One thing I recently did on my old Yamaha that greatly improved its performance was replacing the 30 year old spark plug wires. They have a resister in the cap that breaks down over time.
Is the situation with older BMWs the same? Is it good practice or a waste of money to replace spark plug wires before they flat out fail?
