Improved Advance Curve Service: Bosch “002” Distributor

Product Description:

Improved Advance Curve for Bosch® 0.231.159.002
During restoration, we’ll also improve your advance curve.
Offered ONLY when we are also restoring your dstributor.
See our part number 901.602.021.ZX for the restoration service.

The factory advance curve on the Yellow Tag distributor is often suboptimal for the 911S engine it was fitted to. The advance kicks in too early, which can cause roughness, belching, etc. at lower RPMs. Due to manufacturing variations in the advance weights 50+ years ago, some yellow tag distributors cause a more pronounced roughness than others.

This recurve will keep the advance at zero further into the RPM range, which is a better fit for the S engine. You will receive a print-out of your distributor’s new advance curve. This recurve involves additional labor and machining beyond our regular restoration service, so we offer it as an optional upgrade to our standard service.

The recurve is only available if we are also restoring your distributor. Please send in your well packed distributor with your online order number on the outside of the box, to:
