Toyota Aygo 1.0 is now a different car.
I recently replaced the air filter in my 2012 Toyota Aygo 1.0 Fire, with this filter. The process of changing was as simple as opening four clips, lifting a cover, taking out and replacing the air filter. Immediately the car has much more power, it accelerates noticibly quicker. It would stall regularly when pulling away and I thought that it was the clutch that required replacement, but changing the air filter seems to have done the trick. It pulls up banks too, I'm expecting to see an improvement in the vehicles mpg, I have been getting 53mpg but hopefully it will give over 57mpg, though I'm a couple of weeks away from that calculation at the moment, I will update this review, once I have the data.
