque values.

Care and Maintenance

Inspect emissions hoses and clips when you service the air filter. Keep the area free of mud packing, which holds moisture against rubber and metal parts.
