CNG Fitment for More Car Brands

Your dealer provides a dated quotation with one complete fitment price for the kit and installation, including cylinder mounting, installation labour, calibration and operating checks. Documentation charges and accessories outside the standard kit may be quoted separately. Confirm the cylinder specification, applicable taxes, final payable total and written warranty before installation.

The complete system includes the selected ECU, reducer, injector rail or mixer, sensors, switch, valves, wiring harnesses, pipes and standard installation accessories.

CNG kit price guide.

Compare the specified components, complete installed quotation, installation, calibration, applicable documentation, local support and written warranty. Gold, Premium or imported-brand labels and another model’s review do not describe your car’s configuration. See the comparison criteria.

• Conventional: gas is mixed with the intake air through a mixer.
• Sequential: an ECU controls gas delivery through individual injectors.
• DPI (Dual Point Injection): two port injectors per cylinder require the corresponding Sequential configuration. MIJO’s four-cylinder, eight-injector DPI configuration uses a dedicated 4×8 ECU.
• DI (Direct Injection): requires a dedicated system developed for the direct-injection engine.

Older Audi, BMW, Mercedes-Benz, Volkswagen and Škoda applications include port-injected engines; six-cylinder applications occur among the luxury brands. More recent applications commonly use Direct Injection. The actual engine determines the ECU and injector configuration. A turbo badge alone does not establish DI.

Compare CNG systems.

CNG means Compressed Natural Gas. In a Sequential system, the reducer lowers gas pressure, injectors meter gas and the ECU coordinates delivery. Three-cylinder, four-cylinder and other supported configurations use the corresponding ECU and injectors.

Standard port-injected Sequential systems start on petrol and change automatically to CNG at calibrated operating conditions; the driver can select petrol when needed.

Measure actual mileage by dividing distance travelled on CNG by kilograms refilled over comparable fills. Traffic, load, driving style, vehicle condition and calibration affect the result. CNG mileage is measured in km/kg, not per litre.

For running cost per kilometre, divide the local CNG price per kg by CNG mileage in km/kg. The calculator uses local fuel prices and monthly kilometres to estimate savings and payback. Estimates are not guaranteed or factory-certified mileage.

Litres describe water capacity, not gas weight. For a standard system, a 60 L cylinder holding about 8 kg at 15 km/kg gives an estimated 120 km of CNG range. Actual filling varies with residual pressure, gas temperature, station pressure and cut-off.

Review cylinder size, weight, mounting, valve access, ground clearance, passenger load, usable seating, luggage and spare-wheel access with the installer. Factory boot volume and another car’s installation do not specify the space left in your vehicle; include any commercial equipment in the layout discussion.

Confirm the cylinder manufacturer, specification and applicable cylinder documents. MIJO supplies the conversion kit; cylinders are sourced from cylinder manufacturers.

Contact your MIJO fitment centre with the invoice, system identification and service record. MIJO kit warranty, installer workmanship terms and the vehicle manufacturer’s warranty are separate; original vehicle cover must not be assumed unchanged. Service cost depends on the work required; request an itemised quote for parts, labour and taxes, and follow the car manufacturer’s engine-oil specification.

For software, calibration or replacement parts, provide the installed ECU and component identification, installation history and symptoms, including poor running, warning lights or fuel-level readings. Filters, reducers, switches, sensors, emulators and wiring must match the system. Use the matching ECU software and wiring downloads and components and accessories catalogue. The fitment centre checks vehicle condition, installs and calibrates the system, completes leak and operating checks and a road check, and explains fuel changeover.

Within MIJO’s Conventional and Sequential range, suitable BS3 petrol applications can use Conventional or Sequential; from BS4 onward, port-injected MPI or MPFI applications use Sequential. BS4 and BS4 OBD2 are separate approval stages, alongside BS6 Phase 1 and BS6 Phase 2. The emission stage alone does not identify injection technology.

For Conventional and Sequential fitment, obtain the applicable vehicle-kit approval documents, including certificate validity, manufacturing year and emission scope, and confirm the local RC endorsement and insurance process. ARAI or ICAT references identify the testing agency; RTO registration is a separate step.

Before fitment, your dealer checks the vehicle condition and confirms the applicable vehicle-kit approval.

MIJO does not support the use or installation of a second-hand CNG kit. Choose a new, complete MIJO kit installation with applicable approval documents and written warranty terms.

MIJO supplies independent aftermarket systems. A listed model does not imply OEM factory-supplier or authorised-showroom-installer status. Factory CNG specifications, cylinder layouts, certified mileage and vehicle warranty terms describe their own vehicle configurations.

For current factory availability, variants and vehicle prices, use the manufacturer’s specifications and dated quotation. A factory vehicle’s purchase price and conversion of your existing car are separate costs.

Diesel and battery-electric vehicles are outside this passenger-car petrol-to-CNG guide. Trucks, buses and other commercial applications have separate vehicle and operating requirements; a passenger model listing does not describe their cylinder or load layout.

LPG needs a separate system, tank, components, application assessment and quotation. CNG prices, mileage and fill estimates cannot be applied to LPG. Explore Sequential LPG.

MIJO has a technically developed CNG solution for strong-hybrid vehicles. Export enquiries can be discussed against the exact vehicle and destination requirements. This solution is not currently available for approved retrofitment in India. Discuss an export programme.

MIJO develops and manufactures CNG and LPG systems in Kundli, Delhi NCR. Established in 2001, its in-house product development, tooling, machining, assembly and testing support a company-wide record of 1 Million+ Customers, a 1,000+ Dealer Network and exports across 17+ countries. See our manufacturing capabilities.

Export partners can arrange destination-market documentation, training, spare parts and after-sales service support through MIJO.
