Air Filter Cleaning / Recharge
 

Feel free to move this wher ei should have put it in the first place :?

OK ive never written a tutorial before but here goes my first shot, pay no attention to spelling typos or grahmer </)=- lol if you feel the need, post a spelling tutorial for me..lol

So I deceided to recharge my Injen Air Intake Element today , lucky for you i had my camera and an assistant to take pics 8)

First of all K&N and Injen Filter elements are both K&N Filters , Infact the injen kit even comes with the filter bagged in a K&N Bag... , im not too sure about cleaning the elements on other kits but im sure someone will folowup. (If your concearned and have no clue what an element is hang tight for now)

You will need One Recharge Kit (Available at Auto Zone , Pep Boys , Advanced , You get the picture

You can just ask but incase your self sufficient person heres a picture of what you will need and the contents.

You will also need a Ratchet and a 10mm Socket ( i hope you dont need pics of these)
and if your filter is especially dirty a soft bristle brush

Chances are you will most definetly have to remove your battery for easy removal of your intake system. As seen below it would not be an easy task to remove it with the battery in there :shock:

So go to work with that 10mm socket and ratchet and get that sucker out of there

Remove the Negative (-) battery cable from the post.
Remove the Positive(+) battery cable formt he post.
Remove the two 10mm nuts that secure the battery hold down (be careful not to lose the rods!)

ok now i cannot really procede with step by step instruction for removal of your air intake kit becaus it varys on wich one you have.

After your battery is out it should be quick and easy work removing the intake piping and element.

this should resemble what you see.

remove the Element from the Piping , in this case its just a large hose clamp holding it on (easily removable with a flat head screwdriver)

Now you should have this:

now the fun begins :!:

Open your recharge kit and check for the parts i mentioned above.

Tap the element to dislodge any large embedded dirt. , Then gently brush with your soft bristle brush.


Spray the cleaner liberally onto the entire element
Let the element soak for 10 mins

Rinse off the element with low pressure water, tap water is ok.
:PAY ATTENTION HERE: Always flush form the clean side of the filter into the dirty side. this removes the dirt and does not drive it into the filter deeper.

Next let the element dry
After rinsing shake off the excess water and let the element dry NATURALLY
No Compressed air
No Fires
No Hair dryers or heat guns
NATURALLY!
Compressed air will blow holes into the element fibers rendering it useless
And Excess heat will shrink the fibers restricing air and robbing HP!

After your element is dry its time to re-oil it.
The oil found in the recharger kit has red dye , (K&N filters are whitle like all others , the red coloring comes from the dye in the oil. The oil is the most effective part of the filtering process and should never be forgotten!) The oil is red so you can efficently apply the oil to the element with without missing any sections or spots.

Take your oil (weather it be squeeze bottle or aeresol) and apply it to your filter element. wait 20 mins and check for white spots. if any remain oil the spots as nessecary and let oil set for 5 mins.

Now your cleaning is complete !

Reattach your element to your intake piping and install the intake system back into the vehicle. be sure to reconect any electrical connections an/or hoses/lines.

Your Scion now has a noce clean filter and is ready for action

Hope you found this helpfull and enjoy your clean filter :D

nice write up

Re: Intake Air Filter Recharge (Cleaning)
 

My kit came with a stupid squeeze bottle of oil instead of a spay can.

Does anybody know exacly HOW MUCH oil to put on the filter? I don't want to over do it.

My filter was FILTHY by the way, after only 20,000 miles.

-THE DON

How long does it take for the filter to dry naturally? Are we talking a few hours, overnight, or longer?

Mine was dry in about 3 hrs.

-THE DON

:clap: :clap: GREAT POST

yeah, nice write up

i like you step by step instructions

thanks man i was wondering how to do it i was planning to use a dryer to dry it lol

omg, i should of seen this earlier, i think i did it completly bad, basically after using the spray, i dunked it into a bucket of water, than sprayed it all out until clear water came out from every side, than i used a blow dryer to dry it, sigh. did i seriously kill my intake cone? sigh it still sucks in so much air because i i have this fan thing to blow in it and so much of the air came out so quick. so idk!!!

how often do you guys go between cleanings?

Is the aem dryflow filter any better since it doesn't use the oil?

Same length between cleaning/replacement for the dry and wet filters?

:clap:
Great tech article. Only thing, I couldn't get my Typhoon off. The headlight assembly was in the way. I ended up taking off the bumper--which had to be done to put the intake on. Maybe something different about the 06's. Anyway, it worked great and gave me an excuse to clear the corners......
Thanks for posting

Oh, BTW, the intake has been on for about a year, around 30K miles and was not as dirty as I thought it would be.

Thanx

does it have to be COMPLETELY dry? cause my filter is just moist right now. left it overnight at the garage to dry.

btw, thats before oiling it.

thanks for the info. any idea which is the best filter/cai to use?

Although I'm not 100% sure of this, I'm going to say yes. Mainly b/c simple science...water and oil don't mix so it may not let the oil get to the filter. Not to mention if you put it on the car with water and then go WOT you risk sucking in the left over water. If its mostly dry that part would not be a problem but if a good bit is then you may have issues with it messing up your MAF sensor.

so the K&N recharger is safe on Injen filter?

lol to bring this thread back.. yes it safe and o yeah for some reason weapon-r is saying that their filters are dry flow also. so no oil needed
