Specs At A Glance

Good To Know

Q: What is the purpose of limiting mechanical advance? A: Restricting the advance allows you to run more initial timing at idle for better response while keeping total timing at a safe limit under load.

Q: Do I need special tools to change these limiter bushings? A: Installing these bushings requires removing the distributor cap and rotor, making the swap straightforward with basic hand tools.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
