With diesel prices at ₹95/litre in Delhi, many Innova Crysta taxi operators are considering CNG conversion to reduce running costs. The Innova Crysta is not available with factory CNG — but aftermarket sequential CNG kits are widely fitted in Delhi. Here is the complete guide for 2026.
CNG Kit Cost for Innova Crysta in Delhi (2026)
- Entry-level single-point kit (not recommended for Innova): ₹35,000–₹50,000
- Sequential injection kit (best for Innova Crysta): ₹70,000–₹90,000
- Premium sequential kit with 60-litre cylinder: ₹90,000–₹1,20,000
- Installation charges (included in most cases above)
- ARAI certificate for CNG kit: ₹3,000–₹5,000 additional
- RTO endorsement on RC for CNG: ₹500–₹1,000
CNG Mileage of Innova Crysta After Kit Installation
- Single-point kit: 10–13 km/kg (very poor — not recommended)
- Sequential injection kit (60L cylinder): 14–17 km/kg in city
- At ₹76.59/kg CNG vs ₹95/litre diesel, break-even mileage advantage kicks in above 12 km/kg
- Effective cost saving: ₹2.5–₹3.5/km vs diesel at 15 km/litre
- Monthly savings (150 km/day): ₹11,000–₹16,000
- Break-even on ₹90,000 kit cost: 6–8 months
Risks of CNG Conversion on Innova Crysta
- Toyota warranty void: Factory warranty (if any remaining) is voided on CNG conversion
- Power loss: CNG reduces peak power by 10–15% — affects outstation hill performance
- Boot space lost: The CNG cylinder occupies significant boot space — affects luggage for airport runs
- Fitness certificate risk: Not all Delhi RTO inspectors pass aftermarket CNG on older Crystas — ARAI certification is essential
- Resale value impact: CNG-converted Crystas sell for ₹1–2 lakh less than diesel-only equivalents in the commercial market
Should You Install CNG in Your Innova Crysta Taxi?
For city-focused operators doing mostly short Delhi routes, a quality sequential CNG kit pays back in 6–8 months and then saves ₹11,000–₹16,000/month. For outstation and airport-focused operators who need full boot space and maximum power on highways, the tradeoffs outweigh the savings. Our recommendation: avoid CNG conversion on Crystas used primarily for outstation or premium airport runs. Consider it only for high-volume city operations.
