To reduce carbon buildup inside the cylinders, the ISX engine introduced cylinder liners equipped with anti-polishing rings. We strongly recommend purchasing the new-generation piston and liner kits. If your engine’s pistons and liners show significant wear and need to be replaced, it's usually a sign that all pistons and liners within the engine should be replaced at the same time. In such cases, we advise upgrading to the new piston and liner design. Our products are made from high-strength steel to increase tensile strength and wear resistance, ensuring greater durability. In addition, they are treated with phosphate coating and induction hardening, which help improve wear resistance and performance during engine break-in.

For a critical engine component like the exhaust manifold, we recommend choosing a high-quality supplier like us. When the exhaust manifold becomes severely corroded, cracked, or deformed, it may lead to exhaust leaks. In such cases, we advise replacing the manifold promptly to ensure your engine continues to operate smoothly.

We have developed both cast iron and stainless steel exhaust manifolds for the ISX CM570 engine. The part numbers are as follows:
MANIFOLD-EXHAUST (CENTER)--3680199
MANIFOLD-EXHAUST (END)--3680200

Both cast iron and stainless steel versions are highly durable, as we use reliable raw materials and optimized. Cast iron manifolds offer a more cost-effective option and are more reliable under frequent cold-hot fluctuations. Stainless steel manifolds perform better in high-temperature and corrosive environments, making them more suitable for high-performance engine applications.
