HPD 4JJ1 EGR Delete Plates – 2006–2012

 

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

 

Keep your early-model 4JJ1 running cleaner with these HPD CNC-machined EGR Delete Plates. Designed to fully block off the EGR cooler, they reduce soot build-up, lower intake temps and boost long-term reliability.

🧩 Overview

These HPD plates replace the factory EGR cooler connection, preventing exhaust gases from re-entering the intake. The result is a cleaner manifold, more consistent throttle response and a more reliable 4JJ1 — especially important on tuned or worked setups.

  • Holden Colorado RC — 4JJ1-TC (2008–2012)
