Technical Details and Design Features

The E-441K piston ring set is engineered to meet the specifications of 96 mm bore diameter engines commonly found in select Ford and Mercury models. The top ring features a barrel face design made from steel with a molybdenum coating, which helps reduce wear and improve sealing under high temperature and pressure conditions. The second ring uses a reverse torsional face design and is constructed from durable grey iron to provide effective compression sealing and minimize blow-by gases.

The oil control ring is a 3-piece flex vent design with a width of 4.76 mm, optimized to maintain proper oil scraping and distribution along the cylinder walls. This configuration helps reduce oil consumption and prevents oil from entering the combustion chamber, contributing to cleaner engine operation.

This piston ring set is compatible with the following vehicles:

• Ford Capri
• Ford Mustang
• Ford Thunderbird
• Mercury Cougar

It is specifically designed for 4-cylinder engines with a 96 mm bore diameter, ensuring proper fit and function without the need for file fitting.

Common Engine Issues Addressed

• Reduced engine compression due to worn or damaged piston rings
• Excessive oil consumption caused by ineffective oil control rings
• Increased blow-by gases leading to decreased engine efficiency
• Engine smoking from oil entering the combustion chamber
• Loss of power and poor fuel economy related to ring wear

Installation Notes and Tips

• Verify engine bore diameter is 96 mm before installation
• Ensure cylinder walls are properly honed and clean
• Install rings carefully to avoid damage or distortion
