I am pleased with the quality and value. The parts were in perfect condition when received. No problem installing any of the parts. Beautiful finish on the ignition coils. Spark plugs were clean with a good threads on the ground point. My car is running better now. I would say much better if we didn't find oil in the 3rd and 4th cylinders. My car still starts on the 1st turn. I would definitely buy the kit again if I have a car that uses them. If I don't I will definitely consider buying whatever ones I need from the manufacturer. I haven't had any issues with the parts in the 24 hours they have been installed. Thumbs up for this purchase!

Perfectly packaged and great performance.

Part fit correctly. No error codes

This is the perfect inexpensive kit u can get my check engine light was on I needed a tune up bought this installed it no issues

2012 Transit Connect, 100 miles a day minimum. Perfect, NO plug issues I was not trying to rectify any serious issues. Having solved all vibration issues with new struts and CV axles. I could feel some vibration 0 - 40 mph. After consulting AI, poor preforming ignition coils could contribute to “Engine Shudder” at low speeds. So the price was just to low to pass up. Problem fixed, the minute I fired up the engine i could tell it was smoother. What I learned was that coils can operate poorly, not just fail. I drive my vehicles for a lone time and do a lot of preventive maintenance.
