Samiieeyy Posted June 28, 2014 Share Posted June 28, 2014 Hi guys, Sorry if this sounds like a silly question but... Does any one know how to fit the K&N 57i air filter system? I just brought it today for my 2008 Zetec S and am looking to put it on tomorrow. Any advice would be greatly appreciated.

Thanks, Sam Sent from my iPhone using Ford OC Here is the installation sheet - http://www.knfilters.com/instructions/57-0686_inst.pdf I do not recommend the 57i kit, though, it uses an open cone filter that can suffer from heat soak so can loose power (so you get less power than the stock filter/ airbox in some circumstances- but the noise gives the illusion of power) I recommend you fit a K&N, pipercross or green cotton panel filter instead, or fit an encapsulated BMC, pipercross venom or K&N filter, or the K&N typhoon system that claims a 3.76hp increase - http://www.knfilters.com/dynocharts/69-3530_dyno.pdf Quote Link to comment Share on other sites More sharing options...
Samiieeyy Posted June 29, 2014 Author Share Posted June 29, 2014 I already fitted it now!! :( that sucks. Lesson learnt to do more research next time. I will keep it for now and I will just have to look into what the best filter is and get a different one a little later. Thank you for the help and advice.
