The spark plug model for the Elantra is RC10YC4. If you prefer platinum spark plugs, you can choose NGK6809 or NGK5787. The spark plugs in a car need to be replaced regularly to maintain optimal performance. Spark plugs, commonly known as sparkers, function by discharging high-voltage pulses sent through the high-tension leads, creating an electric spark that ignites the air-fuel mixture in the cylinder by breaking down the air between the two electrodes. The Elantra is a model produced by Beijing Hyundai. In terms of dimensions, the Elantra measures 4542mm in length, 1775mm in width, and 1490mm in height, with a wheelbase of 2650mm. The interior of the Elantra successfully creates a youthful atmosphere, featuring a more streamlined dashboard design. The blue backlighting on the instrument panel and dashboard also looks particularly striking at night.
The Hyundai Elantra comes with standard nickel alloy spark plugs from the factory, but the specific model depends on the vehicle year. When I replaced the spark plugs on my 2011 Elantra, I checked the manual and found the original ones were NGK BKR5EIX-11. Later during maintenance at the repair shop, the mechanic suggested platinum or iridium plugs for longer lifespan. Now I'm using NGK platinum plugs, which have run smoothly for 40,000 kilometers. When replacing spark plugs, it's crucial to match the heat range. My suggestion is either follow the factory standard or upgrade to double platinum plugs. If purchasing yourself, remember to provide the exact model year to avoid getting incompatible spark plugs.
The most important thing when choosing spark plugs for the Elantra is to check the engine model. The older Gamma 1.6L can use ordinary nickel alloy ones, while the newer Nu series 1.6L engine is recommended to use platinum ones. Last time I met a mechanic at the auto parts market who said the original NGK BKR5EIX can last 30,000 to 40,000 kilometers, but if you frequently drive on highways, you can switch to NGK's LFR5AIX iridium-platinum model. Pay attention to gap adjustment during installation, around 0.8 mm is ideal—too wide or too narrow affects ignition. As for price, ordinary ones cost 30-50 yuan each, while iridium ones are more expensive but much more durable.
The selection of spark plugs for Hyundai Elantra mainly depends on the material, which I've researched. Nickel alloy is the cheapest but has a short lifespan, while iridium is the most expensive and can last up to 80,000 kilometers. Platinum falls between the two. The maintenance manual specifies the original heat range of 5-6 and a gap of 0.7-0.8 mm. Currently, the commonly used ones in the market are NGK's BKR5E and DENSO's FK20HR11. For newer models, the ILKR7B iridium type can be used. When replacing, remind the mechanic not to overtighten, as the aluminum cylinder head is prone to thread stripping. Cars experiencing weak cold/hot starts or acceleration should have their spark plugs checked.
