Jerbor plenum repair plate for Dodge Magnum 5.2L/5.9L (1992–2003) — 1/4" aluminum, corrosion‑resistant

The JERBOR 1/4" thickness aluminum plenum repair plate is a direct-fit replacement that reinforces the Dodge Magnum 5.2L and 5.9L plenum pan to stop oil leaks and restore reliable sealing.

Older Dodge Magnum engines commonly suffer plenum pan gasket failures that allow oil seepage and reduced engine reliability. This JERBOR plenum plate is engineered to match OE dimensions for 1992–2003 5.2L and 5.9L Magnum engines, offering a corrosion-resistant aluminum upgrade that resists bending and restores a stable mounting surface for the plenum gasket.

How does this plenum plate stop oil leaks?

The plate reinforces weak or damaged factory plenum pans and provides a flat, solid surface for the gasket to seal against, minimizing the pathways oil uses to escape. It resists deformation under engine heat and vibration, preserving the sealing surface over time.

• Thick 1/4" aluminum resists flexing under torque and heat.
• Fits to OE geometry to maintain correct gasket compression.
• Corrosion-resistant finish prevents pitting where leaks commonly start.

Will this part fit my Dodge Magnum from 1992–2003?

This JERBOR plate is made specifically for the Dodge 360 Magnum 5.2L and 5.9L engines produced between 1992 and 2003, matching original equipment specifications to ensure a proper fit. Confirm your engine model and year to ensure compatibility before ordering.

• Designed for 5.2L and 5.9L Magnum engines (Dodge 360).
• Manufactured to align with OE mounting points and bolt pattern.
• Sold as a single 1/4" thick repair plate—verify engine variant before install.

What materials and durability can I expect?

Constructed from high-quality aluminum, the repair plate resists corrosion and maintains shape under normal engine operating conditions. Its material choice offers long-term durability compared with thin factory stamped pans that often warp or develop cracks.

• Premium aluminum alloy resists rust and deterioration.
• 1/4" thickness prevents bending and improves gasket life.
• Engineered for repeated heat cycles without losing structural integrity.

How difficult is installation and what tools are required?

Installation is straightforward for someone experienced with engine repairs: no drilling or cutting is required—align the plate with existing bolt locations and torque to factory specifications. Professional installation is recommended if you’re not confident with gasket replacement procedures.

• Direct-fit—uses original bolt pattern; no modifications needed.
• Basic hand tools and torque wrench required; gasket replacement materials recommended.
• Follow factory torque specs and sealing prep for best results.

Who is this for? The JERBOR 1/4" plenum repair plate is intended for owners, mechanics, and restoration specialists working on Dodge Magnum 5.2L or 5.9L engines (1992–2003) who need a durable, OE-compatible fix for plenum pan gasket failure. It’s especially useful for vehicles with aged or warped factory pans where a corrosion-resistant, thicker replacement will restore sealing integrity and reduce future maintenance.
