Reddit mentions: The best air filters & cleaning products

In order to actually clean the filter/cone, I recommend using something like the K&N filter recharge kit:

K&N 99-5000 Aerosol Recharger Filter Care Service Kit https://www.amazon.com/dp/B00029WYEY/ref=cm_sw_r_cp_api_jJOQAb7BZ4K73

Step 1: loosen the cone clamp and remove the cone/filter. You can use a hose to pre-clean as much of the gunk and debris as possible.

Note: you won’t really need to cover the exposed intake tubing, because your engine isn’t running or sucking in any air. You can cover it with a plastic bag and rubber band (or shove a towel in there) for peace of mind if you’d like.

Step 2: use the K&N detergent spray on both sides of the filter. I think the directions say to let it sit for a minute to do its thing.

Step 3: Rinse both inside and outside of the filter very thoroughly.

Step 4: drying - shake out as much water as you can from the filter cone. You can safely use a hair dryer on a low heat setting on both the inside and outside of the filter to speed up drying.

Bonus Tip: you can also use some compressed or canned air (like electronic duster) to force the moisture out of the nooks and crannies of the cone.

Step 5: once it’s dry, oil the filter cone with the included oil spray. Don’t saturate the filter, there is such a thing as too much of the oil.

Step 6: re-install your nice clean filter cone and re-clamp your cone.

EDIT: some words. I’ve got the CTS on mine as well, so I made the steps more specific.

• 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

special stuff. here is the kit

that one looks like it has the spray oil, which is better than my pour on oil (much faster and harder to over do). just follow the instructions shouldnt be a problem.
the MAF is easy to locate, do a little reading on cleaning it first, and proceed with caution if you do. they're usually pretty expensive to replace.

This is bently. He is an awesome dog. This is him after a long day. He couldn't destroy a toy if he tried to so I looked for indestructible dog toys on Amazon and this came up. Says it is guaranteed.

This would be my item.

My filter cost me 50 for my 2017 Ridgeline, the cleaning kits are 12, regular filters are around 30.

Pays off after the first cleaning kit, then you are saving 18 every cleaning after that.

make sure your filter has enough oil on it. the roush ones are a oil based filters, the k&n filter oil plus cleaner what I use, and I have had no issues unless I'm cleaning my engine bay and spray hard near it.


or invest In this: hydro sheild

You mean this? It was replaced a year ago and has not been cleaned.

everything from a 96 Chevy Tahoe to a 2010 WRX
Napa Auto Parts in the US sells K&N filters usually double the cost of a standard filter, and cleaning kits are less than the price of a new standard filter. Amazon has them for even cheaper
