R4WLV Posted October 21, 2014 Share Posted October 21, 2014 Hi, I've read that the cosworth filter is a good upgrade, but how often does it need replacing, I assume that because it is not a filter that you oil, it will need replacing, probably as often as the oe one. At £34.80 delivered from Demon Tweeks, it's not bad but how long will it last? Cheers, Mart. Quote Link to comment Share on other sites More sharing options...
Scooby Pete Posted October 21, 2014 Share Posted October 21, 2014 It says to replace at normal service intervals. Quote Link to comment Share on other sites More sharing options...
Sandals Posted October 22, 2014 Share Posted October 22, 2014 I use a Pipercross fry type filter... and it say's that it is washable! http://www.pipercross.net/pipercross-rectangle-performance-panel-filter-length-284mm-x-width-172mm-pp1128_p24037897.htm Quote Link to comment Share on other sites More sharing options...
quit Posted October 22, 2014 Share Posted October 22, 2014 pipercross, HKS, cosworth they are all good 1 Quote Link to comment Share on other sites More sharing options...
Scooby Pete Posted October 22, 2014 Share Posted October 22, 2014 The Cossie is not washable as its got a much finer weave than piper cross so does a better filtering job. Bear in mind you have spray a coating of light oil onto the washable ones so they trap the fine particles, overtime this oil will work its way through the induction system having coated the maff sensor on its way. Obviously this isn't over night it take a long time to build up. Horses for Courses at the end of the day. Quote Link to comment Share on other sites More sharing options...
R4WLV Posted October 22, 2014 Author Share Posted October 22, 2014 Thanks, the service schedule says to replace every 30k so not too bad. Probably go for the Cossie one to avoid any oil on maf problems later! Quote Link to comment Share on other sites More sharing options...
Scooby Pete Posted October 22, 2014 Share Posted October 22, 2014 I'm not saying the washable ones are bad, just that there are down sides to them. As the Cossie one has in having to replace it. They both have their pros and cons. The maff issue is more prevalent on the classics. Due to the maffs age, they are a weak spot on the classics. New age won't be much of an issue till later in the cars life. Quote Link to comment Share on other sites More sharing options...
R4WLV Posted October 22, 2014 Author Share Posted October 22, 2014 Well, 12,000 miles a year so it'll clock up really quickly. Waiting to look through service history first, cars just been serviced so may have just had a new air filter fitted. Quote Link to comment Share on other sites More sharing options...
