Installation suggestions

We highly recommend you make sure the points below before installing:
1.Replace the air filter: if the if the air filter is not replaced may cause the compressor wheel damage.
2.Replace the engine oil: Because floating bearing and turbocharger will be damaged by impurities in the old oil.
3.After large overhaul, the engine cannot be replaced with a new turbocharger because there are too much impurities in oil after overhauling which will damage the replacement turbocharger immediately.
Please run the old turbocharger for 7-10 days and then replace to new turbocharger and new engine oil.


- Please check the Turbo Model, Turbo Part Number and OEM Part Number on your original Turbo to make sure this turbo is the correct one for your engine. If you need assistance finding the correct turbo for your car, please feel free to contact us.
- Professional installation is highly recommended (No Instructions are Included)
