Product description

Can I just replace one coil, or should I replace all?

We highly recommend replacing all coils and spark plugs as a set for balanced performance and to prevent future issues.

Does this fit my 2016 Hyundai Sonata 2.4L?

Yes, this does. Please double-check your vehicle trim and engine size using the Amazon fitment tool above before ordering.

Are these better than the original/OEM parts?

Autoexact's Ignition Coil Kit is a direct OE replacement with key upgrades: Iridium spark plugs offer superior ignition performance and longer service life, ignition coils built with high-temp materials and epoxy potting for stability and longevity.

Will this improve my gas mileage and performance, and do I need to gap these spark plugs?

Yes, boosts mpg & performance—Autoexact’s kit delivers stronger spark for full combustion, better acceleration/throttle response. Iridium plugs pre-gapped (ready to install out of box). Don’t adjust gap—avoids fine-wire electrode damage.

What should I do if there is a problem after purchasing the spark plugs and coil packs kit?

Autoexact offer a 24-month replacement for any quality issues. If you experience a manufacturing defect, please get in touch with us for a replacement. Your satisfaction is our goal.
