- Review the turbo’s OEM reference matches to confirm it aligns with your vehicle’s engine code and model year.
Storage & logistics
For garages and workshops, storing remanufactured turbos requires controlled conditions to preserve internal components. Keep units in their original packaging until installation, away from moisture and extreme temperatures. Rotate stock based on expiry dates if applicable, and inspect seals for damage before handling. For bulk orders, use shelving that prevents vibration and ensures easy access to high-turnover models like the 18d SDrive’s turbos.
