Man I feel sorry for you. My mother in law has a focus of that era and one of those "lifetime air filters" with a filter minder. Have you ever looked inside one of those? The ones I have seen have a baffle system that is open and for all intensive purposes empty. It doesn't filter for sh*t. Maybe the ones in the Canadian market were different than the U.S. ones, but here is an 04 I believe and it desperately needs an air filter.
It was a terrible system and was never designed to last. I spoke to a mechanic who told me that the focuses of that era were never designed to last more than 5 years and that when people trade them in full of problems, ford doesn't even bother fixing them or take them to auction. They just crush them and sell them to annhueser-Busch to make beer cans.
I would pay extra to have a filter system like that on my car, the lifetime filters with multiple layers of foam filter excellent and will keep dirt out of your engine. The efficiency must be very high on these systems.
Exactly. It was a multi-layer foam system, absolutely nothing like jk_636 is describing.
Actually, one was posted on here in this thread:
