Service Overview
Comprehensive Ignition System Guide
The ignition system is responsible for the precise timing and delivery of the electrical spark needed to ignite the air-fuel mixture in your engine. When this system is operating at its peak, your vehicle delivers smooth acceleration, optimal fuel economy, and reliable starts. However, because components like spark plugs and ignition coils are subjected to thousands of high-voltage pulses every minute, regular Ignition System Services are essential for maintaining engine health. At Owl-Let, we specialize in the technical diagnostics required to keep your combustion cycle perfect.

View All Service LocationsFrequently Asked Questions
How often should I schedule Ignition System Services?
While many modern iridium spark plugs can last 100,000 miles, Owl-Let recommends an ignition system inspection every 30,000 miles. Factors like stop-and-go driving or using lower-grade fuel can necessitate more frequent Ignition System Services.
Can faulty spark plugs cause my car not to start?
Yes. If the spark plugs are severely fouled or worn, they may not be able to generate a strong enough spark to ignite the fuel, especially in cold weather. Professional Ignition System Services ensure your vehicle starts reliably every time.
What is an engine misfire, and why is it dangerous?
A misfire occurs when the ignition system fails to ignite the air-fuel mixture in a cylinder. This causes the engine to run out of balance and can lead to raw fuel entering the exhaust system. Owl-Let treats misfires as an urgent part of our Ignition System Services.
Is it necessary to replace all ignition coils at once?
Not always. While it is often recommended to replace spark plugs as a set, ignition coils can be replaced individually as they fail. During your Ignition System Services, we will test each coil to determine which ones are still within operating parameters.
