I did an experiment with my V6 Freelander last year.
The standard filter housing is dreadful as it sits on top of the engine. This causes it to warm the intake charge considerably, I've recorded 55°C!! I thought I'd try a large cone filter instead.
Not wanting to waste dyno time, I just rode my own dyno (the car).
I did a few 1/4 mile runs with both filters fitted.
The result was pretty much what I expected.
No difference between the two. Both filters give the same times.
I'm currently working on a nice cold are feed for my KV6 engine as they are proved to work well.

Years ago I stuck a K&N cone right onto the TB with Duck tape, took her out and was blown away with the noise, it was sweet. What caused me to subsequently rip the cone off was the total loss, yes loss of power. I was amazed after that to see people blowing hard about open cones in 180's, you really need to be brain dead not to notice the missing 40BHP with a cone. In-fact you deserve a cone if you like a cone.
