Our Nissan RB (Twin Cam) Head Drain Adaptors caused quite a stir when we shared the redesign on social media. Surprisingly most of the comments where about function not form.
The design update was the result of our constant improvement process. The new design is aimed at getting the ports clear of the engine block to allow for easier plumbing and keeping overall dimensions to a minimum. The scalloped mounting holes allow the adaptor to be rotated for easy plumbing and flexible mounting and the -8AN rigid extension will protect rubber hoses from rubbing and wearing though where they wrap around the block, as required in other designs, as well as making it easier to plumb.
