P1P S400 -12AN Duramax Turbo Oil Drain Kit LB7 LLY LBZ LMM LML L5P

This is the largest Duramax S400 turbo oil drain on the market! Todays high RPM diesels produce more oil volume and pressure then ever before. Having a free flowing low pressure exit for oil is crucial to turbo longevity. Nearly all high performance turbo manufacturers agree, the larger the drain, the less likely a turbo seal leak will develop. 

This setup is designed specifically to work on all 2001-2019 Duramax's.
