Advance Spring Set (2) 1976-78
Over time, the advance springs weaken and no longer do they properly retract the advance mechanism. This can result in a slightly advanced ignition timing at idle. The symptoms are a slower than desired return to idle or a high idle. We recommend replacing these springs when replacing the points.
Sold as a set of two. Equivalent to BMW Part Number 12 11 1 357 627, but at almost half the price.
