DOD Delete Valley Plugs LS/LT Gen IV / Gen V

Phil’s Swap Shop LS/LT DOD Block-Off Plug Set

Phil’s Swap Shop LS/LT DOD block-off plugs are built for clean, reliable AFM/DOD deletes on modern GM V8s. This kit blocks the factory displacement-on-demand oil feeds in the lifter valley and related passages so you can run a non-DOD cam and lifters. Designed for engine builders and DIY swappers who want a tidy, professional-looking delete that lasts.
