How to Choose the Best Automotive Replacement Distributor Leads
Installation and Maintenance Tips
When replacing leads, it's often recommended to do so as a complete set. Mark each lead before removal to ensure correct placement. Inspect the distributor cap and rotor for wear or damage, as this can affect lead performance. Clean boots and terminals before reconnecting. Regularly check leads for cracks, burns, or corrosion.
Frequently Asked Questions
What is the difference between copper, carbon, and fiberglass core leads?
Copper core leads offer the lowest resistance for a strong spark but can degrade over time. Carbon core leads provide a balance of performance and durability with moderate resistance. Fiberglass core leads are highly durable and resistant to heat, often used in high-performance applications.
How often should distributor leads be replaced?
Replacement intervals vary by vehicle and lead quality, but a general guideline is every 30,000 to 100,000 miles. Signs of wear like misfires, rough idling, or a check engine light often indicate the need for replacement.
Can I use leads with lower resistance than the original equipment?
For most vehicles, sticking to OE specifications is recommended. While lower resistance can provide a stronger spark, it may also cause radio interference or overload other ignition components if not designed for your specific system.
What does 'OE equivalent' mean for replacement leads?
'OE equivalent' means the replacement part is designed to meet or exceed the performance and specifications of the original equipment installed by the manufacturer.
Do I need special tools to replace distributor leads?
Basic tools like pliers or a dedicated wire puller are often sufficient for removing old leads. Ensure you have appropriate safety gear, as you'll be working with electrical components. Always disconnect the battery before starting.
How do I know if my distributor leads are failing?
Common symptoms of failing leads include engine misfires, rough idling, hesitation during acceleration, reduced fuel economy, and difficulty starting. A check engine light may also illuminate.
