Ignition Cassette
An ignition cassette is a housing that holds the ignition coils for one bank of cylinders and sends spark straight to the plugs. We list 1 ignition cassette at $280, an AC Delco part for the 2001 Oldsmobile Aurora, listed for the right side position.
What an ignition cassette does
Some GM engines use a cassette that mounts the coils and their control electronics in one unit. On a V8, there can be one cassette per bank, which is why this part is listed by side.
The cassette replaces the separate distributor, cap and rotor used on older engines. It fires each coil when the engine computer signals it. It is sold as a single unit for the listed side.
Signs of a problem
A failing cassette or one of its coils can cause misfires on one bank, a rough idle, hesitation, a flashing check engine light and misfire codes for the cylinders on that side. Cracks in the housing or carbon tracks can also leak spark.
Check the spark plugs and plug boots first, since worn plugs put extra strain on the coils. A scan tool helps show which cylinders are misfiring.
Fitting tips
This part is listed for the right side position on the 2001 Oldsmobile Aurora. Confirm your engine and the side in the fitment table, and compare the part number on your old cassette before ordering.
Disconnect the battery before removing the cassette. Replace worn plug boots, check the connector for corrosion, and torque the mounting bolts evenly. Clear stored codes after the repair and confirm the misfire is gone.
Ignition Cassette questions
What vehicle does this ignition cassette fit?
The cassette listed here is an AC Delco part for the 2001 Oldsmobile Aurora, in the right side position. Check the fitment table to confirm your engine.
How do I know if my ignition cassette is bad?
Misfire codes on cylinders from one bank, a rough idle and loss of power are common signs. Rule out spark plugs and boots before replacing the cassette.
Should I change spark plugs with an ignition cassette?
It is a good idea if the plugs are old. Worn plugs need more voltage to fire, which adds strain on the coils in the new cassette.
