Can-Am Defender HD8 Intake Valve Kit

The Can-Am Defender HD8 Intake Valve Kit gives 2016–2021 Defender 800 owners a precise, cost‑effective solution for worn or damaged intake valves. If your machine shows hard starts, loss of power, or poor idle caused by leaking intake seats, this targeted kit helps you restore airflow, compression, and consistent performance—without buying extra parts you don’t need.

This Kit Includes:

• (4) Intake Valve

Intake valves control the fresh air‑fuel charge entering the combustion chamber. Over time, heat and mileage can cause the valve faces to pit or the stems to wear. Consequently, sealing suffers and compression drops. By installing new, precisely machined intake valves, you improve seat contact, stabilize combustion, and regain throttle response. In addition, replacing all four at once helps the set bed in evenly for long‑term reliability.

Choose this Intake Valve Kit when inspection shows margin loss, face erosion, or leakage isolated to the intake side. However, if both intakes and exhausts are out of spec, consider our Complete Valve Kit for a full valve‑train refresh. Likewise, if rings or cylinders are worn, pairing this kit with a Top End Refresh or Top End Rebuild can deliver a more comprehensive fix and reduce duplicate labor.

All components meet or exceed OEM specifications for fit and durability. Therefore, professional shops and experienced DIY mechanics can install with confidence. For best results, check guide clearance, verify spring heights, and confirm seat concentricity before final assembly. Finally, complete a leak‑down test to validate sealing and performance gains.
