ICT Billet DFM DOD Delete Plug Kits
ICT Billet DFM DOD delete plug kits contain performance parts for newer GM Gen 5 L84/L87 5.3L/6.2L engines (2019+). They eliminate the factory Dynamic Fuel Management (DFM) system by plugging the oil passages in the engine block.

What it does: * Blocks oil passages: The kit contains aerospace-grade billet aluminum plugs (and hardware) that physically seal the holes in the engine block where the DFM solenoids once were * Replaces DFM/DOD: It allows you to convert from DFM (and the older DOD/AFM systems) to a standard lifter and camshaft setup, eliminating potential failures and improving reliability * Improves performance: By ensuring all cylinders are always active, it restores smooth throttle response and consistent power * Required when using a DOD camshaft to plug the bores in the engine block under the valley cover * Compatible with L84 and L87 engines only * Compatible with Gen V, LT series engines Key components: * 8 billet aluminum plugs * 16 O-rings, 8 clamps and bolts for installation When you need it: * When installing a performance camshaft * To fix or prevent DFM/DOD system failure. * To optimize performance and reliability on L84/L87 engines
