Process West Isuzu D-Max

Front mount intercooler kits – bar and plate core kits listed for the 2013–2016 D-Max.

Intercooler hose kits – silicone hose kits offered for 2013–2016 (non-DPF) and 2016–2021 applications.

Air oil separators – SEPR8R and catch can style separators listed for MY16.5+ D-Max and the 2022+ D-Max / Mazda BT-50 platform.

Isuzu D-Max generations are commonly identified by build year rather than a single chassis code. Process West lists its D-Max parts as 2013–2016 (RC, pre-DPF and DPF variants), MY16.5+ (RG), and 2022+ (RG facelift, shared with the Mazda BT-50). Confirm your build date, engine (4JJ1 or 4JJ3) and whether a DPF is fitted, as the non-DPF hose kit is listed separately. Vehicles with an aftermarket bullbar, winch or auxiliary cooler may need the mounting arrangement checked before purchase.

Intercooler and hose kits generally require removal of the front bar or grille assembly, plus basic hand tools, sockets, hose clamp drivers and a trolley jack with stands. Air oil separators mount in the engine bay and tee into the factory PCV plumbing, so routing must be kept clear of heat sources and moving components. Installation by a professional workshop is recommended, and any modification should be assessed against your state's vehicle standards.

Will a 2013–2016 kit suit my MY16.5+ D-Max? No – the year ranges shown in the product titles are separate applications and are not interchangeable.

Does the 2022+ separator also suit a Mazda BT-50? Process West lists that SEPR8R for the 2022+ D-Max and BT-50, which share a platform.

Do I need a tune with an intercooler upgrade? An intercooler is a cooling upgrade rather than a power adder; tuning questions are best directed to your workshop or tuner.
