3. Why Choose CNG Kit Installation in Hyundai Aura?

The Hyundai Aura competes in the compact sedan segment against the Maruti Dzire and Honda Amaze. It is spacious, well-equipped and very refined — but its 1.2L Kappa MPi engine, while smooth, is not particularly frugal in heavy city traffic. Many Aura owners report 13–15 km/l in dense urban conditions, which translates to a petrol bill of ₹8,000–₹9,500 per month for 1,200 km.

After CNG kit installation in Hyundai Aura, the same 1,200 km costs roughly ₹3,200–₹4,200 — a monthly saving of ₹4,500–₹5,500. The payback period for a quality sequential kit is typically 7–9 months. For ride-hailing and fleet operators (the Aura is extremely popular in this segment), CNG kit installation in Hyundai Aura can effectively double take-home income.

Beyond economics, CNG burns cleaner than petrol. It leaves less carbon residue in the combustion chamber and keeps engine oil cleaner for longer. With proper ECU tuning during CNG kit installation in Hyundai Aura, the engine's smoothness and reliability are fully preserved — which matters a lot on a Kappa engine known for its refinement.

4. Hyundai Aura Engine & CNG Compatibility

The Aura is offered with a single petrol engine option in India: the 1.2L Kappa MPi, a naturally aspirated, port-injected four-cylinder unit producing 83 PS and 114 Nm. This is excellent news for CNG kit installation in Hyundai Aura, because port-injected NA engines are the simplest, most reliable and most cost-effective to convert.

• Fuel Injection Type: Multi-Point Port Injection (MPi) — not GDi. This means a standard sequential MPI CNG kit is the correct choice, with no need for expensive GDi emulation hardware.
• Aspiration: Naturally Aspirated (no turbocharger). Turbo-specific high-flow reducers and GDi emulation are not required.
• Emission Standard: BS6. All modern Aura units require a kit with OBD-II auto-adaptation so the CNG ECU can follow the factory ECU's fuel-trim strategy.
• Transmission: Both 5MT and 5AMT are fully supported. The 5AMT needs slightly more careful calibration so shift points stay smooth on gas.

5. Detailed CNG Guide for the Hyundai Aura

Engine & Kit Recommendation

For CNG kit installation in Hyundai Aura, a standard sequential MPI kit from Lovato or BRC is the correct choice. Both brands offer AIS-024 approved kits with OBD-II auto-adaptation and are widely supported for service across India. The compact engine bay of the Aura allows for a clean, quick installation, and the sedan's flat boot floor makes cylinder mounting straightforward.

Performance & Mileage After CNG Kit Installation in Hyundai Aura

• CNG Mileage: 23–25 km/kg (city), 30–32 km/kg (highway) — among the best in the compact sedan segment after conversion.
• Range: 280–400 km on a 60L (approximately 12 kg) cylinder.
• Power Delivery: The Aura is a relatively light sedan (around 1,000–1,050 kg kerb). The slight power drop from CNG is barely noticeable in city driving, and highway cruising remains comfortable.
• Refinement: With correct ECU calibration, the Kappa engine retains its characteristic smoothness. Poorly tuned kits cause a rough idle and hesitation — which is why laptop-based tuning is essential.

Boot Space & Cylinder Options

The Aura's 402L petrol boot is the biggest reason it's such a good CNG candidate. After CNG kit installation in Hyundai Aura with a 60L cylinder, you retain around 240L of usable boot space — still enough for two large suitcases plus soft bags. If you rarely do long highway trips, a 55L cylinder preserves a few extra centimetres of depth and is worth considering.

The flat boot floor means the cylinder sits securely without interfering with the rear seat or spare wheel well. In most Aura installs, the spare wheel can be retained in its original location.

Pros & Cons of CNG Kit Installation in Hyundai Aura

Indicative Cost: ₹36,000 – ₹48,000 for CNG kit installation in Hyundai Aura.

6. Aura 5MT vs 5AMT After CNG Conversion

Both the manual and AMT variants of the Aura are fully supported for CNG kit installation in Hyundai Aura, but the calibration approach differs slightly:

If you own the 5AMT, insist on an installer who has documented experience with AMT-equipped cars. A poorly tuned CNG ECU on an AMT can cause jerky shifts because the gearbox expects a specific torque delivery curve. Our AMT calibration process includes a road test in both city and highway conditions before handover.

7. Sequential vs Venturi: The Only Choice for CNG Kit Installation in Hyundai Aura

Every BS6 Hyundai Aura is fuel-injected and computer-controlled. A Venturi (conventional) kit, which relies on mechanical vacuum to draw gas, is completely unsuitable for CNG kit installation in Hyundai Aura. It will cause:

• Noticeable power loss and sluggish throttle response.
• Backfiring and potential damage to the intake manifold.
• Poor fuel economy and high emissions.
• Rejection at the RTO (no AIS-024 certification).

A Sequential MPI kit uses the car's original ECU signals to fire CNG injectors in sequence, delivering the exact amount of gas the engine needs at each cylinder. This is the only recommended method for CNG kit installation in Hyundai Aura and is required for AIS-024 compliance.

8. CNG Kit Installation in Hyundai Aura Price & Timeline

Note: Prices are indicative for CNG kit installation in Hyundai Aura and include kit, installation, and basic RTO paperwork assistance. Final quote depends on your city, cylinder size, and kit brand (Italian brands such as Lovato and BRC carry a small premium).

9. RTO Endorsement & Legal Requirements for CNG Kit Installation in Hyundai Aura

Driving a Hyundai Aura after CNG kit installation in Hyundai Aura without an updated Registration Certificate is illegal. The RTO must endorse the fuel type change on your RC. We handle the entire RTO process for your CNG kit installation in Hyundai Aura. You will need to provide:

• Original RC.
• Valid insurance (with CNG kit declared).
• Valid PUC certificate.
• AIS-024/AIS-028 type-approval certificate (provided by us).
• Installation certificate (provided by us).
• PESO hydro-test certificate for the cylinder (provided by us).

Endorsement typically takes 7–30 working days depending on your RTO district.

10. ECU Tuning for CNG Kit Installation in Hyundai Aura

The Kappa engine is sensitive to air-fuel ratio errors. A "plug-and-play" CNG kit without proper laptop tuning during CNG kit installation in Hyundai Aura will cause lean/rich running, a flashing check-engine light and, in the worst case, engine damage. Our technicians connect a laptop to the CNG ECU and the car's OBD-II port after every CNG kit installation in Hyundai Aura. We monitor short- and long-term fuel trims and adjust the injection map for smooth power delivery, clean cold-starts and stable idle.

For the 5AMT, we also log the gearbox's torque request signals during a road test, so the CNG ECU delivers torque in a way that the AMT's shift logic expects. This is the difference between a "converted" Aura and a properly converted Aura.

11. Maintenance & AMC After CNG Kit Installation in Hyundai Aura

• Every 5,000 km: Visual inspection of high-pressure lines, leak test, and ECU diagnostics.
• Every 20,000 km: Replace low-pressure gas filter.
• Every 3 years: Cylinder hydro-test (mandatory by PESO).
• Spark plugs: Inspect every 15,000 km; the Kappa engine's plugs are inexpensive to replace.
• AMC: Our Annual Maintenance Contract covers two scheduled services, filter replacement and leak testing — ideal for high-mileage Aura owners.

12. Warranty & Insurance Impact of CNG Kit Installation in Hyundai Aura

Warranty: Aftermarket CNG kit installation in Hyundai Aura typically voids the engine and powertrain warranty. The rest of the vehicle's warranty — suspension, electricals, body — remains intact. Check your specific warranty terms with your Hyundai dealer before conversion.

Insurance: You must inform your insurer immediately after CNG kit installation in Hyundai Aura. The policy needs to be endorsed to include the CNG kit. The premium increase is usually ₹1,500–₹3,500 depending on your insurer and IDV.

13. CNG vs Petrol Economics After CNG Kit Installation in Hyundai Aura

Figures are indicative and assume petrol at ~₹105/l with 14.5 km/l, and CNG at ~₹79/kg with 27 km/kg in mixed driving. Your actual figures will vary with traffic, driving style and local fuel prices.
