Hello,
Depends on location
Like in Delhi - Sequential kits are getting endorsed only in 2010 Model and later.
CNG Fitment center are having approvals for fitting the same kit only. Prior to 2010 make - conventional (Open Loop or closed loop Kits can be fitted). Unsure if the conventional kit can be endorsed in Delhi, but if the car is Haryana number then endorsements are happening. It cost around Rs 17000 - 20000 for these conventional Kits.
We are not recommending in conventional kits as of now due to some issues related to engine performance were reported in terms of degraded pickup and the fact sequential kits are much more advanced in technology
Been this car is 2007 make - conventional kit can only be fitted on same
Details -
Sequential Vs Conventional Kits
Hope should help !!
