The rotor exists to transfer power from your ignition coil to your spark plugs, which ensures that your plugs ignite to start the combustion process. Every time it spins, the metal parts of the rotor come into contact with the central cable of the ignition coil, which is under incredibly high voltage. As soon as it comes into contact with the ignition coil, it transfers electricity to the spark plugs.

Rotors are designed to last for years, but like everything mechanical, they will break sooner or later, and occasional misfires will become a daily occurrence, after which it will be time to replace. If the rotor does not rotate properly, the ignition timing is interrupted, which can cause your car to stall. Your vehicle may also not roll over or start shaking violently.

Here are some precautions when looking for a new rotor:

• Minimize excessive sparkingA: Look for a rotor that minimizes excessive arcing to ensure the rotor lasts longer.

• OEM parts are betterA: OEM parts are best when you're considering distributor rotors. This is because the rotors are specific to your vehicle and some aftermarket parts don't meet the exact specifications you need for a solid fit.

• Brass rotors: Brass rotor contacts do not break easily or corrode as brass is a tensile metal. Brass is also a better conductor of heat and energy than steel.

• Steel rotors: Steel rotor parts resist fatigue longer and are much more durable than brass parts.

• Warranty: check the warranty on whichever type of distributor rotor you choose to make sure you get years of trouble-free service for this expensive part.

No matter what material you choose, make sure you get the best quality possible, as a bad rotor or a badly fitted rotor can wreak havoc on your vehicle's overall performance.
