Important Installation Notes

Turbocharger Installation:

1. Replace/repair/reconnect air cleaner element per manufacturer's manual to prevent compressor wheel damage.
2. Ensure the oil drain line is mounted lower than the turbocharger for proper oil flow.
3. Fully seal exhaust outlets with welding to eliminate leaks and maintain performance.
4. Professional installation is highly recommended – this is a universal turbo, and minor modification may be required for your specific vehicle.
5. Verify all specifications and vehicle compatibility before purchase – this turbo is not vehicle-specific.
6. Prior to installation, identify and fix the root cause of any previous turbo failure (e.g., insufficient oil supply, intake foreign bodies, faulty crankcase ventilation).

Heat Shield Installation:

1. Universal fit for all T6 exhaust housing turbos – direct application for all T6 turbo setups.
2. This product is non-flammable but may ignite if exposed to flammable fluids; keep all fluids away from the shield.
3. Inspect all oil supply lines and fluid fittings for proper function, tight seals, and zero leaks before and after installation.
