The cost of installing a BS6 Sequential CNG kit in a car varies depending on multiple factors such as the vehicle model, the brand of the CNG kit and the complexity of installation. On average, the installation cost in India ranges between ₹40,000 and ₹60,000, though premium kits can cost more. This price typically includes essential components like sequential injectors, pressure regulators, electronic control unit (ECU), the gas tank and necessary fittings such as fuel lines and connectors. Labor charges also add to the cost, usually ranging from ₹5,000 to ₹7,000, based on the workshop and the vehicles design complexity. High-end brands like Landi Renzo, BRC and Lovato tend to be costlier due to their advanced technology and reliability.
Unlike traditional CNG kits, BS6 Sequential kits use a more advanced system that injects gas directly into each cylinder. This method requires highly accurate fuel delivery, precise placement of injectors and sophisticated ECU calibration. These technical requirements contribute to the higher installation cost. However, this added complexity results in better engine performance and smoother operation. The system is also engineered to meet BS6 emission norms, making it compliant with current environmental regulations in India. With stricter emission laws now in force, such compliance is crucial for both legal and environmental reasons.
Though the initial cost may seem high, the long-term financial and performance benefits make it a worthwhile investment. Vehicles fitted with BS6 Sequential CNG kits tend to have better fuel efficiency and significantly reduced emissions. Owners can also expect fewer engine issues related to pollution control systems, which can lead to lower maintenance costs over time. The cost savings from using CNG over petrol or diesel can further offset the upfront expenses within a few years of regular use.
Additionally, installation costs can vary by region and the availability of specific components. Some car models may require more custom modifications, which can also influence the final price. Despite the variation in costs, many car owners find the overall benefits—like reduced running costs, improved engine life and compliance with emissions norms—justify the investment in a BS6 Sequential CNG kit.
