The air filter holder replaces the standard cover and makes a lot more air available to the engine, which is noticeable in the increase in torque, especially in low and medium revs. By subjective comparison with the original, there is no increase in noise, only a slightly deeper sound.
Due to the shape and design of the intake silencer in combination with the original underbody cover, it is impossible that the engine (e.g. in heavy rain) could suck water into the combustion chamber.
Purely Czech production (including purchase of materials from Czech suppliers) with emphasis on quality.
Sold in two variants:
– for the original Royal-Enfield paper filter,
– for cotton and polyester air filters,
includes a measurement report from the engine brake.
The air filter holders are of our own development!
We have developed holders that do nothing to restrict the air flow to the engine intake and ensure the filter is properly pressed against the intake silencer, eliminating the possibility of false (unfiltered) air being drawn in. The difference is especially noticeable in the increase in torque and flattening of the power curve.
