Which year is your Panda, mine is a 2018 1.2 Pop which is Euro 6 which can be quite bad in terms of pulling away & bottom end torque, anyhow I have just fitted a BMC air filter element(factory fitment in some Abarths) in the factory housing Part No FB455/01 & I have to say I have noticed quite a difference in pulling away, hill starts & bottom to mid rev range is a bit more responsive as well, it pretty much feels as it should now with a tiny bit of a throatier note & a bit more nippy

I didn't really think it would make that much difference but I suppose being Euro 6 where it is so restricted anythings an improvement, eventually I'm thinking of a throttle body of a Punto 1.4 8v Fire, 16v won't go as it's a completely different setup with air boxes etc
