Honda HA4 Air filter (Round)
$23.00
This OEM round air filter fits the Honda HA4's factory airbox exactly. It traps dust and grit before they reach the engine, protecting internal components from premature wear. A clogged filter hurts throttle response and fuel economy. Replace it regularly — it's the cheapest engine insurance there is.
