Re: stronger exhaust manifold studs?
The 1.5 refers to the thread pitch. We call them course or fine thread, and
sometimes refer to the number of threads per inch, whereas the metrics
typically state what the thread is. I believe it means 1.5mm from thread to
thread. Bottom line - you need 1.5 pitch.
