How Often Should You Replace Ignition System Components?

Maintain your car’s performance by replacing ignition system components like spark plugs (every 30,000–100,000 miles), ignition coils (when faulty, typically 100,000 miles), and ignition switches (if failing). This guide covers intervals, factors, and MAPMS’s high-quality parts for longevity.

Introduction

Regular replacement of ignition system components is crucial for maintaining your vehicle’s performance. Knowing when to replace spark plugs, ignition coils, and other parts can prevent issues and save money. This guide outlines replacement intervals and the importance of quality parts from MAPMS.

Replacement Intervals

• Spark Plugs: Replace every 30,000–100,000 miles, depending on type (copper: 20,000–30,000; platinum/iridium: 60,000–100,000+).

• Ignition Coils: Typically last 100,000 miles but replace if faulty to avoid misfires or starting issues.

• Ignition Switch: Replace only when failing, often lasting the vehicle’s lifetime with proper care.

Factors Affecting Replacement

• Driving Conditions: Harsh conditions (e.g., extreme temperatures, stop-and-go traffic) may require earlier replacement.

• Vehicle Type: High-performance engines may need more frequent maintenance due to increased stress on components.

• Part Quality: High-quality parts last longer and perform better, reducing the need for frequent replacements.
