DJ Rock EV4263 Engine Exhaust Valve

Overview

DJ Rock EV4263 is a premium engine exhaust valve for Volvo applications that require a direct-fit replacement. It is built to control exhaust gas release from the combustion chamber and support consistent engine breathing.

This exhaust valve is specified for multiple Volvo S60, V60, XC60, C30, C70, S40, V50, V70, XC70, S80, XC90, and S70 applications. The EV4263 part number appears throughout the fitment range for 1999-2016 Volvo models.

Key Features

• Precision-engineered exhaust valve for valvetrain service
• Application-specific direct-fit replacement
• Premium grade type for demanding engine environments
• Heat-resistant alloy construction for exhaust-side temperatures
• Black nitride coating for added wear resistance and corrosion protection
• Designed to maintain valve integrity under thermal and mechanical stress

Detailed Description

DJ Rock EV4263 is an engine exhaust valve engineered for direct replacement in compatible Volvo engines. As an exhaust valve, it opens and closes to release burnt gases into the exhaust system, helping the engine complete each combustion cycle efficiently. The EV4263 uses heat-resistant alloy materials and a black nitride surface treatment to improve durability, reduce friction, and resist corrosion in high-temperature operation.

Fitment includes 2013-2016 Volvo S60, 2016 Volvo S60 Cross Country, 2015-2016 Volvo V60, 2015-2016 Volvo V60 Cross Country, 2015-2016 Volvo XC60, 2016 Volvo XC70, 2008-2013 Volvo C30, 2006-2013 Volvo C70, 2012 Volvo S60, 2001-2009 Volvo S60, 2011 Volvo S40, 2011 Volvo V50, 2004-2010 Volvo S40, 2005-2010 Volvo V50, 2000-2007 Volvo V70, 2003-2007 Volvo XC70, 2004-2006 Volvo S80, 2003-2006 Volvo XC90, 2000-2004 Volvo C70, 2000-2004 Volvo S40, 2000-2004 Volvo V40, 2000-2003 Volvo S80, 2000 Volvo S70, 1999 Volvo C70, 1999 Volvo S70, and 1999 Volvo V70. Notes include 6mm stem applications and exhaust-side listings where specified.

This part cross-references no interchange numbers provided for the same application.

What It Helps Address

• Burnt exhaust gases not exiting the combustion chamber cleanly
• Valve wear from repeated high-heat operation
• Corrosion on exhaust-side valvetrain components
• Friction-related valve surface deterioration
• Thermal fatigue that can affect valve sealing and stability

Installation Notes

Verify stem diameter, valve location, and engine application before installation. Several listings specify a 6mm stem, and some rows note exhaust-side use. Match the valve to the exact Volvo engine configuration shown in the fitment data for proper service.

Quality Assurance

DNJ states that these exhaust valves are manufactured to meet or exceed OEM quality standards. The EV4263 is a premium-grade component built with materials and coating choices intended for long-term durability in severe engine conditions.
