MIKKUPPA Ignition Coil and Spark Plug Set UF651

When an ignition coil or spark plug needs replacing, matching the parts to the vehicle and engine matters as much as getting a complete set. This MIKKUPPA package pairs four UF651 ignition coils with four 9686 iridium spark plugs, giving you both components for a listed Hyundai or Kia application in one purchase.

Its appeal is practical: the coils and plugs are sold together rather than requiring a separate search for each part. The main decision is whether your exact vehicle and engine are included.

Key points

The package includes four ignition coils and four iridium spark plugs. The coils are listed under UF651 and several alternate replacement numbers, while the spark plugs are identified as 9686. The description says the coils use copper cores for conductivity and an epoxy-and-reinforced-plastic exterior intended to withstand engine heat. Those are design claims, not a guarantee of a particular change in fuel economy or engine performance.

A set can simplify a repair when you intend to replace all four coils and plugs together. If you only need one component, or your repair calls for a different quantity, buying the bundled set may not be the most suitable approach. Keep in mind that the long vehicle list does not replace checking the exact year, engine, and part number for your car before ordering.

Fit and sizing

Listed Hyundai applications include the 2012–2016 Elantra 1.8L, 2013–2020 Elantra GT 2.0L, 2013–2014 Elantra Coupe 2.0L, and 2014–2020 Tucson 2.0L. Kia applications include the 2014–2015 Forte Koup 2.0L, 2014–2016 Forte 1.8L, 2014–2018 Forte5 2.0L, 2017 Forte Koup 2.0L, and 2012–2019 Soul 2.0L. The product also names UF764, UF611, and UF652 as additional Hyundai replacement references, so don't treat those numbers alone as confirmation of fit.

Before buying, compare your vehicle's details with the listed application and replacement numbers. A Tucson year may look like a match, for example, but the engine specification still matters. If your vehicle or engine isn't listed, the supplied information isn't enough to confirm compatibility.

Tips for day-to-day use

For a planned tune-up, check whether your repair requires replacing all four coils and plugs or only the parts that have failed. This set is most straightforward when the job calls for four of each: you can keep the matching components together and avoid sourcing plugs separately. If you're diagnosing a rough-running engine, remember that the listing doesn't establish that worn ignition parts are the cause, so confirm the fault before treating a full set as the fix.

The seller states that the coils are heat- and pressure-tested and includes a one-year warranty. Those details may matter when comparing a bundled aftermarket set with buying only the specific replacement part you need, warranty coverage terms beyond the stated duration aren't provided here.

Questions before you buy

What comes in the package? Four ignition coils and four 9686 iridium spark plugs.

Which replacement numbers are listed? The coils include UF651, 5C1861, C1804, 273002E000, 1788511, 6738305, and GN10633. The plugs are listed as 9686.

Is a warranty included? The product description states a one-year warranty, but doesn't give further coverage details.

Is it worth it?

A solid pick if your listed Hyundai or Kia application needs four coils and four plugs, and you want both parts in one package. From the way it is set up, it suits a planned multi-part replacement better than a repair that only calls for one coil or a different plug reference. You may want to skip it if your exact engine and year aren't on the fitment list or you can't match the replacement numbers, the listing doesn't establish compatibility beyond the applications it names.
