Stage 4 Astra & Zafira VXR with K06 & Inlet Manifold

Our Stage 4 Conversion for Astra & Zafira VXR (Z20LEH) builds on the Stage 3 hardware components that are:

. Full Exhaust System, preferably 3” (76mm) throughout
. Large Intercooler

To this we add the following:

. K06 Hybrid Turbo
. Klasen High Flow Inlet Manifold
. Stage 4 Software
