Bronco 2‑Stage Foam Air Filter for Honda TRX250 Recon / TRX250X / TRX250EX & ATC200X/250SX/250R (1997‑2021)

OVERVIEW

The Bronco 2‑Stage Foam Air Filter serves as a direct maintenance replacement designed to trap fine debris while allowing consistent airflow into your ATV’s engine. Constructed with a dual‑layer foam build and an OEM‑style rubber sealing gasket, this reusable element matches factory dimensions for straightforward installation on Honda TRX250 models.

ENGINEERING & PERFORMANCE

This two‑stage foam air filter traps particulate matter efficiently through its layered open‑cell construction, preventing abrasive dust from reaching critical internal components. The reinforced outer layer sheds larger particles while the inner porous foam captures finer grit, maintaining steady volumetric flow under heavy throttle. Engineered to handle prolonged off‑road operation, the durable polyurethane foam retains its structural integrity across temperature shifts and extended service intervals.

WHY RIDERS CHOOSE THIS

Riders select this two‑stage element because its layered foam structure reliably separates harmful dust from intake air without restricting engine breathing on muddy trails or dusty fire roads. The dual‑layer construction captures fine silica and silt while shedding larger mud clumps, which keeps the intake system clean and reduces the need for frequent swaps. Its direct OEM‑style shape seals tightly against the stock airbox, preventing unfiltered bypass that could damage pistons or cylinders. Built to standard factory tolerances, it fits seamlessly into the existing setup while delivering dependable protection for high‑output four‑stroke engines.
