Product worked as expected. Great delivery time.

I purchased a Mahle Original turbocharger the box came sealed from the manufacturer. The order was processed in a timely manner and the product arrived within 5 days. Thank you.

Everything went well. I'm not sure why a blower fan would be made with any metal that could corrode and yet that's what happened to the old one that is NOT that old.

Good to go

Thx

Very efficient
