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

The +0.25mm sizing indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined undersize during an engine rebuild to ensure proper clearance.

What is Manganx strengthening?

Manganx is a material additive used by King Engine Bearings to strengthen their aluminum bi-metal bearings. This helps to improve the bearing's durability and resistance to wear under demanding engine conditions.

Are these bearings compatible with all Audi A4 models?

These bearings are compatible with Audi A4 models from 2002 through 2009. It's always recommended to verify your specific vehicle's engine code and year range against the full fitment list.
