CSC O-Ringless Dummy Plug Set – 6.0L Powerstroke | 4-Pack
Eliminate one of the most common high-pressure oil system failure points on the 6.0L Powerstroke.
This kit includes 4 CSC O-Ringless Dummy Plugs, designed to replace the factory-style dummy plugs and eliminate the O-rings that can fail, leak, and cause hard starts or hot no-start conditions.
What’s Included
- 4 CSC O-Ringless Dummy Plugs
- Loctite 680
The factory 6.0L Powerstroke dummy plugs rely on O-rings to seal the high-pressure oil system. Over time, those O-rings can deteriorate, leak, and contribute to problems such as long crank times, hot no-starts, and loss of high-pressure oil.
CSC’s O-Ringless Dummy Plugs eliminate the O-ring sealing point completely.
Each plug is CNC-machined from 316 stainless steel and designed as a permanent upgrade for the factory-style dummy plug.
This 4-pack is ideal for customers who specifically need four dummy plugs without purchasing upper standpipes.
