Just don't over-oil, you'll be fine. I had a K&N on my last truck for a few years that never threw codes. It's when there's too much and some gets sucked onto the MAF that you run into an issue.
I guess you could say having a dry filter would fix this, just because you remove the element of human error where you have to put just enough on without using too much. I switched to a dry filter just because it ended up not making sense to me to run a filter that prided itself on being ultra-high flow but which had to be smeared in oil to still catch enough dirt to protect the engine. Other filters flow less, but because there's more to them they don't require you to add oil to catch most contaminants.
When I switched to a dry flow in addition to not having to oil it, my engine ran better and seemed to be less 'doggish' down-low. I no longer run aftermarket intakes beacuse I don't believe they're worth much in otherwise stock engines. But the one thing I believed was when K&N competitors advertised that a stock engine only really needs and can make use of but so much air. There's no point in a filter that flows 3-4 times what you really need when there's one that still gives you more than stock and everything your engine can use while doing a better job of keeping dirt out.
