- Voltage Range: I found it essential to select a tester that covers a wide voltage range. Most coils operate between 12V and 25V, so I made sure my tester could handle this range.
- Durability: Since I often work in less-than-ideal conditions, I opted for a pen made from sturdy materials. A strong casing can withstand drops and exposure to engine heat.
- Ease of Use: I preferred a pen that was straightforward and user-friendly. Features like a bright LED display or audible alerts made it easy for me to read results quickly.

- Advanced Diagnostic Tools: If you’re a professional mechanic or a serious DIYer, investing in a high-end diagnostic tool might be worth it. These models often provide extensive vehicle data and can test multiple components.
Price Range
When I was comparing prices, I noticed that ignition coil tester pens come in various price ranges. Basic models can start as low as $10, while advanced options can go over $100. I recommend establishing a budget based on how often you’ll use the tool and the features you need. For occasional use, a mid-range option typically suffices.

I always check brand reputation before making a purchase. Brands like Innova, Actron, and OTC are well-known for their quality automotive tools. Reading user reviews helped me gauge the reliability and effectiveness of different models.
Where to Buy
I found that ignition coil tester pens are available both online and in local auto parts stores. Online marketplaces like Amazon, eBay, or specialized automotive tool retailers often have a wider selection and competitive prices. However, visiting a local store allows you to see the tool firsthand and ask staff for recommendations.
