K&N filters are great for naturally aspirated vehicles. They last forever, and don't require much maintenance and are hard to beat. I only use them on non-turbo vehicles. As a former turbo builder, I don't recommend them in front of a turbocharger.

I just go buy the stock paper air filter.
I figure that if they are good enough for a 4400 hp railroad engine - they are just fine in whatever I have to drive.
Besides, at the normal RPM's that most of us run our trucks at, you DON"T need more air flow, the stock system is more than adequate. Modified, higher rpms then more air flow is required, but at 2000 rpm on a stock engine down the highway, NOTHING more is needed.
K&N loves the hype to sell you something - but look at the dyno charts at 2000 rpm, if they even show it that low......

I've owned it for less than 2 yrs and haven't changed the air filter. When I bought it the original breather cap was nasty and so I really need to get a baseline for how much blowby.

I like the stock breather because it says something about my truck. As long as the element is changed on a regular basis, you have all you need. I change mine every time I do an oil change. Might be overkill, but I feel better about it that way.

I have the stock housing, just changing the actual air filter itself. What you call "the element." I actually need to make the choke heater riser kit thing-a-ma-bob because she hates the cold. Another good reason to keep the stock housing.
