Specifically engineered for the legendary Rover V8, these headers are compatible with the 3.5L, 3.9L, 4.0L, and 4.6L variants across both Discovery Series 1 and Series 2 models. The Tri-Y design is the ideal choice for 4WD applications, as it is specifically tuned to improve mid-range pulling power—perfect for towing, off-roading, and highway cruising.
