🔧 Yamaha 100 Intake Manifold Gasket

📦 Part Number: MIYP100-5090B

🔩 Intake Manifold Insulator · JOG 100cc LY149QMG

📍 Installation Position: Between Intake Manifold and Cylinder Head

✅ High-Temp Material · Precision Seal · Direct Replacement · Prevents Air Leaks

📋 Product Overview

This product is a Yamaha 100 Intake Manifold Gasket (Intake Manifold Insulator), part number MIYP100-5090B. It is designed for JOG 100cc LY149QMG and similar engines, installed between the intake manifold and the cylinder head to provide sealing and thermal insulation.

This gasket sits between the head and the manifold. Like the manifold, these gaskets will crack over time and leak air, causing the engine to run poorly. We suggest you replace these whenever you change the manifold to avoid problems later. Keep these in stock!

✅ Quality Assurance: Manufactured from high-temperature and oil-resistant materials, precisely matched to OEM dimensions for long-lasting sealing performance.

🔧 Mechanic's Note

Why should you pay attention to the intake gasket?

This gasket sits between the cylinder head and the intake manifold, subjected to high heat and vibration.
Like the manifold itself, these gaskets will harden, crack, and deteriorate over time, causing air leaks.
Air leaks lead to rough idle, poor acceleration, increased fuel consumption, and even starting issues.
Recommendation: Always replace this gasket whenever you change the intake manifold to avoid future problems.
Keep these in stock for quick repairs!

⚙️ Product Features

🔩 Precision Dimensions: 50mm mounting hole spacing and 20mm inner diameter for a perfect match to OEM intake manifolds and cylinder heads.
🔥 High-Temperature Material: Constructed from quality oil-resistant and heat-resistant materials, maintaining reliable sealing in high-temperature engine environments.
🛡️ Reliable Sealing: Effectively prevents intake air leaks, maintains proper air-fuel ratio, and ensures consistent engine performance.
🔄 Direct Replacement: Fully compatible with the original factory gasket — simple installation with no modifications needed.
📦 Service Essential: The ideal companion part when replacing the intake manifold, saving you from a second disassembly.

✅ Typical signs that the intake manifold gasket needs replacement:
• Engine idles roughly or stalls frequently.
• Sluggish acceleration and noticeable power loss.
• Increased fuel consumption.
• Oil residue or hissing sound near the intake manifold.
• Visible cracks, deformation, or hardening of the gasket.
Replacing an aged gasket promptly restores proper intake sealing and engine performance.

✅ Installation Tips:
1. Ensure the engine is cool, then remove the intake manifold mounting bolts.
2. Remove the old gasket and clean the mating surfaces on both the cylinder head and manifold (remove old sealant or debris).
3. Position the new gasket between the head and manifold, aligning with the locating pins or mounting holes.
4. Tighten the mounting bolts in a crisscross pattern to ensure even pressure.
5. Check that the installation is level, start the engine, and inspect for air leaks (use carburetor cleaner spray around the joint as a test).
We strongly recommend replacing this gasket whenever you change the intake manifold to eliminate air leak risks entirely.
