Overview

The Z Car Depot L4 Header is a stock replacement header designed for L-series 4-cylinder engines, specifically L16-L18 models. It features mild stainless primaries and a collector with square exhaust ports and a 1 7/8" collector size.

This header is recommended to be used with a Remflex gasket, as the header flange may not be completely flat, and the Remflex gasket can accommodate minor imperfections in fitment.
Show original supplier description
The Z Car Depot L4 Header is engineered as a direct stock replacement for L-series 4-cylinder engines, including L16, L18, and L20B variants. This header is specifically designed for applications on the Datsun 510 and 620 models. Constructed with mild stainless steel for the primaries and collector, this header features a 1 7/8" collector diameter and square exhaust ports. To ensure optimal fitment and compensation for potential minor imperfections in the header flange, the use of a Remflex gasket is highly recommended. While the product description focuses on the header itself, related items such as intake/exhaust gaskets and various engine-related components are also available from Z Car Depot to complement your build.
