The intake and exhaust manifolds are made from aluminum, which is lightweight and durable, while the camshafts are made from high-strength steel. These materials provide excellent heat dissipation, ensuring that the engine stays cool under heavy use.

Installing this top end set is a straightforward process, making it an ideal upgrade for DIY enthusiasts. The set comes with all necessary hardware, including gaskets, bolts, and nuts, making the installation process as seamless as possible.
