Complete extractor and 2.5″ exhaust kit for Toyota LandCruiser HZJ79 1HZ. Available in high-temp paint or ceramic-coated finishes for lasting performance and power.
Unlock reliable gains from your 70 Series with this complete Extractors & 2.5″ Exhaust package engineered specifically for the Toyota LandCruiser HZJ79 4.2L 1HZ. Replacing the factory cast manifold and restrictive pipework with tuned-length extractors and a mandrel-bent 2.5″ system improves flow, reduces back pressure and helps lower EGTs under load. Consequently, you’ll feel stronger low-down torque, smoother throttle response and a deeper, refined note on the highway. Built for touring and towing, this kit is a dependable, bolt-on upgrade for work and adventure.
Key Features
Vehicle-specific extractors matched to the Toyota 1HZ port geometry for efficient scavenging and improved cylinder balance.
