Need Help With Drop-In Filter

[Ammunition]

Hello - I would like to get a drop-in filter, but I would like to know a little bit more about them before I make my selection.

- What is the difference/benefit of an oiled drop in filter versus a dry one?

From the bit of research I did, it sounds like the oiled ones tend to pick up particles better, but need to be re-oiled/maintained whereas the dry ones can be washed/reused easily, but will pick up less - is that correct?

- What drop-in filter will be the most beneficial/would you recommend? I see the K&N one being used a lot, but I also see others like Apexi, etc being mentioned. Is there any difference?

Thanks all for your help and happy New Years

From what I've googled it's the opposite - oiled filters trade filtration efficiency for flowrate. Based on this I've decided to sell my unused oiled filter and buy dry ones instead.

Happy New Year to you too .....

I went with an oiled K&N drop in panel filter ..... really just to see if I could tell the difference. You might call it a $50 experiment. Well, not really an experiment, but it gave me a reason to go to the mail box .... other than to pick up the bills.

I believe that the K&N filter allows the engine to spin up a bit faster, especially at the lower and higher RPM's. Now, that may have been since it got colder here just after I dropped in the filter ..... or my butt dyno is telling my brain dyno what it wants to hear ..... because I swapped out a perfectly good paper filter and paid $50.....

As far as effective filtration, under most climatic conditions, I don't think it makes a bit of difference between oiled or dry filters.

One usually throws away most dry filters and cleans oiled filters (about every 15,000 miles) under normal driving conditions - if I recall proper.

Reduced air flow restriction is always accompanied by reduced filtration. Adding oil to the filter media increases filtration without reducing the flow rate. Therefore oiled media air filters generally offer the best combination of flow and filtration. All high performance air filters are a compromise between flow restriction and filtration efficiency but unfortunately there is no magical filter media that can filter as well as the oem dry paper yet offer reduced flow restriction.

I've never understood when people say they can "feel" an air filter help the motor spin faster at lower RPMs. It seems that at lower RPMs the motor doesn't need as much airflow, so the stock filter should be more that adequate. You should only need more airflow at the top of the RPM range. Or maybe I'm overthinking this....LOL

It's the increased throttle response that they're referring to.
