This is an old wives tale that has circulated the internet for decades now. If this were a known issue then none of these companies would be in business selling them and none of the tuners/shops would be using them in their builds.

I understand, and didn't draw any conclusions for this very reason. This is solely my personal experience and I will not attempt to generalize from a single example. Nevertheless, I'll keep using the dry filter.

I have seen data flip flopping on what flows better. I don't think it makes a big difference either way. Oem uses dry filters...my Rotofab dry filter looks good after 13k miles and 6yrs. I blow it out yearly with compressed air from the inside to get the crap out of the channels. If/When it gets shitty looking, I'll buy another. I am not dicking around with washing and reoiling. If that is what you prefer, all good.

I was always under the impression a dry filter would flow more/make more power. https://www.camaro6.com/forums/showp...54&postcount=7

As far as the oil coating the MAF, I remember that was always talked about on LS1tech. One builder/tuner actually told me he has seen issues with this. But I do believe this could be when the filters are cleaned, too much oil is added. I ran a K&N with a SSRA in my 4thgen. I cleaned it/re-oiled it many times. Never had a problem with the MAF. Just for the hell of it, I got one for my current car too.

Really no reason to believe a dry filter will flow more air, paper simply isn't a pourus. Try using your mouth to blow through a paper filter and then an oiled filter and see which one you flows best. It's really obvious when you do that simple test. As to which makes the most power, the one that flows the most air will always have more potential.

Agreed. If *anyone* was showing more power on the dyno or faster trap speeds running a dry filter, then everyone would be all over it like a homeless guy getting a free sandwich… That’s not what’s happening, so I’ll stick with the oiled until someone proves it otherwise. For most cars under 700-800 HP it probably doesn’t matter.

Fair enough fellas. I never really thought about it a whole lot to tell you the truth. I did assume my oiled K&Ns would flow better vs the STOCK filters but didn't think about same filter oiled vs not oiled. So just curious, why did Ted's test show the dry filter made more power on his dyno? Just to be clear, I'm not saying you guys are wrong. Just curious what you think may of happened on his test? And yes, sign me up for the free ponies

Exactly.

The difference in his test was within the margin of error/variability. On a stock vehicle, a Rotofab with paper or oiled filter will flow more than the engine needs so neither are really going to show any advantage. It's when you start really adding a lot more power that a paper filter is going to show its limitations.

You guys trying to talk flow and oiled vs dry are just deluding yourselves; cai power gains.

When the filter is pushed towards its max, the oiled filter always flows more than the dry. If you have an NA LT1, you won't be reaching maximum flow and there will be little to no difference in power.

Now when you get into an LT4 setup with pulleys, ported blower and larger throttle bodies, the Big Gulp comes only in wet form because it needs the extra flow from the wet filter vs the dry.

Don't overthink it. Wet flows more than dry.
