Short Ram Air Intake for Honda Monkey (2019-2021) OHC Engine

Wake Up the 125cc Horizontal Single: Short Ram Intake for 2019-2021 Honda Monkey

Who Is This For? Designed specifically for Honda Monkey owners running the 125cc OHC engine who want to unlock the bike’s true personality through improved throttle response and a deeper, more aggressive engine note during daily urban riding or weekend cruises.

The Airbox Bottleneck: From the factory, your Monkey is choked by a bulky, restrictive plastic airbox designed for maximum silence rather than maximum flow. When you crack the throttle to keep up with traffic, the 125cc Horizontal Single feels sluggish, struggling to pull through the mid-range because it simply cannot breathe. This restriction masks the engine’s potential and leaves the exhaust note sounding more like a vacuum cleaner than a classic mini-moto.

The Engineering Solution: We engineered this Short Ram Intake to delete the restrictive factory baffles and replace them with a mandrel-bent T304 aluminum intake tube. By providing a direct, high-velocity path for oxygen to reach the manifold, this kit eliminates the "laggy" feeling found in the stock setup. Crucially, this design includes a precision-built IAT sensor mount and crankcase breather nipple, ensuring your ECU receives accurate data without the "Check Engine" lights common with inferior universal filters.

The Comparative Edge: Why This Beats the Competition

• The Performance Gain: Delivers a noticeable boost in horsepower and torque by up to 10%, allowing the 125cc engine to climb the RPM range faster.
• Premium T304 Construction: Unlike cheap plastic or thin-walled generic kits that heat-soak and crack, our T304 aluminum piping is lightweight and durable enough to handle the vibrations of a single-cylinder engine.
• Correct Sensor Integration: Unlike generic pod filters that require "zip-tie" solutions for your sensors, this kit features built-in mounts for the stock IAT sensor and breather hose to maintain factory-level reliability.
