Cold Air Intake...

You've got a bike. You think the 90 degree elbow and a forward facing cone filter from K&N is any better than the OEM Harley Screaming Eagle air filter? K&N has great marketing, with dyno charts. Only you are driving in the real world, not in a controlled environment, where they are dyno testing with the hood up & a huge fan blowing cold air right into the exposed cone filter.
I've never had a sensor fouled by filter oil. That can happen when there's too much oil. But it doesn't happen to everybody.
With a ScanGauge reading the intake air temperature, OEM air boxes will have a higher temperature reading. Results will vary with intakes. On most vehicles, they work best when you are driving at freeway speeds. In theory, the faster you are going, the more cold air you will get. The factory air box draws air from a hole located behind the fender. Very good design, engineered to minimize foreign objects from being sucked into the airstream. You are less likely to get bugs, hummingbirds, leaves, cigarette butts, et cetera. On cars where the air scoop is forward facing, I'm always surprised at what gets sucked into the intake tube & lodged in the filter.
The cold air intake has no box, just a heat shield, which allows the big cone to suck in all the air rushing in from your grille while moving. While idling, expect the intake air temperature to be almost about the same as the OEM airbox configuration.
The real question is whether the intake, as designed, will result in any real world advantages. An intake is only a small piece, to a very big puzzle. Over the years, we've learned that you can throw everything under the hood, at the cost of $$$XXX, and there's a huge difference between dyno numbers and real world advantage. After you re-gear, install a transmission shift kit, add underdrive pulleys, install an electric fan, add a custom tuned exhaust, load a custom tune onto your car's computer.........will you be able to tow more? Not likely. It's not as if your 1/2 ton pickup will now have the capability of an F-250. Are you going to the track with your truck? Make it real. See if you can shave a second or 2, off your 1/4 mile time. You will still be driving a heavy truck, not a sports car, and you are not The Fall Guy. Reality is that none of the money you spend will gain much in the real world.
