A-Premium Intake Manifold Gasket Set for DOHC 4.3L & 4.7L V8 — Upper & Lower, Metal + Asbestos-Free

The A-Premium Lower & Upper Engine Intake Manifold Gasket Set is a direct-replacement, asbestos-free gasket kit engineered to restore a reliable seal for DOHC 4.3L and 4.7L engines.

When intake manifold leaks develop they can cause rough idle, reduced efficiency, and drivability issues. This A-Premium kit contains the metal and composite gaskets required to replace both lower and upper intake surfaces on select Lexus and Toyota V8 engines. Each component is made to meet OEM fitment and withstand the heat, pressure, and chemical exposure found in the intake system, making it a practical repair part for maintenance or restoration projects.

Which vehicles and engine types does this gasket set fit?

This kit is designed for specific Toyota and Lexus V8 models with DOHC 4.3L and 4.7L engines produced in late 1990s through mid-2000s. Confirm year and production cutoff dates to ensure compatibility before ordering.

• Reference number for lookup: MS96334.

What materials and components are included in the package?

The set combines metal and asbestos-free composite gaskets to create a durable, heat-resistant seal. It ships in a box with the correct quantity and types of gaskets needed for a full upper and lower intake replacement.

• Included parts: 1 metal intake manifold gasket, 1 asbestos-free lower gasket, 2 asbestos-free upper gaskets (package quantity: 1 set).
• Materials: high-grade metal and asbestos-free composite designed for high temperature and gas corrosion resistance.
• Color and packaging: black gaskets, boxed packaging for protection during shipping.

How does this kit improve engine performance and longevity?

A properly sealed intake manifold prevents unmetered air from entering the engine and helps maintain correct air/fuel ratios. Replacing old or damaged gaskets reduces vacuum leaks, supports stable idle, and helps avoid lean conditions that can stress ignition and emission systems.

• Sealing performance: prevents air leakage between manifold and head.
• Durability: materials resist high temperatures, pressures, and corrosive gases.
• OEM fitment: engineered for direct replacement to simplify installation.

What should I know before attempting installation?

Basic mechanical skills and common hand tools are sufficient for many users, but some disassembly of intake components and accessories is required. Clean mating surfaces thoroughly and follow torque specs—improper installation can cause leaks or component damage.

• Preparation: inspect and clean intake and cylinder head mating surfaces before installing gaskets.
• Tools: common hand tools and a torque wrench recommended for correct clamp sequence and torque values.
• Note: check vehicle-specific repair manuals for exact torque specs and sequence.

Who is this for: Mechanics, DIY-enthusiasts, and restoration shops working on late-1990s to mid-2000s Toyota and Lexus V8s who need a reliable, direct-replacement intake manifold gasket set. If you want an asbestos-free, OEM-fit option to address intake manifold leaks and restore correct engine sealing, this A-Premium set provides the components and materials required for a long-lasting repair backed by a one-year unlimited-mileage guarantee.
