Spark plug thumb nut set – the shiny brass finish your J40 engine deserves

Make your Austin J40 dummy engine look factory-perfect with this set of four knurled brass thumb nuts.

These are exact copies of the original Champion spark plug top nuts:

• Beautiful polished brass that never rusts

Just pick the right thread when you order, screw them on by hand and instantly the engine bay looks a million dollars.
