Process West Toyota HiLux N70 / N80

Front mount intercooler kits – bar-and-plate style cooling upgrades listed for the HiLux N70 and, under the Terratuff by Process West banner, the HiLux N80.

Air oil separators – SEPR8R and Process West catch-can style separators designed to capture oil mist from the crankcase ventilation system before it reaches the intake tract, which is a common consideration on modern common-rail diesels.

Hoses and fitting hardware – supporting silicone hoses, clamps and brackets are supplied with, or offered alongside, the relevant kits. Check each product page for the exact inclusions.

Toyota HiLux generations are identified by chassis code rather than trim name:

• N70 – seventh-generation HiLux, sold in Australia from 2005 to 2015, including the 3.0L 1KD-FTV turbo-diesel.
• N80 – eighth-generation HiLux, from 2015 onwards, including the 2.8L 1GD-FTV turbo-diesel. Some listings specify a 2016–2023 build range.

Confirm your build date, engine code and whether the vehicle has any aftermarket bar work, winch or auxiliary cooler already fitted, as these can affect front-mount intercooler packaging. Always read the fitment notes on the individual product page before ordering.

Intercooler kits generally require removal of front bar and grille components, relocation or trimming of factory ducting, and routing of new piping. Air oil separators mount in the engine bay and tee into the factory crankcase ventilation plumbing, so hose routing and secure bracketry matter.

Typical requirements include a metric socket and spanner set, trim removal tools, hose clamp drivers, a torque wrench and a safe way to support the vehicle. Installation by a professional workshop is recommended, and any part that affects emissions equipment or intake plumbing should be checked against your state or territory's vehicle standards.

Will an N70 kit fit an N80 HiLux? No. The two generations use different front-end structures and intercooler locations, so use the kit listed for your chassis code.

Do I need a tune after fitting an intercooler? An intercooler upgrade is a cooling change rather than a fuelling change, but many owners pair it with tuning. Speak with your tuner about your combination.

What does an air oil separator do? It separates oil vapour from crankcase gases so less oil mist is carried into the intake system. Servicing intervals vary with use, so check the drain or filter regularly.
