RFX Pro Engine Distribution Plug Set (Blue) — Ref. FXEP4020099BU
Designed for demanding quad and motocross riders, these RFX Pro series distribution plugs combine lightweight construction with precision. Machined from 7075-T6 aluminum, they offer superior dimensional stability against heat and pressure stresses encountered around the engine casing. CNC machining ensures tight tolerances and a more reliable fit than standard plastic plugs, which are often prone to breakage.
The plugs feature a convenient hex head (8 mm and 6 mm) for quick installation and removal with a wrench, and accept OEM O-rings to ensure a proper seal. Their hollow design minimizes weight without sacrificing strength, and the blue anodization protects the part while adding a racing aesthetic touch.
Main Features:
Easy Installation: remove the old plug, retrieve the original O-ring, clean the threads, replace and tighten with the appropriate hex wrench.
Compatibility (examples): YAMAHA WR 250 F, YZ 450 F, YFZ 450 2WD.
