Im looking to upgrade my air box to a cone filter K&N or equivalent I don't really know what the benefits or downfalls of this will have on my MPG to start but the main thing is will i have to remap to get the best from the fuel?air mixture change? or are there sensors that automatically adjust this? any other advise to this topic would be great! seen on here that just upgrading to a cotton or foam panel filter will make a difference! anyone with any experience?
Cheers
