OVERVIEW

Whether a 2020+ Toyota GR Supra is bone stock or running an upgraded turbo, the B58 has to breathe. The factory plastic charge pipe between the turbocharger and the intake manifold is adequate for daily driving, but it is a restriction and a known failure point once boost rises. The Mishimoto Performance Charge Pipe Kit replaces it with a free-flowing 3" aluminum assembly.

The kinks and pinched sections of the stock pipe are replaced by smooth mandrel-bent curves, and the couplers and flanges are designed to transition seamlessly from one component to the next. The result is up to 42% less restriction than the factory pipe. Construction is two mandrel-bent aluminum pipes with precision CNC-machined adapters for durability and exact fitment, and two pre-installed bungs can be drilled and tapped for boost sensors, nitrous or methanol injection.

The supplied coupler is built from five layers of silicone with embedded heat-resistant fibers and steel wire reinforcement to prevent ballooning under high boost pressure, and constant-tension worm gear clamps are included. The kit is a direct fit with no other modifications required and carries the Mishimoto Lifetime Warranty.
