Temperature Probe Boss - 1/8 NPT Thread for ER B46 Downpipe

Add accurate exhaust temperature monitoring to your B46-powered BMW or MINI with this genuine ER sensor boss upgrade. The 1/8 NPT threaded port comes supplied with a removable blanking plug, so you can run your car now and add a thermocouple later. It is the ideal addition for remapped road cars, dyno tuning, and track use where reliable data and heat management matter.

Why this sensor boss is a smart upgrade

• Dedicated 1/8 NPT threaded take-off for an exhaust temperature probe or gauge sender
• Delivered pre-fitted with a sealing plug for use without a sensor until you are ready
• Enables precise data logging for mapping, calibration, and performance testing
• Helps safeguard turbocharger and engine by monitoring temperatures under load
• Genuine ER component engineered to suit ER B46 downpipes for a precise fit

We have installed this on our own builds and customer cars with excellent results. Owners love the clean integration, easy future-proofing, and the confidence that comes from proper exhaust temperature monitoring during spirited driving and tuning work.
