Been looking at a few of the air filter modifications that people make especially around the air filters. The main contenders are the K&N air filter replacement which fits within the OEM airbox and the Ram air filter which replaces the OEM filter and drives the air straight down into the engine:
These pictures were taken from other people from the internet and are not mine. I currently have the K&N air filter fitted and have the second ram air filter arriving shortly for testing. From the readings I have done so far both seem to have pros and cons however, I was wondering from people that have tried either style which they feel will have the most benefit to performance? I know the differences are extremely small however, feedback from other users would be appreciated.
