Stop chasing leaks from undersized or poorly machined drain flanges. This 100mm billet 12AN turbo drain flange is precision-machined to fit right and seal right the first time.

Features & Benefits

• Exact 100mm bolt pattern fit — engineered specifically for mid-frame and large-frame turbochargers, so you're not forcing a universal flange to do a specific job.
• 12AN male port — connects directly to braided or hard-line -12AN oil return setups for a clean, leak-free oil drain back to the sump.
• Billet construction — machined from solid billet stock for superior strength and a precision sealing face that cast alternatives simply can't match.
• Clean sealing surface — the precision-machined face minimizes the risk of oil weeps and seepage at the turbo drain, keeping your build tidy under the hood.
• Designed and made in Canada — manufactured by BSI Inc. and shipped to builders across North America, with CAD pricing and no cross-border guesswork on your order.

Whether you're laying down a street build or pushing the limits on a competition setup, this is the drain flange that pulls its weight without compromise.
