Keep crankcase vapors in check and your intake air clean with the BMS Oil Catch Can Oil Filler Cap Dual Vent Connection Kit for the Gen2 B58. This upgrade ditches the flimsy factory venting in favor of a precision CNC-machined billet oil filler cap and dual-vent fittings engineered to handle increased crankcase pressure under boost. By diverting oil-laden vapors into a catch can instead of back through the intake, this system helps minimize carbon buildup, reduces oily contamination, and promotes more consistent performance as power levels climb. High-quality hoses and fittings ensure a secure, leak-free install that won’t collapse under pressure and maintains a clean, OE-plus appearance in the engine bay. An easy, effective upgrade for B58 enthusiasts looking for cleaner operation, improved engine longevity, and proven performance-focused design

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.

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

The diaphragm is molded from premium, oil-resistant elastomers engineered to withstand prolonged exposure to aggressive synthetic lubricants, fuel vapors, and extreme under-hood heat cycles without losing its elasticity or sealing profile.

Is your BMW making a chirping or grinding noise at idle? The culprit is frequently a failing alternator decoupler pulley. Unlike a traditional solid pulley, this Overrunning Alternator Pulley (OAP) allows the alternator rotor to "freewheel" when engine speeds drop suddenly. This specialized function protects your BMW drive belt and belt tensioner from excessive snap-back, vibration, and "belt slap."

Prevent Catastrophic Engine Failure

Over time, the internal clutch mechanism can seize or slip, leading to accelerated wear or total serpentine belt failure. On BMW engines, a snapped belt can be ingested through the front main seal, causing catastrophic engine damage. Replacing this pulley is a cost-effective preventative maintenance step that restores smoothness to your accessory drive without the high cost of a complete alternator replacement.

Features & Benefits:

Lowers the load on the drive belt, tensioner, and AC compressor.
Stops "belt slap" and rhythmic chirping noises during deceleration and idle.
Direct Replacement with high-quality construction ensures perfect fitment and long-term durability.
Essential Maintenance for N52 engines
