This set of 8 exhaust manifold bolts secures the exhaust manifold to the engine cylinder head, preventing exhaust gas leaks and maintaining proper engine combustion. Manufactured from high-strength, heat-resistant alloy steel, these bolts resist stretching and fracturing under extreme engine temperatures, unlike worn or corroded fasteners. Operators may notice a persistent ticking or puffing sound from the engine exhaust area, a noticeable loss of engine power, or visible exhaust soot around the manifold connection if these bolts fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A ticking or puffing noise emanating from the engine compartment is the first sign. If ignored, exhaust gases can leak, leading to reduced engine performance and increased emissions. Continued operation with a leaking exhaust manifold can cause damage to surrounding components due to heat and soot exposure.
Ensure the cylinder head and manifold mating surfaces are perfectly clean and free of old gasket material or carbon buildup before installation. Overtightening these bolts can strip the threads in the cylinder head or cause the manifold to warp.
Inspect the exhaust manifold for cracks or warping and replace the gasket if it shows signs of damage or compression set.
