Why Replace Spark Plug Wires?
Spark plug wires transfer high-voltage current from the ignition coil and distributor to each spark plug. As insulation ages, resistance increases and voltage leakage becomes more common.
Common symptoms of failing ignition wires include:
- Rough idle
- Engine hesitation
- Hard starting
- Poor acceleration
- Reduced fuel economy
- Check Engine Light
- Engine misfires
Replacing worn wires restores proper spark energy and helps maintain efficient combustion.

Frequently Asked Questions
How often should Honda spark plug wires be replaced?
Most ignition wires should be inspected during every tune-up and are commonly replaced between 60,000 and 100,000 miles, depending on age and operating conditions.
Can bad spark plug wires cause a rough idle?
Yes. Aging ignition wires can leak voltage or develop excessive resistance, leading to rough idle, hesitation, and engine misfires.
Is this a direct replacement?
Yes. The ST-4174 is designed as a direct-fit replacement using OEM-style boots and terminals for compatible Honda Accord and Prelude applications.
Should spark plugs be replaced at the same time?
Yes. Replacing spark plugs and ignition wires together restores the complete ignition system and often delivers the best long-term reliability.
