Product details
RFX Pro Series Engine Timing Plugs are made from 7075-T6 aluminium, which keeps them dimensionally stable when exposed to high heat and pressure. Tighter tolerances from CNC machining help them stay put, unlike standard plastic plugs, which are prone to failure. Built-in 8mm and 6mm hex key heads make fitting easier.
Key features
- 7075-T6 aluminium construction
- CNC machined for tighter tolerances
- 8mm and 6mm hex key heads
- Colour anodised finish
- Lightweight, hollow design
- Takes the OEM O-rings
Fitting instructions
- Take out the old plug. These are normally plastic and are undone using a large flat head key.
- Take the O-ring off the original plug, clean it and fit it to your new plug.
- Clean the threads in the hole, taking care not to let any dirt fall inside.
- Screw in the new plug and tighten it with the correct hex key.
