Another revelation with the car I was looking at the air filter and I thought mmmmm looks kinda small, so I took some measurement and did some digging and it's the filter of a 3.0 Capri lol

It is tiny, problem is I don't have any more room for width but I do have height room, so after alot if digging I found a k and n high flow air filter that is 50% taller aswell which I'm sure it will need being as it's 7.5 litre
