NGK LKR7BIX Iridium Spark Plug – OEM Replacement for Hyundai 1.2L Kappa, Tata 1.2L Revotron & Maruti Suzuki 1.2L K-Series Engines
The NGK LKR7BIX Iridium Spark Plug is an OEM-spec ignition component designed for select 1.2-litre petrol engines used across Hyundai, Tata, and Maruti Suzuki passenger vehicles, where the LKR7BIX spark plug specification is recommended. Manufactured to NGK's established iridium spark plug standards, this model is intended to provide consistent ignition performance and reliable combustion under normal driving conditions.
Spark plugs play a critical role in petrol engines by igniting the air-fuel mixture inside the combustion chamber. A stable and consistent spark helps ensure smooth engine operation, dependable starting, and controlled combustion. The NGK LKR7BIX is built to meet these requirements when installed in engines that specify this exact plug code.
Iridium Spark Plug Construction
Iridium spark plugs use a fine-wire iridium centre electrode, a material selected by NGK for its high melting point and resistance to electrode wear. Compared to conventional copper spark plugs, iridium electrodes maintain their shape and spark characteristics over longer operating periods. This helps the spark plug continue to perform consistently across repeated heat cycles and extended use.
The fine-wire electrode design allows the spark to form more precisely at the tip of the electrode. This contributes to stable ignition without requiring changes to engine tuning or fuel delivery. The NGK LKR7BIX is designed as a like-for-like replacement component, not as a modification that alters engine behaviour.
In addition to the iridium centre electrode, the spark plug features NGK's ceramic insulator and plated metal shell. These components are designed to support electrical insulation, manage heat dissipation, and provide durability during routine installation and removal.
Intended Application
The LKR7BIX spark plug is commonly specified for Hyundai Kappa 1.2L (2nd generation) petrol engines, Tata 1.2L Revotron petrol engines, and Maruti Suzuki's 1.2L K-Series petrol engines. It functions as a direct replacement only when the vehicle manufacturer or service documentation specifies LKR7BIX or LKR7BIX-P.
This spark plug does not change engine mapping, compression, or output. Its purpose is to maintain proper ignition performance and combustion stability in engines designed for this specification.

Compatibility applies only where LKR7BIX is the specified spark plug code for your exact engine and model year. Vehicles using a different spark plug specification should not use this model. As fitment can vary by production date and trim, please cross-check your vehicle's owner manual or NGK's official application chart, or reach out to us, before ordering.
Replacement & Use Considerations
Spark plugs are service components and should be replaced according to the vehicle manufacturer's recommended service intervals. While iridium spark plugs are designed for longer service life compared to conventional plugs, actual replacement timing depends on engine condition, driving environment, fuel quality, and maintenance practices.
The NGK LKR7BIX is supplied as a single spark plug. Vehicles may require multiple spark plugs depending on engine design. Buyers should confirm the quantity required for their specific engine before purchase.This listing price is for one spark plug only.
Installation should be carried out following standard service procedures, including correct tightening torque and clean thread conditions. Improper installation may affect performance or cause damage.
Summary
The NGK LKR7BIX Iridium Spark Plug is a high-quality, OEM-spec ignition component intended for select 1.2-litre petrol engines used by Hyundai, Tata, and Maruti Suzuki. Built with an iridium fine-wire centre electrode and NGK's proven construction standards, it is designed to provide stable ignition and reliable combustion when used in engines that specify the LKR7BIX code.
As with all ignition components, correct application and compatibility verification are essential before installation.
OEM Specification & Service Context
The NGK LKR7BIX iridium spark plug is manufactured to meet OEM replacement requirements where this specific plug code is specified by the vehicle manufacturer. NGK assigns spark plug codes based on critical parameters such as thread size, reach, heat range, terminal type, and electrode configuration. Using the correct spark plug code is essential to ensure proper fitment and correct thermal behaviour inside the combustion chamber.
The LKR7BIX designation identifies this spark plug as part of NGK's iridium series, intended for engines designed to operate within the corresponding heat range and ignition characteristics. Substituting spark plugs with a different code, even if visually similar, may result in improper combustion behaviour or long-term engine issues. For this reason, the NGK LKR7BIX should only be installed in engines where this exact specification is recommended.
This spark plug is not intended as a universal upgrade. It is a direct, like-for-like replacement for engines that specify LKR7BIX or LKR7BIX-P in official service documentation.
