Jacob G. I want to thank you for the useful suggestion of blotting a new oiled filter just out of the bag. I have always had to oil my own before. When I get a DIF, I will heed your advice. [I would have pressed the THANKS button but I don't get one until I have 10 posts???????]

Yes at stock you probably won't gain a lot but really how much do you expect for a $40-$50 upgrade and unless you get an intake with a sensor tricker like AEM a tune is necessary to take maximum advantage of the difference. IMO it's worth it also i wouldn't take a brand new oiled filter to the track without breaking it in and it is always a good idea to blot an oiled filter out of the bag because it can start a bit juicy.
