Dtomi Engine Valve Cover & Upper Intake Gasket Set for Nissan/Infiniti 3.5L (Altima, Maxima, Murano, I35, Quest) - Direct Replacement

Dtomi presents a 100% brand-new Engine Valve Cover Gasket Set with Upper Intake/Plenum Gasket, designed for select Nissan and Infiniti 3.5L engines. This direct replacement kit includes 2 valve cover gaskets and 1 upper intake/plenum gasket set, ready to install on compatible models.

Engine bays can be unforgiving, but this gasket set aims to restore sealed performance with durable materials and a precise fit.

This combination supports a reliable seal under demanding driving conditions.

What you get and how it helps:

• 2 valve cover gaskets and 1 upper intake/plenum gasket set, covering the essential sealing points on the engine’s top end.
• Direct replacement design reduces guesswork and makes installation straightforward for compatible vehicles.
• 100% brand-new components, tested for quality, with a one-year support window for added confidence.
