Uni Filter's life?

[NSXDreamer2]

Hi, I bought my car used with that filter a year and 4 months ago, I believed I checked it when I just got the car, it was pretty clean. I finally get the chance to check mine couple weeks ago, it's filthy with some mosquitos and a dragon fly on the foam I did clean up a little by wiping those dead bodies off and paper towel to take some dirt off, but without the proper oil and filter cleaner, I didn't clean it very well.

Question is, are these supposed to last as K&N Filters? or I supposed to change it according to the factory interval? I've seen the filter clean and re-oil kit at Comp tech web site, but really have no clue if I need a new one or just need to clean my old one.

Thanks for any suggestion.

You need to clean the UNI foam filters properly so that you do not damage the foam or the adhesive that holds the foam to the frame.

First of all don’t use gasoline to get the oil off (the gas or other solvents will make the foam brittle over time and start eating away at the glue holding the foam to the frame). UNI sells their own brand of aerosol cleaner.

Spray some cleaner on the foam; let it soak in for about 5-10 minutes and then rinse off. All you have done at this stage is to break down the oil from the foam. Now to wash the filter, soak it into a tub of hot water and dishwashing soap. Depending on how dirty the filter is, I usually do this 2 to 4 times until the foam looks like new again. Let it air dry completely and re-oil.

If you store your car over the winter, wash the oil off the foam filter (as described above) to make the filter last longer.

If you follow these directions, your filter will last for a long – long time.

I use standard engine/parts solvent that most repair shops use. It's called Solvoil which I can get in 5 gallon cans from a local distributor in my area. Since I have a parts washer I then wash the filter completely using this and then let it drain for a long time while standing on one corner face (red side) down. After about an hour or so I take the filter and swing it while holding it to get rid of any reidue of cleaner and then use the Uni spray foam oil on both surfaces. You can find this at most motorcyle dealers if you look for it. I've had my filter for over 10 years and it's still going strong. Just remember to clean it regularly depending on your driving conditions. At least every 5,000 miles.

Thanks for your info, in that case, seems like I need to buy a new one, as I obviously had more than 12000 miles and I didn't clean it properly.

Thanks for the info.
