The Wagner Tuning B58 EVO1 Intake Manifold Fuel Rail Kit is a high-performance upgrade designed for BMW and Toyota models running the first-generation B58 engine. Engineered to improve airflow, cooling efficiency and fuelling capability, this manifold is built for tuned, high-boost and track-driven B58 applications where the factory manifold becomes restrictive.

With a larger plenum, high-flow runners, integrated provisions for multi-port injection (MPI) and a motorsport-grade fuel rail, the EVO1 manifold provides the airflow and fuelling support required for hybrid turbo builds, ethanol setups and consistent performance under demanding conditions.


Key Features

  • Enlarged, high-flow aluminium plenum for improved cylinder filling

  • Optimised runner geometry for increased top-end power

  • Supports MPI (multi-port injection) – ideal for high-boost or ethanol builds

  • CNC-machined billet fuel rail included

  • Significant reduction in pressure drop vs OEM manifold

  • Increased airflow stability across all cylinders

  • Designed for hybrid turbos, upgraded HPFPs and high-power applications

  • Direct OEM replacement with factory sensor compatibility

  • TIG-welded aluminium construction for excellent durability

  • Suitable for both fast-road and track use


Compatibility

BMW B58 (Gen 1) Models

  • M140i (F20/F21)

  • M240i (F22/F23)

  • 340i (F30/F31/F34)

  • 440i (F32/F33/F36)

  • 540i / 640i (selected early models)

  • X3 M40i / X4 M40i (B58 Gen 1 variants)

Toyota

  • GR Supra A90 / A91 (3.0 B58 Gen 1)

(Not suitable for B58TU/B58 Gen 2 engines found in newer G-Series BMW models.)


Ideal For

  • Tuned B58 builds running Stage 2+, hybrid turbos or ethanol

  • GR Supra and M Performance models used for fast-road or track work

  • Drivers needing reliable MPI support for higher fuelling demand

  • Owners experiencing airflow imbalance or intake restriction on the OEM manifold

  • High-boost applications requiring consistent charge distribution and lower IATs


Why Choose the Wagner Tuning B58 EVO1 Intake Manifold Fuel Rail Kit

The factory B58 manifold is designed around efficiency rather than maximum flow, and it becomes a limiting component once boost, turbo size or fuelling demands increase. The Wagner EVO1 manifold solves this with an enlarged plenum, revised runner design and stronger materials capable of supporting significantly higher power levels.

Integrated MPI ports and the included fuel rail allow for improved fuelling safety and headroom — essential for ethanol blends, high boost and big-turbo setups. Wagner’s engineering quality ensures excellent fitment, stable airflow across all cylinders and reliable performance under heat and load.

For B58 owners targeting serious, sustainable power gains, the EVO1 manifold is one of the most effective supporting upgrades available.


Installing / Notes

  • Direct replacement for OEM manifold

  • Professional installation recommended

  • MPI hardware (injectors, lines, controller) not included unless specified

  • Custom ECU tuning required when adding MPI

  • Works with OEM and aftermarket intercooler/chargecooler systems

That ending 😫
Format: Kindle
I fell into a false sense of security and really thought this was gearing towards a happy ending. Then I realized there’s no work they don’t punish Andrew. I really liked Vale’s character. I don’t normally read books with pregnancy but going into this knowing she was pregnant made it more enjoyable for me. I loved Bishops devotion to her and her happiness. I also loved that Holt and Mercy couldn’t fight their attraction to her. I love scent matches so very much. I’m so curious to see how this duet will end up. And I need to pay more attention and notice that a book I’m starting is a duet to begin with lol

oh wow
Format: Kindle
I just knew there was something about Cooper! I’m wondering if he’s about to be included but damn I’m glad he’s at least not a rapist and creepy guy, he just got called on assignment and had to go! This should be interesting! She’s gonna run and then what’s his face is gonna grab her. I’m worried! Wow that was a great book and cliffhanger! Loving this!

Good start to a series
Format: Kindle
I delayed reading the series for reasons I don’t remember. But my TBR list is huge so I thought I’d take a shot of this and I was pleasantly surprised. I didn’t think the blurb about it was anything special. But it was a very good book. It took some interesting twists and turns. I am so glad the second book is already out. Because I would not have waited patiently. Very slow burn but good storyline. 🔥🔥/5

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2. Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.
