Performance Insight
The 1.3L Toyota 4K engine at 4000 rpm draws approximately 2,700 L/min of intake air and expels around 8,100 L/min of exhaust gas. These headers optimise scavenging and gas velocity within that range, improving drivability and mid-range torque for daily use or classic performance builds.
Installation Tips
Lubricate bolts and studs with WD40 or anti-seize compound before fitting. Check gasket alignment and flange flatness before tightening. Retorque after the first heat cycle to ensure a leak-free seal.
Recommended With
- Gasket – see DSF024

Why Choose Hurricane Headers?
All Hurricane Headers are made in Australia and feature non-protruding secondary pipes for smooth collector flow. Some headers include Merge Emulation Spikes to enhance the scavenging effect, improving cylinder evacuation and power output.
