exhaust manifold gasket 8941395280 8971464990 suitable for NPR models, equipped with 4HF1, 4HG1, 4HK1 engines

Product Design Philosophy

Multi-layer steel exhaust manifold gasket for 4HF1/4HG1/4HK1 engines. Designed to withstand extreme exhaust temperatures and pressure, ensuring reliable sealing between manifold and cylinder head.

How it works

Installed between exhaust manifold and cylinder head. The multi-layer steel construction compresses under bolt torque to seal high-temperature exhaust gases, preventing leaks that cause noise and power loss.

Problems the product can solve

Fixes exhaust leaks, ticking noises, and turbo lag caused by blown manifold gaskets. Restores proper exhaust sealing, improves turbo efficiency, and reduces noise in NPR trucks.
