Just got a UNI as it was also recommended by Specialty Spares to go with their exhausts systems. I got it from Michael at BellaCorse who recommended not oiling the filter at all if you're using it in a TA/SM stock airbox. After I got it I gave him a call back and he reiterated that all their Triumphs have stock airboxes and UNIs and they do not oil them. He said the main purpose of the oil was to keep dirt out where the filter is in a more exposed location. Any thoughts?



Yes. My thoughts are pretty much the same. I think theres a line you gotta draw between what size particles are acceptable. Because theres not an engine on earth that has ever run w/o some particle getting thru the filter no matter HOW good the filter is. The smallest diameter airway in the best filter will only keep out particles of a larger diameter.So where do you draw the line? The old 70's hondas, at least the early 70's ones, had foam filters and went many miles. A guy at rat has one with 100k on it.

Personally i agree with what you were told unless you ride in horrible conditions a lot. I DO oil mine, but VERY LITTLE, and not enough IMO to impede airflow over a non-oiled one to any degree that weould make a measurable difference IMO. I would suggest you oil it lightly just for peace of mind if nothing more. I don't think you could possibly tell the difference and the stickiness may well help at no cost in flow, or at least none that would impede performance.
