N52 Rear Head Vent

Running your N52 swap hard on track? As you already know, these engines can run hot.

May also fit other N5X and S5X engines- Reach out if you are interested

This fitting allows you to vent the rear of the cylinder head to the cooling reservoir, bleeding off trapped air and steam caused by localized boiling. By continuously purging bubbles from the highest point in the head, it helps reduce hot spots, stabilize coolant temps, and improve overall cooling efficiency.

This exact strategy has been used on race engines for decades and is now easily applied to your N52.

Details:

• Thread: M10 × 1
