Questions about this item

Should I choose this rear main gasket set over other Fel-Pro sets for my engine?

What does the transparent colour mean once the gasket is installed in the engine?

The transparent colour identifies the material visually; it does not change sealing performance once the gasket is seated in the rear main cap.

What interface or standard does this gasket set follow, and what does that limit?

The set follows the original equipment specification for the listed application, limiting use to engines that match the BS40158 part number.
