I have a Perrin short ram cone type foam filter and need to re-oil it....

1) Is there any problem using K&N filter oil on it, the K&N is oiled cotton IIRC???

2) Is there any easily substituted, readilly available oil that can be used??

:)

Hm, I'd use the mfr-specified oil to be sure, don't want to compromise filtering.
Yes the K&N is cotton vs. the Perrin foam.
You could ask Perrin directly but you know what they are going to say.
Of course, this being NASIOC you'll be getting plenty of advice- ;)

Speedabsolute got the UNI recharge kit to my house quite quickly.

I was gonna use(insert interesting, but unlikely kitchen product :rolleyes:...don't wanna give anybody bad ideas :lol: )...really...until I thought about the temperature that it may see and that made me think that it may 'cook'...a mineral oil would have a higher service temperature.....

When thought about for a sec....the oil, really, is only there to make the filter 'sticky' so that junk sticks to it....so it shouldn't matter what oil is used as long as it won't react with the filter media in some unintended and interesting manner....:rolleyes: :lol:

I'ma give it a shot, the K&N junk.....I'm moving and everything is gotta get done wikiwiki....like tonite...

Thanks...

:eek:....just got back from a little 'BLAST' after I put the Perrin short ram back on :eek: :huh: :devil:.....nice cool nite and free flowin' intake = :eek: :D

The oil needs to do more than just "be sticky" though, right? You yourself point out that it needs to not burn at underhood temperatures. Also, It needs to be sticky enough not to come off even after it's gripping some dirt, and it needs to have an appropriate viscosity so it doesn't flow and collect in low spots, over the whole range of operating temperatures... right?

....of course its physical and mechanical properties are important...but trapping dirt is why you put oil on it and if the oil has all those other properties and does not trap dirt it is uselss....NO...???

I did think about the whole thing at length which is why I elected not to try an 'alternative' product, although in hindsight, I'm sure it would have worked ;)

Agreed. I was just saying that it's plausible that different filters would have different requirements... Oil might stick better or worse to foam than cotton, for example. Were I in your shoes I'd try to scrounge up the cash for the oil specified by the filter's manufacturer.

Actually, my girlfriend has successfully used Pam as a food-safe version of WD-40 or PB Blaster before...

...yeah...thanks ;)...but I'm so broke if air wasn't free, I'd suffocate.

...and Pam is an interesting product....I've been inventive with it in the past....in the shop and in the bedroom... :devil: :D :rolleyes: :banana:

The K&N stuff is part mineral oil, some kinda mixture with some red dye added to show what coverage you've done.


...You guys running the oil filter panels. Are you guys spraying down your MAF sensor with dielectric cleaner to get the oil deposits off?

Motocross air filter spray. Designed for foam air filters. Needs a solvent to get it off the filter, but dirt sticks to it like nothing I've seen. If you have a buddy with a dirt bike, he's probably got some in his garage. You won't need much.

Wait, you used PAM on your air filter?

[Improvise Motorsports strikes back...] :D

I might have to try this with my AMSOil foam panel filter when it's replacement time... :)

Update.......the K&N filter oil on the Perrin cone filter has produced no obvious ill effects to the filter media.....I applied it in, what I hope was, an even and sparing manner and the 'inner' media(the Perrin filter is 2 layers) shows only some small spots of bleeding of the oil on the inner layer. I have no real way of knowing if filtration is adequate, but I am forced to assume that it will be until I can re-clean and re-oil it with the specific product.

Thanks, all....;)

Amsoil has a aerosol spray to oil your foam panel filter. Works great! Just did the clean up and oiling... :)
