Product Description

Michigan Motorsports AFM / DOD Oil Block Off Plug Set – Gen IV LS & Gen V LT

Fits 2005–2018 Gen IV & 2014+ Gen V – Set of 8 Oil Galley Plugs

This AFM/DOD Oil Block Off Plug Set includes eight (8) precision plugs designed to block the oil passages in 2005–2018 Gen IV and 2014-current Gen V engines equipped with Active Fuel Management (AFM) / Displacement on Demand (DOD). These plugs are installed beneath the factory VLOM plate and are commonly used when converting from DOD/AFM lifters to traditional LS or LS7-style lifters.

The plugs install by lightly tapping them into the oil galley passages until they sit flush with the bottom lip of the bore. Each plug is internally threaded (4mm x .7) to allow for easy removal if service is ever required. This is a simple, effective solution when retaining the original DOD/AFM valley cover while converting the valvetrain.

Key Features & Benefits

Complete Set of 8 Plugs: Includes eight oil galley block-off plugs required to properly seal AFM/DOD oil passages under the factory VLOM plate.
AFM/DOD Conversion Ready: Commonly used when replacing DOD/AFM lifters with conventional LS or LS7-style lifters.
Flush Install Design: Designed to be lightly tapped into place and installed flush with the bottom lip of the oil galley bore.
Serviceable Removal Threads: Internal 4mm x .7 threads allow easy removal if future service or teardown is required.
Designed for OEM Valley Cover Use: Engineered specifically for use with the original DOD/AFM valley cover configuration.

Important Fitment Note

These plugs are for use only with the original DOD/AFM valley cover. They will not fit or function properly with non-DOD valley covers or DOD conversion valley covers.
