GBTAD Ignition Coil & Iridium Spark Plug Kit — Set of 4 for Hyundai/Kia 2012–2019, Bolt‑In Upgrade, Improved Durability

GBTAD Set of 4 Upgraded Ignition Coil Packs and Iridium Spark Plugs is a bolt-in replacement kit built to restore reliable spark, reduce misfires, and improve throttle response on compatible Hyundai and Kia 4-cylinder engines.

This kit combines four precision-engineered ignition coils with four iridium-tipped spark plugs, designed as a matched set for many Hyundai Elantra, Tucson and Kia Forte, Soul and Rondo 4-cylinder models (2012–2019 model years depending on engine). The components use higher-grade internal materials and improved potting to deliver consistent conductivity and longer service life versus aged OEM units, and they come with manufacturer support for quality issues.

Which vehicles and engines will these coils and plugs fit?

These coil packs and spark plugs are intended for specific 4-cylinder engines across Hyundai and Kia model lines. Fitment depends on year, engine displacement and terminal style — always verify against your vehicle’s OEM part numbers before purchasing.

• Common fits: Hyundai Elantra (2012–2016 L4 1.8L; 2014–2015 L4 2.0L variants), Elantra GT/Coupe and Tucson 2.0L models.
• Kia fits include Forte/Forte Koup/Forte5 (2014–2018 L4 1.8L/2.0L), Soul (2012–2019 2.0L) and Rondo (2014 2.0L).
• Confirm compatibility by year/make/model and OEM part numbers listed in product details before installation.

How do these upgraded coils and iridium plugs affect engine performance?

The kit is engineered to deliver steadier spark energy and improved electrode durability compared with worn factory parts. That can translate into more consistent combustion, reduced misfires and potentially smoother idle and throttle response when installed as a matched set.

• High-conductivity internals and dense epoxy potting reduce energy loss and resist heat cycling.
• Iridium spark tips provide a fine, long-lasting electrode for reliable sparking over longer intervals.
• Designed to address ignition-related symptoms like rough idle, poor fuel economy and check-engine misfire codes.

Are these parts easy to install and which part numbers match OEM references?

Installation is typical for coil-on-plug systems — remove the old coil packs and plug assemblies, then fit the new coils and plugs in their place. The kit lists several OEM cross-reference numbers to help ensure you select the correct replacement for your engine.

• Cross-reference coil part numbers include UF651, 5C1861, C1804, 1788511, 6738305, 273002E000, GN10633.
• Basic hand tools and torque specs for spark plugs are required; replace boots and connectors as needed.
• Refer to vehicle service manual for spark plug gap, torque values and installation sequence.

What quality and after-sales support does the GBTAD kit include?

GBTAD markets these coils and plugs as premium-grade replacements built with aerospace-class conductors and high-density epoxy for improved durability. The manufacturer provides buyer support for quality concerns to address defective units or installation issues.

• Premium-grade copper wiring and reinforced potting for better conductivity and heat resistance.
• Matched coil-and-plug pairing to minimize compatibility issues and optimize ignition timing consistency.
• Customer service available for quality assurance and replacement support if problems arise.

Who is this for: This kit is aimed at DIYers and independent mechanics who need a full set replacement for aging ignition coils and spark plugs on compatible Hyundai and Kia 4-cylinder engines. Choose this set if you want a matched coil-and-plug solution with upgraded internal materials and manufacturer support — but always confirm the fitment against your vehicle’s year, engine code and OEM part numbers before purchase.
