Understanding the Datsun 280Z
The Datsun 280Z, produced from 1975 to 1978, is part of the Z-car lineage known for its blend of performance and affordability. With a 2.8-liter inline-six engine, the 280Z was designed for both daily driving and spirited performance. However, like many vehicles of its time, it can benefit from modern upgrades.
What is a K&N High-Flow Air Filter?
K&N is a well-known brand in the automotive aftermarket, specializing in air filters that enhance engine performance. Their high-flow air filters are designed to increase airflow while providing excellent filtration. This results in better engine efficiency and potentially increased horsepower and torque.
Benefits of Upgrading to a K&N Air Filter
Upgrading to a K&N high-flow air filter can provide several benefits for the Datsun 280Z, including:
- Improved Airflow: K&N filters are designed to allow more air into the engine, which can enhance combustion efficiency.
- Increased Horsepower: Many users report noticeable increases in horsepower after installation.
