GMC Sierra 2 Engine VIN Character 2004, Grid Heater Delete by Longhorn Fab Shop®. The Longhorn Fab Shop® Grid Heater Delete Plate for the LBZ and LMM Duramax is a WIN WIN! At high boost levels there can be over 2 PSI of pressure drop across this restrictive grid heater. A 2 PSI pressure drop means that your engine is seeing 2 PSI less boost than the engine is producing resulting in lower Horsepower (HP) and torque number, higher EGTs, and slow spool times. Contrary to popular belief the grid heater IS NOT necessary for cold weather start up.
Fitment notes: Fits Models Manufactured after May.
- Made utilizing the finest grade materials
- Exceptional quality at a competitive price
- Will serve you for many years to come
