Cylinder Kit, Biral. 
Restore engine performance while benefiting from enhanced cooling with this OE Match Biral Cylinder Kit. Produced to OE-style specifications, this premium Biral cylinder kit is designed for compatible Porsche applications using the same engine platform where applicable. Featuring cast iron cylinder liners permanently bonded to aluminium cooling fins, the Biral construction combines outstanding wear resistance with superior heat dissipation for improved thermal stability and long engine life. Precision manufactured for accurate fitment and dependable sealing, this kit is ideal for engine rebuilds, maintenance, performance upgrades, and concours-quality restoration projects.

Fits:

The cylinder kit forms the combustion chamber walls and provides the precision-machined surfaces required for the pistons and piston rings to achieve efficient compression and combustion. Compared with conventional cast iron cylinders, Biral cylinders offer significantly improved cooling characteristics while retaining excellent wear resistance. Over time, repeated heat cycles, piston movement, and normal engine wear can cause cylinder bores to become worn, tapered, scored, or distorted, resulting in reduced compression, increased oil consumption, and declining engine performance. Replacing worn cylinders restores engine efficiency while benefiting from the superior cooling properties of Biral construction.  

What This Product Does:

• Provides precision-machined cylinder bores for the pistons.
• Restores engine compression and combustion efficiency.
• Combines cast iron wear resistance with aluminium cooling.
• Improves heat dissipation for stable engine temperatures.
• Supports correct piston and piston ring operation.
• Reduces oil consumption caused by worn cylinder bores.
• Replaces worn, scored, or damaged cylinders.
• Provides an OE-style fit for straightforward engine rebuilding.

Symptoms Of Wear Or Failure:

• Low engine compression.
• Excessive oil consumption.
• Blue exhaust smoke caused by oil burning.
• Loss of engine power or performance.
• Excessive crankcase blow-by.
• Scored, worn, or tapered cylinder bores.
• Piston slap or abnormal engine noise.
• Damage identified during engine overhaul.

Why Replacement Matters:

• The cylinders are fundamental to maintaining engine compression, efficient combustion, and reliable piston movement. As cylinder bores wear, engine compression decreases, oil consumption rises, and internal engine wear accelerates. Biral construction offers the added benefit of improved cooling performance while maintaining durable cast iron running surfaces, helping to reduce operating temperatures and improve long-term engine reliability.
• Replacing worn cylinders with this OE Match Biral Cylinder Kit restores compression, improves cooling efficiency, reduces oil consumption, and supports dependable engine performance. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Biral Cylinder Kit provides reliable fit, performance, and durability for classic Volkswagen and compatible Porsche engine maintenance, repairs, performance upgrades, and restoration projects.
