I have a CNG honda city iDSI, giving good milage and reasonable pick. Yesterday I visited Al Mubarik CNG, They advised me to change the venturi. Actually the already fitted venturi is desi one. and due to this the air filter box etc. is a little bit misaligned.
Now they have two venturies which can restore the alignment and also performance of the car according to them. One is imported and costs 1600Rs the other one is local and is of Rs 500 only.
Please let me know whether I should change the venturi or not and if i had to change then which one.
