The TopDog V parallel flow oil bypass filtration system can be fitted in school buses that use a spin-on, full flow filter. As a vehicle is driven, oil flowing into the system is diverted to the bypass filter, cleaned and routed into the engine galleries. TopDog V facilitates a better-running engine, improved fuel economy, extended oil and filter service levels, and lower emissions.
