scotty ram air 3

[Kurt Henzler]

after all the horror stories we here about cleaning an afe fitler. i think i may just replace mine. is there a full foam fitler for the ram air 3 that fitlers better than the afe and is it easier to clean.

What is so hard about cleaning an AFE filter. Clean it with Simple Green let dry and spray with the K+N oil no problem.

Kurt, that is what I use now... two layer UNI foam filters.



You can usually just clean the outer layer the first time you need to service it and then both layers every other time.



Great oil analysis' and a very well built filter is what prompted me to go this route.



You can PM me if you would like a filter.

Scotty,

Do you have some ISO 5011 data to look at??

The UNI 2-stage foam filters are excellent at stopping dirt and easy to clean. Since the cells hold their shape they are not effected by the cleaning process like the cotton type filters. These filters are available as replacements for cotton cone filters and are now standard in the Scotty Air Systems units.

Don

So no one wants to cough up some ISO 5011 data????

 

[scotty1]

I don't have this information for you.



What my biggest concern for my products was quality of the filter, oil analysis and egt reduction. To date nobody has reported anything over 7PPM silicon.

Where the easist place to get a UNI for my Ram Air III?

Are local places with an inventory of these large foamies or should I go through you direct?

D



BTW, The UNI filter must breath better than the cottons also. I've always used UNI on my bikes an you can feel the difference.

 

[p-Bar]

Ya more breathing means less restriction , more contaminates in the engine

 

[scotty1]

Ya more breathing means less restriction , more contaminates in the engine

Or maybe more filter media on a larger surface area means more air with the same or less contaminates then stock.

I forgot that the uni was in this test

P-bar,Thanks for that link. That should help clear up all the hearsay.

p-bar - thanks for the link - that was a great test and writeup. It sure looks like the ac delco filter works the best by far - but I'm not sure how much the added restriction would mean in the real world. I wonder if there is even an ac/delco filter in the proper shape that would fit in the scotty3... doubtful.



I have one of the original scotty 3's with the afe filter, and it could not be much easier to clean. . You spray on the cleaner, wait 5 mins, rinse it with a hose and let it dry, then spray it with oil. Not exactly difficult, and my oil analysis results have been great in regards to dirt content.

We have the UNI foam filters for the Scotty units in stock.



We have tried the Scotty RA3 with a cotton filter and the UNI filter on the 2004 in our shop. The UNI definately performs better than cotton with lower EGTs and a slight seat of the pants and these things stop the dirt.

 

[scotty1]

Well, if you believe that is a fair comparison apples to apples then you need to go another route for your filter. For some reason I believe this was a lead in to your report and had nothing to do with the subject that the thread was started about.



How do you explain the low silicon numbers that people have received on not only the UNI but the AFE and the K&N on my air intakes since 1997?



In addition to that... how many have had higher numbers of silicon then what the standard allows? How many engines have sustained any kind of damage from poor filtration with my product and how many people have over 100,000 miles on their trucks with my intake on them? Do you have those numbers?



Over the years I have had 3 failed filters... all of which where manufacturer defects and they got replaced.



I will refrain from commenting further on this thread.

Good grief - I can't believe that "report" got posted again. I thought anybody with sense here on the TDR had accepted that report was a clear advertisement for AC Delco. Geez, gimme a break.

 

[LightmanE300]

Scotty - keep commenting - we're all big boys and can handle the discussion



Of course this discussion is pretty much splitting hairs - as results have proven through oil analysis and egt gauges that either choice of filter in your units works well. I agree that p-bar seemed to be fishing for a reason to drop that link - because if you read his posts, he offers nothing helpful whatsoever aside from posting the link.



Regardless, I do think the link and article have some real merit, and it certainly seems like a much more legitimate method of testing filters. Using oil analyses is not a good way to do it, since every use and interval is different. At least in this test, it was apples to apples in regard to the conditions the filters faced. Those that think it's a paid report of course can revel in their cynicism and conspiracy theories - I'm not on that bandwagon.



I will say, I do notice (which is supported by the data) that both the amsoil filter(diff car) and the afe I have in my scotty3 do really clog up fast to the point their performance is compromised.

I think this ISO test is the scientific way to test these filters. They all got the same exact amount of crap thrown at them, The same amount of air to push through them for the test , can't get any better than that. Enough said
