Fel-Pro Valve Cover Gasket Set VS 50900 R for INFINITI G37 & Nissan VQ Engines — Cork-Rubber Complete Kit

Fel-Pro VS 50900 R is a complete valve cover gasket set engineered to restore a secure, oil-tight seal on INFINITI G37 and compatible Nissan VQ engines.

When a leaking valve cover gasket creates oil seepage, smoke, or a burning-oil smell, the VS 50900 R kit from Fel-Pro supplies the vehicle-specific pieces and material technology needed to replace worn seals. This set is designed for the realities of automotive repair: it accommodates imperfect sealing surfaces, includes all required components for the job unless noted otherwise, and uses a cork-rubber formulation chosen to conform and resist oil and heat. Fel-Pro validates parts with on-vehicle testing so installers and DIYers get a reliable fit and long-term performance.

What vehicles and engines is this Fel-Pro gasket set compatible with?

The VS 50900 R covers several Nissan and INFINITI models that use the VQ-family engines. Compatibility spans model years and trims, so always verify fitment using your vehicle details before ordering.

• Fits Nissan 370Z (2009–2020) and select INFINITI models including G37 applications
• Also fits INFINITI M37, EX37, FX37, Q50, Q60, Q70, QX50 and QX70 across listed years
• Check year, make, model, engine and trim against the seller’s confirmed fit tool for final assurance

How does this gasket set handle imperfect sealing surfaces?

Fel-Pro engineered the VS 50900 R with a highly conformable cork-rubber compound that adapts to surface irregularities left from previous sealant or minor warpage. That flexibility helps achieve a consistent contact area and reduces the chance of leaks after installation.

• Cork-rubber formulation resists compression set and maintains sealing force
• Material tolerates engine oil, heat cycling, and vibration typical of VQ engines
• Designed to compress into minor surface defects for better real-world sealing

What parts are included and what should I expect in the kit?

Fel-Pro’s kit approach supplies the components commonly needed for a valve cover service to minimize sourcing extra parts. Unless the listing explicitly notes exclusions, you can expect the set to include all gaskets and small seal pieces required to reseal the valve cover assembly.

• Main valve cover gaskets molded to match OEM ports and bolt cutouts
• Secondary seals and small grommets where applicable to the engine design
• On-vehicle tested fitment to help ensure correct installation and performance

Why choose Fel-Pro over a generic replacement gasket?

Fel-Pro develops gaskets for the repair environment with industry-specific materials and validation that reflect real engine conditions. The company’s focus on application-specific formulations and on-vehicle testing reduces the guesswork compared with off-the-shelf generic pieces.

• Application-specific materials designed for VQ-family sealing challenges
• Tested on vehicles to verify sealing and fit before shipment
• Reputation among professional mechanics for durability and consistent performance

Who is this for? The Fel-Pro VS 50900 R valve cover gasket set is intended for mechanics and experienced DIYers maintaining Nissan 370Z and the listed INFINITI models who need a dependable, application-specific replacement. It’s a good choice when you’re replacing a leaking valve cover gasket, performing routine engine maintenance that requires valve cover removal, or preparing a vehicle for sale and you want a durable, professionally engineered seal. Always confirm exact fit using your vehicle’s year, make, model, engine, and trim before purchasing to ensure compatibility.
