Default How To Clean Your CAI Filter

Materials Needed - Note - Beer is not required but it ain't a bad idea!

1. Screwdriver or nut-driver to remove the hose clamps and CAI box cover lid, if installed
2. K&N or equal filter cleaning spray or dish soap (and bucket) cleaner
3. K&N or equal Filter oil - spray can or bottle - I like the refillable spray bottles
4. Bucket and a stiff brush to remove any stubborn debris
5. Few clean old cloth rags
6. Beer
7. Radio
9. TV to watch the ball game.
10. Air Compressor (with the pressure regulator set to 30-40 PSI MAX!) to blow out the embedded stubborn dirt, oil and remaining water from the filter element's pleats. DO NOT use compressed air pressure above 40 PSI because you will blow the filter fabric right out of the filter element. Dunno 'bout you but my filter was $50 so I ain't gonna change that bugga anytime soon.

Remove CAI Filter Box lid if installed-

1. Unscrew the hose clamps on the the filter where it connects to the air intake tube.

2. Remove the air filter from the air intake pipe/filter housing.

3. Tap all loose dirt/debris off the filter on the trash can lid or something you can easily toss out.

If you intend to use the bucket of dish soap method continue at step #4.

If you are going to use a combination of spray can cleaner / filter oil and compressed air method go to the comments after step #10.


4. Fill a bucket of water enough so that the entire filter can be submerged in it (excluding the filter neck) and then add 12 ounces of filter cleaning solution to the water.

5. Submerge the filter in the bucket of water so that the water covers the entire filter but not the filter neck.

6. Soak the filter for at least 15 minutes or so. Perhaps wait until game halftime - so grab another beer and plunk'er down a spell. This is also a good time to clean out the filter housing.

7. Agitate the water by rotating the filter back and forth to further remove any remaining dirt and debris. Use the stiff brush if needed.

8. Take the filter out of the water, empty the bucket and repeat the above steps as necessary (usually three times - boring ZZzzzz) until the soapy water and the filter is clean.

9. Empty the bucket and allow the filter to air dry. Most manufacturers recommend over night or at least 6-8 hours of filter drying time before re-installation.

10. Reinstall the filter. Remaining re-installation is the reverse of the removal steps Step #2. then Step #1.

For the lucky mechanics with an air compressor and spray cleaner and spray oil - you DA man!

Wont even tell you how to take the cover off or remove the filter cause you got the right tools and your way ahead of this.


11. Adjust the air compressor to 30PSI or so but never over 40PSI!

12. POP the Top on the beer to quench your taste buds. Adjust the radio or TV volume to just below "Annoying" and just above "Ya!"

13. Gently tap filter to remove excess debris just like in Step#3. Use the stiff brush if needed.

14. Using the compressed air, gently spray from inside the filter to remove any stubborn debris. If you have stubborn objects then gently use a small screwdriver or pocket knife to get that crap out.

15. Spray the cleaner on the outside and then from the inside of the filter. Tapping softly again to remove any debris. Let the cleaner sit on the filter for 10 minutes and flush with clean water hose from the inside of the filter out-wards. No need to force or cram the debris inside the filter - we want to remove that stuff.

16. Repeat Step 12 as needed! Don't forget to clean out the filter housing!

17. If needed - and usually not required - repeat Step #15 and then repeat Step #12. Slap the butt-head messing with the channels!

18. Using compressed air - MAX 40PSI - spraying from the inside of the filter outward, remove all the water and any remaining debris. DO NOT keep the air gun focused in one spot. Shake it up a bit folks. If it's that bad you need to reapply the cleaner and grab another beer.

19. After the filter is clean enough to reinstall, lay the filter out on old newspaper, your most annoying bills, wifes most precious clothing or anything of no value to you to prep the filter for re-oiling. If in doubt, Repeat Step #12 for liquid courage.

20. Spray the filter oil on the filter but DO NOT over soak it! All you want to do is cover the element with oil. Adding too much means you will have filter oil dripping in places you just don't want to deal with. Besides the oil ain't free.

21. Reinstall the filter, hose clamps and covers as needed.

22. Grab another beer, step back and burp as loud as possible (when the neighbor gives you the thumbs-up you just know it was a good one) and admire your handy craftsmanship.

23. Tell the wife you never saw her new clothes, but you think you saw the neighbors dog running around with something.. jus ain't too sure.

24. Might want to close the hood



What we leave behind are our words and our deeds. Nothing else really matters.

Aftermarket "cold air intake" with a washable oiled air filter. Stock trucks don't have them.
