B58 Charge Pipe
The F-series B58 kit: charge pipe and inlet pipe for one engine and chassis, confirmed item by item.
The B58 charge pipe kit is the charge pipe family's documented detail: a B58 F-series charge pipe and inlet pipe for the 340i, 440i and 540i on the 3.0T engine. What the kit is, the cars it fits, and how its contents are confirmed are stated in full, because in this family the confirmation is a step of the order.
The neighbouring BMW kits are the N55 intercooler and charge pipe kits for the F20, F30 and F32, and the N20 charge and boost pipe kits for the F2X and F3X cars. All are order-book items, in the same position as the B58 kit. The N55 combination pairs its charge pipes with a front-mount intercooler for the same cars, so the whole front-end run — cooler, charge side and inlet side — can be confirmed as one specification.

What the B58 Kit Contains
The B58 kit pairs a charge pipe and an inlet pipe for the F-series cars. In kit terms that is the pressure-side run the turbo feeds and the intake-side pipe that feeds the turbo — the two halves of the induction pipework for the engine, offered in one program. Piping materials across the family are aluminium and titanium; the material of a given kit is stated in the confirmation, not assumed from the family.
The cars are named by their model designations — 340i, 440i, 540i — on the 3.0T engine. Chassis generation is part of the confirmation, because the F-series cars share an engine across several chassis whose pipe routing differs in detail.
| Kit element | Specification | Confirmation point |
|---|---|---|
| Charge pipe | B58 F-series charge pipe | Chassis code checked against the kit |
| Inlet pipe | B58 F-series inlet pipe | In the charge pipe program |
| Neighbouring kits | N55 intercooler + charge pipe; N20 charge + boost pipe | F20/F30/F32 and F2X/F3X cars |
| Material | Aluminium and titanium both appear across the family | Stated per kit in the reply |
How Confirmation Works for This Kit
Send the vehicle, engine code and chassis code. The workshop matches them to the documented kits and replies with the kit contents for your combination — which pipes, which joints, which material — so the quotation is for a named kit. If your chassis is a sibling of a documented one, the reply says whether the kit covers it, adapts to it, or would be a development job. The same confirmation covers the neighbouring combinations a B58 inquiry often arrives with: the Mini Cooper S charge and boost pipes for the F45 to F57 cars, the MQB discharge and charge pipes for the Golf 7 on the EA888, and the B48 inlet pipes — each confirmed against its own engine and chassis in the same reply.
That discipline is the family's answer to its own position: the written confirmation is what turns a kit name into a specification. Nothing is quoted from a name alone.
Ordering With the B58 Exhaust Program
The B58 downpipe is the exhaust-side counterpart of this kit, and the two are often ordered together for the same cars. A combined inquiry — induction kit and front section for one chassis list — is confirmed as one program, with the kit contents and the downpipe variant priced side by side.
