On edit, even though I did use one on my supercharged mustang I would probably not use one in a boosted engine.
I'm glad you have never had an issue....In 1997, on a brand new car (I'm talking days old) I installed a K&N oem replacement filter...oasis documented it caused (as a result of oil contamination) 2 MAF units within weeks. K&N would not honor their warranty and this was back in the day when you purchased direct from them.....even spoke with them directly at a motorsport event ( where they had their marketing trailer set-up).....just a side-steeping circus.

Hard to believe the K&N passes all that dirt and then clogs up. The dirtier is gets the better it filters.

I know there are thousands of tests out there with different results for each but an oiled, cotton gauze filter is very effective when used properly.

except for one little detail...this (Testland) is an ISO certified facility....and in dirt/off road/high dust applications, yes they have a purpose.

If Ford Motor Company wanted to use a Oil Bath Air Cleaner system wouldn't they still put them on cars and trucks?
I too my 95 Ford F-250 in for a recall (Cruise Control) had it serviced they also replaced the MAF unit. I wouldn't wish one (a K&N Filter) on my worst enemy, not even my ex-wife.

Ok, so I think that this thread clearly states that the oiled filters are not good for street applications. But what about the stock airbox? There are filters out there, like S&B, that have disposable filters. What is everyones opinion on something like that?

If you look at the published flow data, WIX HP filters flow 98+% of K&N and have a much smoother flow post filter plus excellent filtering, for a fraction of the price! I personally run either Wix or NAPA Gold.

the stock airbox is designed to flow more air than the engine can ever use.

Nothing against knN user nor products, but I find their product to expensive specially with it charger kit. AFE Performance filter would be more cheaper and practical to maintain.

I had a K&N drop in filter on my V10. Went to the Ocean and drove on the beach, once I returned home I checked out the air cleaner and sand had gone past the filter. From then on I have had a Motorcraft paper filter in place.

I put the full banks setup ,chip,air intake,filter,inter cooler , plenum , chip,controller , and gained 2 mpg, had power when needed pulled a 38' toy hauler weighing 20k, never once did I need to clean the air filter in 60,000 miles,I believe the are K&N, Granted this was on a 04 / Cummings d3500 4x4, 6 spd , I went from Alaska to Cali and back 3 times and all over in between , was my welding rig it weighed it at 10,800 lbs.

If you change out the stock air filter to a high flow one like the WIX, is it a good idea to unhook the neg battery connector so the truck will recalibrate to the increased airflow?

nope, because the engine will only pull in as much air as it needs.

Then why do all these CAI kit instructions tell you to unhook it during installation? Is it to fool the check engine light or something?

because you need to remove the battery cover to access the area where the filter goes.
