Route spark energy to every cylinder with the Standard Ignition Distributor Cap MA-409. It is a replacement distributor cap for the 1970-1973 Fiat 850 and 1971-1973 Fiat 128. Engine details for each application are in the "Vehicles it fits" section.
The distributor cap carries high-voltage current from the ignition coil, through the spinning rotor, to each spark plug wire terminal in firing order. Standard Ignition draws on decades of research and development in its distributor caps and rotors. Its caps offer the following:
- Quality control throughout: Standard Ignition is a global manufacturer of original equipment ignition products and oversees quality at every stage, from individual components to the finished product.
- High dielectric strength housing: Standard Ignition makes its distributor caps from glass/mineral reinforced polyester resin for less carbon tracking and greater resistance to electrical breakdown.
- RFI resistors where specified: These are designed to help suppress radio static and potentially damaging voltage spikes.
- Solid brass terminals (where available): These are intended to make better connections and resist electrical pitting and corrosion.
Signs that a distributor cap may need replacing include cracks in the cap, carbon tracks or corroded terminals inside it, misfires, rough running, and hard starting. These symptoms can have other causes, so diagnose the ignition system before you replace parts.

Frequently Asked Questions
What does a distributor cap do?
It carries high-voltage current from the ignition coil, through the rotor, to each spark plug wire terminal so every cylinder receives spark in firing order.
Which vehicles does the Standard Ignition MA-409 fit?
It is listed for the 1970-1973 Fiat 850 and the 1971-1973 Fiat 128. See the "Vehicles it fits" section for engine details.
What material is the cap made of?
Standard Ignition makes its distributor caps from high dielectric strength, glass/mineral reinforced polyester resin for less carbon tracking and greater resistance to electrical breakdown.
Does it use brass terminals and an RFI resistor?
Standard Ignition uses solid brass terminals where available and RFI resistors where specified for the application. The resistors are designed to help suppress radio static.
What are signs of a failing distributor cap?
Cracks, carbon tracking, corroded terminals, misfires, rough running, or hard starting may point to a worn cap. These can have other causes, so diagnose the ignition system before you replace parts.
