UTV 4-Stroke Spark Arrestors

Frequently Asked Questions

• What key features should I look for when buying a 4-stroke spark arrestor?

  Prioritize USFS-qualified mesh-type arrestors with mesh openings no larger than 0.023 inches, stainless steel construction, permanent compliance markings, and an exact exhaust outlet diameter match to ensure wildfire prevention, legal compliance, and proper airflow.
• Should I choose a mesh or centrifugal spark arrestor for my ride?

  Mesh/screen arrestors are the preferred, USFS-approved choice for most motorcycles and light UTV use because they’re simple to inspect and clean; centrifugal styles are typically reserved for heavy-duty UTV adaptations that need higher continuous flow.
• How often and how should I maintain a spark arrestor?

  Select a removable, easy-clean design with quick-release clamps and inspect for damage or clogging regularly, cleaning more frequently in dusty or high-use conditions to prevent backpressure and overheating.
• How do terrain and riding conditions affect spark arrestor choice?

  In forested or dry, fire-prone areas choose anti-corrosion, fine-mesh USFS-qualified units with good cleanability, while for heavy continuous use or rough terrain prioritize higher-flow, more durable mesh or compatible centrifugal options.
• What materials and markings indicate a durable, compliant spark arrestor?

  Look for stainless steel construction rated for exhaust heat and permanent manufacturer and compliance markings meeting USFS standards, plus a design that avoids gaps larger than the allowed particle size to maintain safety and legality.
