Information
Cylinder Kit, Biral, 81mm.
Restore dependable engine performance and benefit from enhanced cooling with this OE Match Biral 81mm Cylinder Kit. Produced to OE-style specifications, this premium Biral cylinder kit is designed for compatible classic Volkswagen air-cooled engines and Porsche applications using the same engine platform where applicable. Featuring cast iron cylinder liners permanently bonded to aluminium cooling fins, the Biral construction combines the outstanding wear resistance of cast iron with the superior heat dissipation of aluminium. Precision manufactured for accurate fitment and long service life, this cylinder kit is ideal for engine rebuilds, performance upgrades, and concours-quality restoration projects.
Fits:
The cylinder kit forms the combustion chamber walls, providing the precision-machined surfaces required for efficient piston movement, compression, and combustion. Compared with conventional cast iron cylinders, Biral cylinders provide significantly improved thermal management, helping maintain lower and more consistent operating temperatures under demanding conditions. Over time, continual piston movement, heat cycles, and engine wear can cause cylinder bores to become scored, tapered, or worn, leading to reduced compression, increased oil consumption, and declining engine performance. Replacing worn cylinders restores engine efficiency while benefiting from the improved cooling characteristics of Biral construction.

Over time, continual piston movement, heat cycles, and engine wear can cause cylinder bores to become scored, tapered, or worn, leading to reduced compression, increased oil consumption, and declining engine performance. Replacing worn cylinders restores engine efficiency while benefiting from the improved cooling characteristics 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 operating temperatures.
- Supports correct piston and piston ring operation.
- 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 engine performance, providing the precision-machined sealing surfaces required for efficient combustion and reliable piston movement. As cylinder bores wear, engine compression falls, oil consumption increases, and internal engine wear accelerates. Biral cylinders offer the added advantage of superior heat dissipation while maintaining durable cast iron running surfaces, helping improve thermal stability and engine longevity.
- Replacing worn cylinders with this OE Match Biral 81mm Cylinder Kit restores compression, improves cooling efficiency, reduces oil consumption, and supports long-term engine reliability. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Biral 81mm Cylinder Kit provides reliable fit, performance, and durability for classic Volkswagen and compatible Porsche engine maintenance, performance upgrades, repairs, and restoration projects.
