Short Ram Air Intake for Honda GROM SF (2013-2020)

Wake Up Your JC75 Engine: High-Flow Short Ram Intake for Honda Grom SF

Who It’s For: Engineered for 2013-2020 Honda Grom and MSX125 owners running the JC61 and JC75 powerplants who are tired of the stock sluggishness and restrictive intake acoustics.

The Symptom: The factory airbox on the 125cc horizontal single is designed for absolute silence, not performance. It utilizes a massive, heavy plastic enclosure and a convoluted air path that forces the engine to work harder just to breathe, especially in the higher RPM range. This results in a "lazy" throttle response and a noticeable lack of torque when you’re trying to pull through the gears or keep up with traffic on the open road.

The Engineering Fix: This short ram system replaces the bulky OEM airbox with a streamlined, mandrel-bent intake tube that significantly reduces fluid drag. By creating a shorter, straighter path for oxygen to reach the throttle body, we increase air velocity and reduce pumping losses. The inclusion of a genuine K&N washable filter ensures maximum surface area for filtration without the bottleneck of a paper element, giving your JC75 engine the ability to respond instantly to throttle inputs.

Why Mechanics Choose This Kit

• Optimized Air Velocity: By removing the factory baffles, we improve the engine’s volumetric efficiency, resulting in more consistent torque throughout the mid-range.
• Deeper Induction Growl: Swapping the plastic box for a high-flow setup provides a throaty, aggressive intake sound that reflects the true nature of the 125cc engine.
• Sensor Integrity: Unlike "universal" kits, this includes a built-in IAT (Intake Air Temperature) sensor mount and a dedicated crankcase breather nipple, ensuring the ECU maintains proper fuel trims without throwing a check engine light.
