Genuine Mazda Inlet Manifold Gasket – MX-5 Mk3 / NC • LFE2-13-111

Genuine Mazda LFE2-13-111 Inlet Manifold Gasket

Replacement Genuine Mazda lower inlet manifold gasket for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models with applicable 1.8L and 2.0L petrol engines listed in the compatibility table.

The gasket fits between the lower inlet manifold and engine cylinder head, sealing the individual inlet passages against air leakage.

A correctly sealed manifold ensures that air entering the engine passes through the intended intake and throttle system, allowing the engine-management system to calculate fuelling accurately.

A damaged, compressed or incorrectly seated gasket may allow unmetered air into the engine and contribute to rough idle, lean running, hesitation, reduced performance or an engine-management warning.

This listing supplies one Genuine Mazda lower inlet manifold gasket, which seals the complete manifold-to-cylinder-head joint.

• Part type: Lower inlet manifold gasket
• Mazda catalogue description: Gasket, inlet manifold
• Alternative descriptions: Intake manifold gasket / inlet manifold-to-cylinder-head seal
• Primary function: Seals the inlet manifold to the cylinder head
• System: Engine air-intake system
• Fitting position: Between the lower inlet manifold and cylinder head
• Primary vehicle application: Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC
• Engine applications: Applicable 1.8L L8-DE and 2.0L LF-VE petrol engines
• Transmission applications: Manual and automatic according to vehicle specification
• Quantity required per engine: One complete gasket
• Quantity supplied: One gasket
• Brand: Genuine Mazda
• Part No.: LFE2-13-111
• Also referenced as: LFE213111

Typical reasons for replacement:

• Inlet manifold removed during engine repairs
• Vacuum or unmetered-air leak around the manifold joint
• Rough or unstable idle
• Lean-running fault code
• Hesitation or reduced engine response
• Gasket compressed, split or hardened
• Seal damaged during manifold removal
• Inlet manifold or cylinder-head work being undertaken

Fitment advice: This is the lower inlet manifold gasket fitted between the manifold and cylinder head on applicable MX-5 NC 1.8L and 2.0L engines.

Related-gasket advice: This component should not be confused with the separate surge-tank gasket LFE2-13-135 or throttle-body gasket LFE2-13-655. Consider replacing any additional disturbed intake-system gaskets during the same repair.

Single-use advice: Replace the gasket whenever the inlet manifold is removed. Reusing a compressed gasket can result in an air leak after reassembly.

Inspection advice: Inspect the inlet manifold and cylinder-head sealing faces for corrosion, distortion, damage or remnants of the old gasket.

Cleaning advice: Carefully remove old gasket material without allowing debris to enter the inlet ports. Do not gouge or excessively abrade the sealing faces.

Sealant advice: Install the gasket dry unless the applicable Mazda workshop procedure specifically instructs otherwise. Unspecified sealant can interfere with correct gasket compression or enter the intake system.

Vacuum-hose advice: Inspect all vacuum hoses, breather hoses, manifold fittings and clamps while the manifold is removed. A split hose can produce symptoms similar to a failed manifold gasket.

Fuel-system advice: Depending on the repair procedure, access may require disturbing fuel-system components. Relieve fuel pressure and observe the appropriate precautions before disconnecting any fuel line or injector-rail component.

Diagnostic advice: Intake leaks are only one possible cause of lean running or poor idle. Check the airflow meter, throttle body, vacuum system, injectors, ignition system and engine compression where symptoms remain after replacement.

Other items to consider: Consider inspecting or replacing the surge-tank gasket, throttle-body gasket, injector seals, vacuum hoses, breather hoses and manifold mounting hardware according to their condition.

Useful tools / consumables: Socket and spanner set, torque wrench, hose-clamp pliers, gasket scraper suitable for aluminium surfaces, lint-free cloths and suitable intake-system cleaner.

Difficulty guide: DIY Difficulty: Advanced. Replacement requires removal of the inlet manifold and associated intake, electrical, vacuum and potentially fuel-system connections.

Why Genuine Mazda? Genuine Mazda inlet manifold gaskets are manufactured to the intended port shape, material specification, thickness and mounting geometry. Using the correct OE gasket helps maintain an airtight manifold joint and compatibility with the original engine components.

What’s in the box: One Genuine Mazda lower inlet manifold gasket, part number LFE2-13-111. Surge-tank gasket, throttle-body gasket, injector seals, manifold, mounting hardware and installation tools are not included unless specifically shown or stated separately.

Installation notes: Allow the engine to cool and disconnect the battery where required. Remove the necessary intake ducting, electrical connections, hoses and manifold hardware using the applicable Mazda procedure. Remove the old gasket, clean and inspect both sealing faces and install the replacement in the correct orientation. Refit the manifold and tighten its fasteners progressively in the specified sequence and to the applicable torque. Reconnect all hoses and electrical components, then check carefully for air, fuel or coolant leaks before road testing.
