APP’s 6.7L Fuel Rail Plug (sometimes referred to as race plug) replaces the stock pressure relief valve. Why is that so important? It maintains fuel rail pressure under heavy engine load conditions—eliminating changes/decrease of rail pressure.
• Highly recommended for modified engines
• Eliminates low fuel rail pressure DTC code: P1093 and P0087
• For 6.7L Cummins diesel engines
• Machined in the USA from 304 stainless steel (unlike most other lugs which are made of mild steel and then zinc plated)
• Precision quality achieved by using state-of-the art 7 axis CNC lathes.
Fits 6.7L Cummins Dodge Diesel Engines, years 2007.5 to current
Note: Reuse original o-ring from stock plug.
