What kind of filter did they have? The AMSOIL Ea Air Filter is good for 4 years, just need to refresh it by hitting it with compressed air stream (oil-less).
I dynoed a stock replacement Ea Nanofiber Air Filter today on my 1998.5 Ford SVT Contour 2.5L V6 daily driver, and realized 6 peak hp, and 8 ft-lbs of tq in the lower end! That is without changing to aftermarket piping... I'll post up my dyno shortly.

I want to explain to you the benefit of the Ea Nanofiber Air Filters. As I mentioned in the last post, I ran 2 dyno runs with the OEM Paper Air Filter, and then swapped in the AMSOIL Ea Nanofiber filter (NO PIPING, just put it back in the stock box). I was expecting a loss of horsepower and torque, thinking that the more tightly woven nanofibers would restrict air flow. This however is completely counter intuitive. I actually gained 6hp at peak rpm of 6200, and also more notably at 3500rpm I realized 8 ft-lbs of torque! Just by changing my STOCK REPLACEMENT FILTER... When you combine that with a freer flowing intake like the INJEN tubing system, this would only be expected to improve further!
I can sell you the filter and test it out, if there isn't a noticeable difference you can send it back and I'll refund you the money. Otherwise, I'd need to find some locals to test this out to get the dyno #'s unless you want to prove it.
They are good for 4 years or 100k miles and are easy to clean with compressed air, forget about oiling your filter and needing to clean your MAF forever!
Well let me know if you are interested. PM's work wonders!
