I ordered a performance air filter from www.greenfilters.com these are supposed to be K&N beaters!!! Cost? £40. The package arrived next day. As usual I rapped the outer packaging to reveal this goodie inside!! Yes it's Greeeeeeen! bogey coloured! the reason? so you can easily Identify when it is dirty! Look at this shiney sticker you get!! Instructions in german <img src="http://www.mbclub.co.uk/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=''> but go to their website and they have them (not like you need them) Yes they come pre-oiled and can be cleaned to use over and over.. My Air box of my W202.... Unplug the clips to see the filter.... See the Height difference? WOW!! Bung the new one in! yes its a nice fit! PUKE at old filter! Conclusion? its like giving the car an Inhalr after having a asthma attack! after 2.5K revs it feels much 'Crispy' Highly reccomended! I give it the BiT-Tech Highly reccomended award!
