This is a special made RedNeck that was custom made for the HPI Baja 5B 5T. It replaces the stock outer stage filter found on your car. Now you will have 3 stages of protection with the famous RedNeck pre-filter added to the inside single stage your car already has. Keeps dangerous dirt, sand, dust and mud out of your engine.
All serious off-readers will agree that there is no better protection than an oiled foam filter. Users must use foam filter oil for proper results (not included). Users must always test for proper movements of throttle linkage after installation. Some trimming on the outside of the filter may be required.
