Product Details

The Dorman 86579 In-Line Spark Checker is an essential diagnostic tool for quickly identifying ignition system problems. This universal tester connects inline between the spark plug and plug wire to check for faulty spark plugs and weak ignition wires without removing components from the engine.

Key Features:

  • Visual spark indication through light frequency and intensity
  • Inline design allows testing while engine is running
  • Universal fit works with most spark plug applications
  • Helps diagnose misfires, weak ignition, and plug wire issues
  • Simple installation between plug wire boot and spark plug
  • Durable construction for professional and DIY use

The brightness and flashing pattern of the indicator light reveals the strength and consistency of the spark, making it easy to pinpoint ignition problems. An ideal troubleshooting tool for automotive, small engine, and powersports applications.

Great will buy from again *+++++

Autoplicity was an easy and simple transaction! It is appreciated when an online retailer is responsive to customer's needs. I contact Autopilicity over the phone on several occasions and was promptly greeted with a professional Customer Service representative that was immediately capable of answering my questions and concerns. Thank you Autopilicty and keep up the great work!

Great service and products for the price. Searched for the part all over and autoplicity beat every one else price. Very fast shipping.

Price is about on par with everyone else. But excited to get it in 2 days hopefully

SHIPPING FOR SUCH A SMALL ITEM IS MORE THAN THE ITEM ITSELF, THATS JUST WRONG!

Easy website site to navigate

The service and product was excellent!

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

fine so far

Great prices for the springs I got. Def. the cheapest around! Everything was fast and straight forward.

I have searched the internet for the best pricing on auto accessories and ended up at Autoplicity. I tried everything to negotiate prices with some supplies and still got the best pricing usins Autoplicity without any hassles or delays. My invoice number 9314 shows that I got a great deal thanks to Autoplicity. I will be a returning customer for my future purchases.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

Great Price!

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
