  • A filter shouldn't void a warranty, and K&N even offers to fight warranty disputes with dealers who claim the filter did it

    (side note, not sure why everyone here says "GET A GREEN FILTER!" instead of the best known high flow filter ever - K&N)

  • The top actually secures the filter in place. You can take it off, but I would check it once a week to be sure it didn't pop off the intake tube.

  • a high flow filter is for increased air flow (easier/faster air intake) and not temp decreases

    To address ur other concerns:

  • I have a snorkel and I have NEVER had water on the filter, but I also leave the airbox lid on (my 2013 has a ~1" gap between the hood and bumper that water likes to go through to the engine compartment)

  • Oil coated air filters require you to wash and re-oil them every so often. The oil is what catches most of the dust. You can buy a cleaning kit or larger portions of the cleaner and oil. K&N says every 50K miles, but I do it once a year (20K-25K for me) It's a pretty easy process: Take filter out > spray from inside out with garden hose > coat in filter cleaner (special stuff) > repeat garden hose rinse > repeat cleaner > repeat rinse > rinse from outside at angle (not to push dirt into fabric) > pick off any stuck on bugs/grass > let air dry (8-10 hours) > evenly coat with oil (spray on is easiest) > let sit for 30 min > re-apply on any light spots > let sit for 30 min > check for light spots (re-apply and wait again if necessary) > install > done


    If you're that concerned, I'd go with K&N's filter (since it's closed ended) and leave the cover on, but I haven't heard of any reports of water getting into the filter otherwise
