An aluminum turbo inlet pipe for the B58 Gen 2 in the BMW M340i, M440i, M240i and the Toyota GR Supra 3.0. It replaces the factory inlet pipe — the bend that carries air from your intake into the turbo — with a high-flow aluminum part in a gloss black finish, with the breather port welded in place.
Why change it
The inlet is the last section of pipe before the turbo. Swapping the factory part for a smooth, high-flow aluminum one is a common next step after an intake, and it's the kind of part that holds up as you add a tune later.
Sound: most owners notice a little more turbo spool when they get on the throttle, especially paired with an intake. Power: on its own, on a stock tune, expect small changes — it's a supporting mod, not a power adder by itself.
Pairs with our B58 cold air intake for the M340i, M440i and M240i.

Fitting
It goes in where the factory inlet comes out. If you're comfortable taking your intake off, you can do this at home with hand tools; if not, any shop that works on BMWs or Supras can fit it quickly.
