Title: Cleaning Apexi filters
Post by: Nik da Greek on August 22, 2008, 11:19:25 AM
As per the title, really. Sorry if this is, like, a real gumby question, but is it possible to clean the filters on an Apexi induction kit, and if so, what would I use? Mine are starting to look black and extermely disreputable, can\'t be good for airflow. I belive they\'re dry, so don\'t need oiling afterwards, is this the case, too?

Ta vurrah much!

I reckon you\'re right! So what is it then? Someone must know

I don\'t want to have a go at washing them just to have them dissolve into a great big mungie!

Well i suppose this guide will do. It\'s for a K&N, but a filter is a filter right? Link is a download for a 5 minuit mp3.

yeah, i would treat it like a k&n. Clean it then oil it as per the k&n recommendations.

The Apex\'i air filters are not supposed to be oiled the are a dry-type filter, they are "supposed" to be maintenace free. With the dry types the best way to clean them is litterally fairy liquid and hot water. Then a nice five minute blast with the hair dryer.

I bought the K&N filter cleaner kit, it contains a cleaner bottle and an oil bottle. only used the cleaner not the oil.
I got mine in the shower and blasted them from in side out and left it running hot for a while.
You will be amazed at how much dirt comes out.

After about 20,000 miles on my old Supra the Apex\'i s looked like they had been a coal mine since the late 19th centuary.
 
10mins later with a bowl of hot water and fairy liquid they were nice and clean and my hands were soft to boot! :)

Cheers, guys, especially Lil Steve. Nice to know someones actually done it without knackering them. Also good to know I was kinda right about them not needing oiling. I\'m sure I remember reading somewhere that that\'s why they\'re good on, like, Skylines where the MAF sensor\'s really close to the filters and gets knackered by sucking the oil off them. Finally, nice that i can get my knackered, hairy-knuckled train driver\'s Wookiee  paws all soft and lovely with the all Fairy Liquid (tm)! :Thumbs-up

You should not clean apexi filter. At the most you can blow them out using a compressor and a blow gun. Once they\'ve done 30k i think, it\'s time to change you can buy just the filter part.

Bugger! I was happy until you came along! :Giggle Is that true? Dunno who to believe now! They cost about eighty quid for the filter elements, which is a lot to spend when you can buy a bottle of Fairy for less than a quid

Thats what the instructions say from memory. I don\'t know what will happen if you try washing them but i would say there is a good chance it will damage it, i would say £80 is not that bad considering they last 30k. Like i said tho if they aren\'t to bad you\'ll be surprised how much crap you can get out with a blow gun.

^^^ what he said - the filters are disposable. DO NOT clean/oil them with K+N stuff, it will make them fall apart, possibly into your inlet tract!:(
Same goes for the HKS mushroom ones.

Balls! Not balls as in I don\'t believe you, I mean balls as in that\'s something else I\'ve got to find money for! Thanks for the wisdom guys. Oh, well, they\'ll have to put up with being black and clagged up for a while longer. At least it\'s safer to run rich than lean.....

dunno if this is any help? http://www.gumtree.com/london/89/21937689.html (http://www.gumtree.com/london/89/21937689.html)

"Contrary to popular beliefs, Apexi Filters don\'t last a lifetime. Apexi recommends inspecting the filter at least every 15,000 miles (25,000km).

After the inspection, you can either cleane the filter if that is feasible or discard the filter and get another one-This is the recommendation of Apexi for Japan where the air is much cleaner as cars with diesel engines have been banned on any Japanese road, hence the gap for inspection of any UK or European cars fitted with an Apexi filter is much shorter, circa 10,000 miles.

Apexi is a paper based filter and cannot be re-oiled and spray cleaned or even washed like K&N, it can only be replaced."

not sure whether this is true, or just one guys opinion i dont know.:wiggle

Title: Cleaning Apexi filters
Post by: BlitzBoy on April 23, 2009, 04:40:43 PM
yep they are a dry type. Just use compressed air to get most of the crud out.

dip and soak in petrol, then air blow thme inside out  and let dry...

If you\'re not regularly cleaning them you can spray them with some Green air or K&N filter oil

Nooo - no oil for Apexi filters! at least, not the apexi power twin-cone filters.  They are indeed \'dry\' filters, and should not be oiled...
Title: Cleaning Apexi filters
Post by: BlitzBoy on April 24, 2009, 11:37:14 AM
yep no oil for the dry type filters, you will actually clog up the small holes and get less air through the filters

Just as a follow up...

I e-mailed Blitz about the cleaning of mine: (I got Blitz SUS cones) and here is copy and pasted reply....

Hi Graeme, my best advise would be not to wash the cone, but blow it out gently and carefully with an airline.
Use a damp cloth to wipe it with if need be. You are correct, the SUS is a dry filter, and does not require oiling.
