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

Wake Up Your JC61 & JC75 Engine: High-Flow Short Ram Intake for Honda Grom OG & 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.

Common Questions

Will this fit my 2014-2020 Honda Grom 125 or international 2013-2020 MSX125?
Yes. This short ram air intake fits 2013-2020 Honda Grom 125 and MSX125 models (both OG JC61 and SF JC75 4-speed 125cc platforms).

Will this intake fit a 2022 or newer 5-speed Honda Grom?
This system is built specifically for the 2013-2020 4-speed Grom (JC61/JC75) and is separate from the 2022+ 5-speed Grom platform.

What is included in the box?
The kit includes (1) washable K&N filter, (1) black aluminum intake tube, (1) fairing rod support, (1) rubber coupler, and (2) stainless clamps.

Does this intake retain the stock IAT sensor and crankcase breather?
Yes. The intake tube features a built-in Intake Air Temperature (IAT) sensor mount and a dedicated crankcase breather nipple to maintain proper factory sensor readings.

Why does the kit include a fairing rod support?
Removing the bulky factory plastic airbox eliminates the stock mounting point for the lower plastics, so the included fairing rod support keeps your body panels braced and secure.
