Why Choose K&N for your Himalayan?

The Himalayan 411 and Scram 411 are often subjected to harsh, dusty environments. Stock paper filters can clog quickly in these conditions, leading to a loss of power and poor fuel economy. The RO-4118 maintains high air velocity even when moderately dirty, ensuring your bike stays responsive. Additionally, the slightly deeper intake growl adds a bit more character to the engine's "LS410" thumping sound.
