Product Details

The SG Tool Aid 23920 In-Line Spark Checker features a 90-degree boot design with an extended wire for easy installation and removal between the spark plug and ignition wire. This diagnostic tool allows technicians to visually inspect the ignition system at each cylinder while the engine is running, with the frequency and intensity of the visible spark flash indicating whether issues stem from the ignition system or fuel delivery system.

Key Features:

  • 90-degree boot design ideal for confined engine compartments and tight access areas
  • Longer wire provides flexibility when working around obstructions like shock towers, A/C lines, and exhaust headers
  • Hands-free operation allows quick ignition system troubleshooting
  • Bright flash visible even in direct sunlight for easy diagnostics
  • Clear plastic body withstands rough shop use and resists automotive chemicals
  • Protected by mechanical strain relief for extended durability
  • Shows duplicate view of ignition spark for accurate system analysis

Perfect for diagnosing misfires, weak spark conditions, and ignition system faults on modern vehicles with limited engine bay access. The rugged construction and chemical-resistant materials ensure reliable performance in professional automotive shop environments.

This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

Best price fast shipping. will deffinitly order again

Good

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

So far so good

Only downside is I couldn't use multiple coupons - one for shipping discount and another for 10% off.

So far so good

Could not pay with Pay Pal even though you show that option

Good product, great price, will do business again.

Ordering is quick and easy and product was just as described

Went smoothly

Good price just hope it's not too good to be true. Here's to hoping.

I ordered the part from Autoplicity and it arrived in time and is a great product<br>
