Why Upgrade to Extractors?

The factory Hilux 3Y cast manifold is restrictive and often prone to cracking with age. Upgrading to extractors provides more efficient exhaust gas evacuation, leading to better drivability, improved mid-range torque, and a smoother overall engine feel. Perfect for work utes, restorations, or anyone wanting better response from their classic Hilux.
