Take your B58 or S58 build further with the JB4PRO Flex Fuel Add-On Harness—a simple, plug-and-play way to add an ethanol sensor and optional fuel pressure sensor to your JB4PRO setup. Keep your install clean, your wiring organized, and your tune dialed to match every fuel blend in the tank. Why it matters: Plug & Play: Connects directly to your JB4PRO—no cutting or splicing required. Sensor Ready: Supports ethanol and fuel pressure sensors for precise, real-time fueling adjustments. Clean, Safe Installation: Includes a 12 V adapter and inline fuse for hassle-free integration. How it works: This harness links your JB4PRO tuner to your flex fuel hardware. It’s not a complete flex fuel kit—you still need a compatible ethanol sensor—but it gives your JB4PRO the accurate readings it needs to adjust timing, boost, and fueling for E30, E50, or E85 blends.

Keep heat where it belongs and boost where it counts with a B58 Turbo & Intake Heat Shield for BMW and Toyota Supra—an OE-plus style upgrade that helps your setup stay cooler, more consistent, and happier when you’re leaning on it. BMW’s factory heat management is fine at stock-ish levels, but once you start turning the wick up, the turbo becomes a rolling space heater. That radiant heat soaks the nearby intake tract, nudging IATs up and making performance less repeatable pull after pull. This shield steps in as a dedicated barrier between the turbo and intake components, helping reduce heat soak so you can keep intake air cooler and denser when you’re driving it like you mean it. Built with a clean, factory-inspired mindset, it’s precision-formed to wrap neatly around the B58 turbo and intake area, and it mounts using factory locations for a tidy, OEM-level install. No cutting, no permanent changes, and fully reversible—just a straightforward bolt-on that looks right at home in the engine bay. Made from durable, heat-resistant materials, it’s designed to handle the heat long-term without turning into a crispy science project. Why it matters Cuts down radiant heat from the turbocharger into the intake area Helps reduce intake air temperature creep Improves consistency during repeated pulls and hard driving Adds protection for surrounding components exposed to turbo heat Features & highlights Designed for BMW B58 and Toyota Supra applications Precision-formed for OEM-level fitment Heat-resistant construction for long-term durability Bolt-on install using factory mounting points Clean, OE-plus under-hood appearance
