An original style air filter sits into a recessed fitting in a box with the intake TUBE going onto the intake manifold. There is absolutely no way that the proper filter can be "pushed up a pipe". So either you have an aftermarket air intake tube with an oddly fit air filter or youre not explaining clear enough.
Miscommunications are only going to work against you, so its in your best interest to try your best to describe clearly or at least provide acconpanying pictures.
