Do you think this "Fuel Saver Module" is legit?

I change air filters with each oil change

To each his own, but in my opinion, that's a waste of money. The air filter only needs to be changed every 30k miles. I take mine out every 15k miles and clean some of the bigger crud out of it, but it still looks pretty good.

+1. I give it a once over every now and then but it's not really necessary to replace it that often. I usually replace air filters once a year, usually during my spring cleaning.

That schedule is not at all unusual if you live in a dusty area.

Methinks that JJ just might know what he's doing based on where he lives and the kind of driving he does.

Just my .02.

That's why I said "to each his own". Even in highly dusty areas, I've never heard of a recommendation to change your air filter more than once per year. That doesn't mean I'm not wrong, but I would find it highly unusual if the filter was that clogged between oil changes that you couldn't see a 100W light bulb behind it (the rule of thumb for replacement).

FWIW, my dealer suggested replacing my engine air filter during my 22,500 mile service (vehicle was on the road for only 9 months). I do not drive in dusty conditions. I suspect that I could have waited until the 30K service, but I gave them the go-ahead to replace it for peace of mind.

I plan to change out every 10-15k miles or so. I let the Fusion go to near 20k, and when I put in a new filter shortly before getting rid of it, it drove like a new vehicle. Filter didn't look bad either.

@Brett - Hmm, your filter looks nothing like mine. And we both have V6's, interesting.

That is interesting, I was also thinking about re routing the air intake cause it sucks up a lot of crap and maybe even adding a turbo charger to the end of it. I don't know its just the seal were the air intake is, is well not sealed and is getting sucked in towards the air filter.

My air filter was SHOT at 19,000 miles. When I changed it out, I noticed a difference...it was THAT bad!
