CarBole Iridium Spark Plug and Ignition Coils, Replacement for Nissan Maxima Altima Xterra Frontier, Infiniti QX4 I35, Suzuki Equator 3.0L 3.5L 4.0L V6, (OE: UF349, 5018)

Amazing customer service!! Happened to get a misfire on a cylinder. A replacement was sent right away! The coil packs and plugs are very well made. I recommend this product!

Update: company reached out and resolved the issue and replaced the faulty items, for shipment was faulty and they stood by their product and made it right, great costumer serviceThe ignition coils started causing idling problems on my car, also would put my car in limp mode leaving me stranded more than a few times, after many trips to the mechanic shop fixing different issues that could be causing my car to stall i decided to replace the ignition coils with the originals and the car started working perfectly, the sparkplugs included were the only good thing from this package

Two of the six ignition coils misfired immediately, and my mechanic reinstalled the two from the set he had just replaced. I ordered another set from a different brand. (Ref Order # 114.....3448 of October 20.) Unfortunately, I won't be within the 30-day return period by the time I receive the new set and have it installed. I would still like consideration be given to refund me.

Was skeptical with this at first... But decided to give it a try. All work fine no problems at all.And the vehicle and plugs were put into good testing (racing car) no misfires or codes or errors.If any problems in the future, can update the review, but so far so good. Great price. Thank you!

I've had them on my xterra for over a month now and it's been great 👍 big difference.
