Walker 590-4005 Engine Variable Valve Timing (VVT) Solenoid Filter

Walker VVT Solenoid Filter for OE Oil Control

Walker Products 590-4005 is an OE replacement engine variable valve timing filter built to keep engine oil clean before it reaches the VVT solenoid actuator. It uses a stainless steel filter element with a rubber gasket to help maintain proper oil flow and cam timing control in Honda and Acura applications.

Key Features

• Stainless steel filter media for oil filtration at the VVT solenoid inlet
• Black rubber gasket for sealing in the original bore or housing
• Chrome filter finish
• Built to OE specifications for filtration efficiency and oil pressure compatibility
• Direct-fit service part for timing system maintenance

Detailed Description

This Walker VVT solenoid filter, part number 590-4005, is designed for engines that rely on precise camshaft timing control. By filtering oil before it enters the solenoid, it helps keep sludge, varnish, and fine metal particles from restricting flow. That matters on vehicles such as the 1994-2002 Honda Accord, 1997-1999 Acura CL, and 1998 Honda Odyssey, where clean oil delivery supports stable VVT operation and consistent drivability.

Walker 590-4005 is engineered for OE-style fitment and is made from high-temperature, oil-resistant materials for the engine environment. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

• Restricted oil flow to the VVT solenoid
• Timing-related drivability concerns
• Check engine lights tied to cam timing faults such as P0011 or P0014
• Contamination buildup from sludge, varnish, or metal particles
• Preventive maintenance during solenoid or timing service

Installation Notes and Tips

Install the filter into the original bore or housing and verify the sealing surface is clean before assembly. Inspect the VVT solenoid and surrounding oil passages for contamination so the new filter is not immediately restricted. For Honda Accord, Acura CL, and Honda Odyssey applications, confirm the engine uses this filter style before service.

Quality Assurance

Walker Products builds this filter to OE replacement standards for filtration, oil pressure compatibility, and fitment. The stainless steel filter and oil-resistant gasket materials are selected for the harsh internal engine environment.
