Try MAZDA part # FD01-61-214A

Be sure to re-use the OEM spring clamps. And I’d cover that primary turbo inlet...you wouldn’t want anything foreign accidentally falling in and not realizing it until it’s too late.

Its a borrowed picture i was just using it as reference but thankyou im missing the hardline as the previous owner has binned it i was just going to buy some new reinforced hose and re-route it away from my turbo ibe got plenty over room as i dont have the twins
