Installing an AMSOIL Bypass Oil Filtration System is a fairly simple process that can be done right in the comfort of your own garage; no professional installation is required. AMSOIL provides bypass systems specifically designed for some of the more popular applications. If you don’t see your specific application, you may still install a bypass system on your vehicle. Depending on the space available in your vehicle, choose either the Universal Single-Remote Bypass System (BMK21) or the Universal Dual-Remote Bypass System (BMK23). Follow the purchasing information on the universal system webpage to ensure you receive the right system and components for your application. Once you have determined the right system, refer to the installation instructions and examples.

Installation Example

AMSOIL Bypass Oil Filtration Systems are a valuable asset to prolonging the life of your engine. They are also fairly easy to install, only requiring tools that you would find in a common garage. Bypass systems can be installed on many applications with the same basic installation principles.

Common Mistakes

No installation is fool-proof, and some practices should be avoided because they can be harmful in the long run.

  • Be sure to choose the optimal bypass filter location
    • Make sure the Bypass System is not mounted in harm’s way especially from road debris or off-road travel that could damage the system.
    • Make sure the mounting structure is solid and adequate to carry the weight of the filtration system. Areas with high vibration or moving parts could cause the systems or mounting bracket to break.
    • Make sure the Bypass System and hose is not mounted next to the exhaust. The high temperatures of the exhaust could cause damage to the system and hose.
    • The mount should be located as close to the existing full-flow filter as possible to limit possibilities of leaks or pressure loss.
  • Mount as close to the engine as possible
  • Choose the correct-sized Ea Bypass Filter for the application.
