Description
Mishimoto’s MMICP-SUP-20BK is a purpose-built aluminum charge pipe engineered to replace the fragile factory plastic charge pipe fitted between the turbocharger and intake manifold on B58-equipped vehicles. Built from two mandrel-bent aluminum sections with CNC-machined flanges, this Forced Induction upgrade eliminates the kinks and pinched sections that restrict airflow in the stock design, delivering up to 42-percent more flow than the factory plastic pipe it replaces.
Whether you’re refining your induction system for daily driving or building toward a more aggressive forced induction setup, this Mishimoto charge pipe kit is designed to handle real boost. The smooth-flowing 3-inch piping and seamlessly transitioning couplers and flanges reduce turbulence for a more efficient path from turbo to intake manifold, supporting stronger forced induction performance. Two pre-installed bungs let you drill and tap for boost pressure sensors, nitrous, or methanol injection, adding flexibility for performance induction builds. The included silicone coupler is made from five layers of material with embedded heat-resistant fibers and steel wire reinforcement so it resists ballooning as boost pressure climbs, and constant-tension worm gear clamps are included for a secure, lasting installation. The two-piece design keeps the swap straightforward, and the pipe is backed by Mishimoto’s lifetime warranty.
Vehicle Applications
This charge pipe is engineered around the B58 engine (chassis codes A90 and GR) and is a direct fit for 2020+ Toyota Supra 3.0L models. Within the GR Supra range, that covers the Base and Premium trims from 2020 through 2023, the 2020 Launch Edition, the 2021–2022 A91 Edition, the 2023 A91-MT Edition, the 2024 45th Anniversary Edition and Premium 45th Anniversary Edition, and the 2024–2025 Special Edition, along with the 2021 Supra Azul and Supra GR trims. Because BMW also builds the B58 engine, this same charge pipe fits a broad range of BMW models: the 2020 540i Base and M Sport plus the 2020–2025 540i xDrive Base; the 2020–2022 740i Base, 740i xDrive Base, and 745e xDrive Base along with the 2020 740i Excellence; the 2020–2025 840i Base, 840i Gran Coupe Base, 840i xDrive Base, and 840i xDrive Gran Coupe Base; the 2020–2021 M340i Base, the 2020 M340i xDrive First Edition, and the 2020–2025 M340i xDrive Base; the X3 lineup, including the 2020–2024 M, M Competition, M40i, sDrive30i, xDrive30e, and xDrive30i, the 2025 30 xDrive, M50i, and xDrive30, the 2021 sDrive20i, the 2020 sDrive20i Executive, the 2020–2021 xDrive30i Protection, and the 2020 xDrive30i X Line; the X4 lineup spanning 2020–2025 for the M, M Competition, M40i, and xDrive30i, plus the 2020 xDrive30i Executive and X Line; the X6 lineup covering the 2020–2023 M, M Competition, and M50i, the 2020–2025 xDrive40i, the 2020–2021 sDrive40i, and the 2020 xDrive40i M Sport; and the Z4 lineup with the 2019–2022 M40i, the 2020–2021 M40i First Edition and sDrive M40i, the 2021–2023 sDrive20i, the 2019–2020 sDrive20i M Sport and Sport Line, and the 2019–2023 sDrive30i.
