Aerostar AWD V6-183 3.0L (1991)
Distributor: Description and Operation
TFI Octane Rod
Distributor (Typical) - Exploded View
The octane rod adds a provision for a fixed octane adjustment. The adjustment is done by replacing the standard zero-degree rod located in the
distributor bowl with a three degree or six degree retard rod. This is done only if the engine is experiencing a pinging or engine knocking condition and
can not be repaired with the conventional methods (timing adjusted, proper operating temperature, higher gasoline octane rating....etc).
