If you've ever seen a video of how these are oiled at the factory you'll notice they put very little oil on them. They place a small ring of oil around the center and within an hour it wicks through the entire filter. I used this style of filter on our Ranger and oil it like that and have had no problems with the MAF with over 100,000 miles on the filter (cleaning and oiling it every 10,000 to 15,000 miles).

On the Roush I use strictly Roush filters. Its so huge that air flow and intake restriction isn't a problem and there's not much need for a higher flow filter. Just wish they didn't cost so much!
