The Hyundai Elantra and Kia Forte are popular, fuel-efficient compact cars that share powertrains across the Hyundai-Kia platform. Here's what keeps their engines running at their best.
2.0L MPI (Naturally Aspirated)
The base 2.0L engine in the Elantra and Forte uses NGK Laser Iridium or Champion Iridium plugs. This efficient engine is designed for 60,000-mile plug service intervals with iridium. Proper maintenance keeps it delivering its impressive fuel economy numbers.
1.6L Turbocharged GDI (Elantra Sport, Forte GT)
The turbocharged 1.6L direct-injection engine is more demanding. NGK iridium plugs spec'd for GDI turbocharged applications are the right choice. The combination of turbocharging and direct injection creates specific plug requirements — don't use standard copper plugs here.
2.0L Turbocharged (Elantra N)
The performance Elantra N's high-output 2.0T requires iridium plugs with appropriate heat range for boosted applications. Service interval should be shorter than naturally aspirated: 40,000–50,000 miles is prudent.
Value Maintenance
The Elantra and Forte are economy cars — but that doesn't mean cheap parts. The ignition system is just as critical in an economy car as in a performance vehicle. Quality iridium from NGK or Champion is worth every penny.
