Dorman VVT Solenoid 916-886XD OE FIX Replacement with Patented Copper Core and Direct-Fit Hardware

This OE FIX VVT solenoid addresses common failure points found on original equipment parts by using a patented copper core, strengthened center tube, and revised oil passages to reduce internal movement and improve oil flow. It ships with installation hardware and a gasket so technicians and DIYers can complete the repair in one visit. Use the vehicle fit tool to confirm compatibility before purchase; some fitments require additional verification notes.

How does this Dorman unit differ from the factory VVT solenoid?

The 916-886XD replaces the original design with targeted improvements intended to extend service life and improve hydraulic performance. A patented copper core reduces unwanted internal movement while a stronger center tube and added oil passages help maintain consistent oil circulation through the adjuster.

• Patented copper core minimizes internal vibration and wear.
• Stronger center tube resists deformation under load.
• Additional oil passages support improved flow and actuation.
• Comes with high-grade installation hardware and a gasket.

Will installing this part improve VVT performance on my vehicle?

Replacing a failing or worn VVT solenoid with this OE FIX version can restore expected hydraulic response and timing control by eliminating the common internal issues that cause erratic actuation. It is engineered to match the original mounting and connector while offering improved internal durability.

• Restores consistent oil control for VVT actuation.
• Improved internal stability reduces intermittent operation.
• Direct-fit design simplifies installation on specified models.
• Includes gasket and hardware to complete the repair correctly.

What do I need to know before buying and installing this solenoid?
