APR Valve Spring Kit Universal Single

APR Valve Spring Kit - Universal - Single

APR built its reputation on extracting reliable performance from turbocharged VAG engines, and the Valve Spring Kit is a good example of that engineering approach. Rather than simply fitting a stiffer spring, APR developed a matched spring, retainer and seat combination that controls valve float without overstressing the OEM valve or eroding the factory aluminium spring seat.

This listing covers a single APR Valve Spring Kit, SKU MS100258, sold as one unit rather than a full engine set. It suits engine builds where the factory valvetrain is the limiting factor at higher RPM or under increased boost, and where valve float is becoming an issue with the stock setup.

Key Features

• Matched valve spring, retainer and spring seat design
• Approximately 28% lighter than the OEM high performance EA113.K04 setup
• Approximately 20% stiffer than the OEM high performance EA113.K04 setup
• Designed to eliminate valve float without overloading the OEM valve or spring seat
• Sold as a single kit — multiples required for full engine builds

Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please ensure your engine specification and valvetrain configuration are confirmed before ordering.
