Introducing the OSBuyzone EH28943X-4-OS Headers for Nissan 350Z, 370Z, Infiniti G37 with 3.5L and 3.7L V6 engines. These headers are an excellent upgrade for those seeking improved performance and exhaust flow from their vehicles.

The OSBuyzone headers are made from high-quality steel, ensuring durability and resistance to corrosion. They feature a 4-2-1 design, which is known for its ability to provide a more balanced exhaust flow and better scavenging effect. This design helps to reduce backpressure within the engine, allowing for increased horsepower and torque.

One of the key benefits of these headers is their ability to provide a more efficient and complete combustion process. By improving exhaust flow and reducing backpressure, the headers help to ensure that more exhaust gases are expelled from the engine, resulting in better fuel efficiency and reduced emissions.

These headers also feature a 1 -inch primary tube diameter, which is larger than the stock headers, allowing for a more significant increase in exhaust flow. The collectors are also larger in diameter, further enhancing exhaust flow and reducing backpressure.

The OSBuyzone headers come with studs and gaskets included, making installation a straightforward process for most mechanically inclined individuals. However, it is recommended that the installation be performed by a professional to ensure proper fitment and function.

In summary, the OSBuyzone EH28943X-4-OS Headers for Nissan 350Z, 370Z, and Infiniti G37 are an excellent upgrade for those seeking improved performance and exhaust flow from their vehicles. Made from high-quality steel, featuring a 4-2-1 design, and offering larger primary tubes and collectors, these headers help to reduce backpressure, increase horsepower and torque, improve combustion efficiency, and enhance fuel efficiency.
