Stone JB-42331 Exhaust Manifold Gasket

The Stone JB-42331 is an exhaust manifold gasket engineered to OE specifications for Honda applications. Manufactured by Ishino Stone — a Japanese OEM supplier with decades of experience in engine sealing technology — this gasket delivers a precise, leak-free seal between the exhaust manifold and cylinder head.

Key Features:

• OE-quality construction — designed and manufactured to original equipment specifications for a direct-fit replacement
• Asbestos-free materials — constructed with modern, non-asbestos compounds for safe handling and environmental compliance
• High heat resistance — engineered to withstand the extreme temperatures and pressures of the exhaust system
• Precision fit — maintains a consistent seal to prevent exhaust leaks, ticking noises, and combustion gas intrusion
• Made in Japan — produced by a trusted OEM-level gasket manufacturer

Replacing a worn or damaged exhaust manifold gasket restores proper exhaust flow, eliminates exhaust leaks, and helps protect downstream components including the catalytic converter. The Stone JB-42331 is sold individually and is a reliable, cost-effective alternative to dealership OEM pricing.
