Keep high-voltage spark moving to every cylinder in firing order with the Standard Ignition Distributor Rotor MA-307. It is a direct-fit replacement for many vehicles, among them the 1968-1983 Fiat 124, 1978-1981 Fiat Brava and 1979-1980 Fiat Strada. See the "Vehicles it fits" section for the full list and engine details on each application.
The rotor turns with the distributor shaft beneath the cap and passes coil voltage to each spark plug terminal in sequence. Standard Ignition is a global manufacturer of original equipment ignition products. It maintains quality control across the whole manufacturing process, from componentry to the finished product.
- High-grade dielectric strength alkyd: resists dirt sticking, which decreases carbon tracking for extended service life.
- Solid brass segments: provide better conductivity and higher-voltage spark to the plugs.
- Shaft retention clips: used where required for proper fit and performance.
- Research and development: draws on decades of Standard Ignition research and development in distributor caps and rotors.
Signs that a distributor rotor may need replacing include engine misfire, hard starting, rough running, and a rotor tip that is burned, worn or cracked. If a worn rotor is the cause, MA-307 replaces it. Inspect the distributor cap at the same time.

Frequently Asked Questions
What does a distributor rotor do?
The rotor turns with the distributor shaft beneath the cap and passes high voltage from the coil to each spark plug terminal in the cap, in firing order.
Which vehicles does the Standard Ignition MA-307 fit?
It is listed for many vehicles, among them the 1968-1983 Fiat 124, 1978-1981 Fiat Brava and 1979-1980 Fiat Strada. See the "Vehicles it fits" section for the full list and engine details.
What are the rotor's segments made of?
Standard Ignition distributor rotors use solid brass segments. The manufacturer states these provide better conductivity and higher-voltage spark to the plugs.
How does the alkyd material help?
The high-grade dielectric strength alkyd resists dirt sticking. This decreases carbon tracking and helps extend service life.
What signs mean the rotor may need replacing?
Misfires, hard starting, rough running, or a burned, worn or cracked rotor tip can indicate a failing rotor. Diagnose first, because the cap, wires or coil can cause similar symptoms.
