⚠️ Expert Installation Tips for JCB Owners

1. Oil Priming: Before the first start, pre-fill the turbocharger oil inlet with clean engine oil to prevent dry-start wear.
2. Air Filtration: On construction sites, dust is the #1 killer of turbos. Always replace the air filter when installing a new unit.
3. Exhaust Gaskets: Use only high-quality steel gaskets for the manifold connection to prevent boost leaks that can lead to power loss.
