HDJ79/78/76 Fitment details:
- This airbox is designed to suit aftermarket CT26-Based turbocharger upgrades such as Gturbo, UFI, Arashi, etc with a larger, straight inlet.
- The fitting kit supplied will not suit the factory CT20B turbocharger on a HDJ70 Series. It does not suit the factory turbocharger. We do not recommend buying it for the factory turbocharger.
HZJ79/78/75 Series Fitment Details:
- May not fit Denco, DTS, Safari and other older style 1HZ turbo kits that do not use a CT26 Turbocharger. Design of this Airbox is based on our HD Auto Turbo kit, utilising a CT26 Turbocharger and factory 1HD Manifold position. If you have one of these turbo kits we recommend upgrading, or looking carefully at the photographs and doing some research before placing an order.
Fitment Details:
- 4″ Inlet/Outlet – Suitable for Safari Armax or 4″ Stainless Steel Snorkel
- Please specify the turbocharger used on your vehicle so that the correct silicone adapters can be supplied.
