Dust cover and particulate filter for the Vortex ROK Mini ROK airbox and intake system. This dust cover fits over the intake plenum component of the airbox, to keep dirt, rocks, and large debris out.
Note that this dust cover does not protect the engine or airbox from sand or sand-like debris. In rain or inclement conditions, including going off track, this dust cover is not going to prevent particulates from entering the engine. In these cases, an additional air filter may need to be run. However, also consider that to do so is against the ROK Cup USA regulations, so always consult with your regional technical representatives.
