What does the '+0.25mm' size mean for these bearings?

The '+0.25mm' indicates that these bearings are 0.25mm undersize. This means they are designed to fit crankshaft journals that have been machined down by 0.25mm during an engine rebuild. This ensures proper oil clearance and lubrication.

What is the construction of these connecting rod bearings?

These bearings utilize a bimetal construction, which features an aluminum base. This type of construction is known for its good heat transfer properties and durability in engine applications.

Are these bearings a direct replacement for stock?

These bearings are a direct replacement for the specified Mazda E3 and E5 engines, but they are sized 0.25mm undersize. This means they are intended for use after the crankshaft has been machined to match this size during an engine rebuild.
