K&N High Performance Air Filter, Enough performance improvement to justify the cost? Options

[JawjaPorsche]

I was reading K&N's website about their air filters:

High flow air filters designed to improve engine performance
Designed to increase horsepower, torque, and acceleration

Has anyone put these on their stock FI Teeners and experience any of the above?

I am talking about the filters that go in our stock air filter boxes. Not external modification filters. I noticed Pelican Parts sells then as an option.

I'm here! Sorry I'm late, I was sleeping, or maybe having a life, or something ............. If you're measuring HP using intake noise levels, the increase is huge. If you're measuring engine life resulting from the increase in contaminants being drawn in through the intake, the drop is likely to be significant. Put plainly, the square inches of filter material is often reduced from that of the OE filter by 2 or 3 (or more) times. How do they get higher flow through a smaller area? They make the pores larger, allowing more and larger particles to pass through, along with the air. Coating the filter with oil helps a little, but what about the particles that don't touch the coating?

Think about the initial cost. Think about the cost of the service kit, and the time it takes to do the service, including the drying time after you wash the filter. Sound like something you want to do? Finally, think about that grit you've allowed inside your cylinders, grit that would have been stopped by your "antiquated" but very efficient paper air filter. You know, the one the factory specified when they designed the engine?
