For those of you that are using the Spectre filters for your bottlefed air mod, are you sure we're supposed to oil them? I know it sounds dumb since they're cotton fibre filters, but when I bought mine, I looked at the package, and nowhere on it was there a mention of oiling the filter or if the filter came pre-oiled and ready for use. If you look at the larger Power-Adder filters, their package states "Pre-Oiled and Ready for Use" and there are instructions to clean and oil them every 6 months. Even the cleaner/oiling kit by Spectre does not mention the small profile cone filters on their list of uses. It says "Use this Air Filter Recharge Kit on any Spectre PowerAdder High Performance Cotton Fibre Air Filter. PowerAdder air filters are washable and reuseable and add horsepower to your engine!" The pics on the box only show the P4 and P5 PowerAdders and some round element filters. Nowhere does it mention the short cone filters. I oiled my filter before I installed it, but I can't help but wonder since neither the oil kit nor the filter package itself says any single thing about needing oil or being rechargeable. Same thing with the crankcase breather filters. They're cotton fibre, but do not mention needing oil or being able to clean/reuse them. I oiled my breather filters too though. For those not sure... these are the filters I'm referring to.
