I am not used the product yet so I cannot give you a rating or otherwise it's a product sucks I will tell you it sucks

The coil packs were just as expected. They were perfect fit and packaged well. My only concern is the green dielectric grease that was proactively put onto the coil packs at the factory dried out and cracked. I would suggest putting a little packet someone can open just as o'rielys or auto parts has for the individual to add upon the time of installation.
Thanks for the thoughtful feedback, Mavrick! We’re glad to hear the coil packs fit perfectly and arrived safely—your suggestion about some fresh dielectric grease packets really makes sense and is something we’ll look into to improve the overall experience.
Very satisfied, received as promised, filling out this survey requesting over 50 characters just to submit is ridiculous. Let me put in there what I want to put but as many character as less character that I wanna put in there.

I would not buy any thing from company price are so so but this is where it gets back when you return a item and should get a refund on it they will never give you your refund or answer you messages so to make a long story short l would definitely not recommend this company
Hi Jeffrey, I’m sorry to hear about your experience with the refund process and lack of communication. Upon further review we see that your first message was received on 08/07 and you were advised to contact us once you see that your return has been delivered to expedite your refund. You messaged again on 08/10 which unfortunately is outside of our normal business hours, Your last message was received yesterday 08/12 and we responded this morning with a refund back to your credit card. We will send you a refund receipt in a separate message.
First time with this company so far everything went great very happy
Sixity had the part I needed at a reasonable price. Their use of Amazon shipping was my only complaint. So my Shepherd barked at them and they didn't deliver until the following day calling it pet interference. Obviously not sixity's fault and they handled it well.
Thank you, Robert, for your kind words and your sense of humor about the shipping hiccup! We’re glad we could provide the right part at a fair price and appreciate your understanding.
I would recommend this company to anyone. Pricing was good and shipping time was within reasonable limits.
Thank you, Kael, for your kind words and recommendation. We truly appreciate your support and are committed to providing great service and value every time. We look forward to assisting you again soon!
The range are about 5000 ohm but your NGK sparkplugs are 4790 ohm for the lowest and the high is 5030. It should be between 0-200 ohm for all plugs.
Skeptical at first because of low prices but multiple orders and many parts later I have zero complaints and my vehicles are running smooth.
Thanks so much for giving us a chance even with some initial doubts, J. We're thrilled to hear your vehicles are running smoothly, and we truly appreciate your continued trust and support!
