Seen a PiperCross one so far http://www.fastcar.co.uk/2011/02/28/pip ... ir-filter/

Does it change the sound of the car? Does it make the engine sound more aggressive? Also, was it the Pipercross Universal Rubber Neck cone Filter or a direct OEM replacement?spr0cket wrote:I have the pipercross, sourced it from Awesome.
Toying with adding the APR pipe from filter chamber to supercharger as think that might be an area of a little restriction with baffles contained.

The prevent the ignition being backed off as the intake air charge increases in temperature from ambient engine heat.
So you get to keep what you have for longer.
Also with forced induction cars utilising any form of charge cooling the benefits of cold air feed can be reduced - not to say it's pointless but the charge cooler will be doing a more effective job than the cold air feed in itself.
Varies from install to install though and as doug says the only real way is to log the changes in temp
Cold air feed on my b7 has made the car pull stronger for sure, I reckon this does add powerCold Air feeds in general do not add power (unless there are other changes to the induction system style and shape)

That's a very bad way of putting it. It implies (as by the comment that you can feel the difference) that you are gaining power. You are not. You are losing it slower.Silas wrote:Stoping power being lost?? Well if that's the outcome it's a gain in power over standard
