HPD Front Mount Intercooler Kit – Isuzu D-MAX / MU-X 4JJ1 DPF (2016+)

🚚 Free Express AU 💳 Afterpay • Humm • Klarna • Zip 🛠 Direct Fit

Built for the late-model 4JJ1 DPF platform, this HPD FMIC drops intake temps, steadies EGTs and unlocks reliable torque for touring, towing and off-road use — all with bolt-on fitment.

🧩 Overview

Factory coolers heat-soak. HPD’s front mount relocates the core for cool, dense charge air under sustained load. Expect stronger mid-range, repeatable performance and tune-ready airflow.

Direct bolt-on replacement — no cutting, welding or permanent mods.

❓ FAQs

Is this a direct bolt-on?
Yes. It uses factory mounting points and OEM rubber mounts — no cutting or welding.
Do I need a tune?
No, but a quality remap will optimise fueling/boost to take full advantage of lower IATs and stabilised EGTs.
How do I confirm it’s the right kit?
Late DPF 4JJ1 typically has a bright red hot-side boost pipe. If you have this, this is the correct kit.
What core size is included?
Approximately 600 × 275 × 76 mm bar-and-plate core.
Is it good for towing?
Yes. The cooler maintains stable intake temps under load, improving consistency and protecting against heat-soak.
