Good catch.
Yes they are of smaller displacement. 1.0L vitz.
The owner is more inclined towards these because I had somewhat different experience with them.
Last year when I bought my car (4afe) it also had smaller cc injectors. Those smaller injectors used to give me 9-10km/l in mingora city which is quite good because here is something for you guys.
No other car even old 660cc let alone new 1.3 or 1.5 can achieve more than 7 km/l in here because of bumper to bumper traffic and short commuting.
New Mira es, Honda N one and Prius/aqua give max 13 km/l in mingora city.
Our civic 2017 did max 6-7 km/l in here. Which in isb city would easily do 12km/l.
So you can guess what traffic here is like or those who have been to mingora know about this.
So after changing my car injectors to original 4afe yellow injector it avg in local came down to 7km/l max.
But with these original injectors it easily gives 10-11km/l in isb city.
Why did I change them?
Because the avg on highway way just not acceptable on those smaller cc injectors which was around 12-13km/l but with original injectors it easily give 15-16 km/l on highway.
So final verdict.
If someone is living in congested city like me with Short routes and more traffic, than these smaller injectors may work in their 5afe/ 4afe engine to give better economy.
If they live in big cities like Karachi, Lahore and isb with open road then it's useless to put smaller injectors.
