Michigan Motorsports AFM/DOD Oil Conversion Plug Kit (8-Pack) | Fits Gen IV LS & Gen V LT 2005-2019 | Ideal for AFM Conversions

Upgrade your Gen IV or Gen V LS-based engine with the Michigan Motorsports AFM DOD Oil Conversion Plug Kit (8-Pack)—a must-have when converting from AFM to a traditional performance valvetrain. These precision-machined plugs are engineered to permanently seal off the oil passages behind the valley cover, preventing oil flow to the factory AFM lifters and ensuring a cleaner, more efficient setup for your next build. Each plug features a flush-fit tapered design with a 4mm x 0.7mm threaded center, allowing future removal if needed. Whether you’re doing an LS7 lifter swap, camshaft conversion, or full AFM conversion, this kit gives you a durable, OEM-quality solution designed for long-term performance.
