loopy_lee 7 Report post Posted July 7, 2015 Hey trying to find a replacement filter for my Gruppe m carbon e36 m3 intake, its current filter is shot.

loopy_lee 7 Report post Posted July 7, 2015 Finding a filter seems impossible, might adapt the housing to use a k&n cone filter or il trade for a factory one possible if the deal is worth it Quote Share this post Link to post Share on other sites

Neal 544 Report post Posted July 7, 2015 Without measuring the filter looks similar to the element used in the K&N Apollo setups. Can check tonight Quote Share this post Link to post Share on other sites
M3_Power 636 Report post Posted July 7, 2015 One of these might work http://www.ebay.co.uk/itm/TEGIWA-AIRBOX-FILTER-ELEMENT-TYPE-1-/400761531732?pt=LH_DefaultDomain_3&hash=item5d4f3fad54 http://www.ebay.co.uk/itm/TEGIWA-AIRBOX-FILTER-ELEMENT-TYPE-2-/201155000486?pt=LH_DefaultDomain_3&hash=item2ed5c5b8a6 They are the same filters used in the Honda Mugen intake airboxes - so if you have the dimensions you might be able to hit up Honda NZ (official distributor of Mugen products) or another local Mugen distributor and see if they have them in stock. Otherwise Tegiwa is an UK company that made knock off Mugen intakes and uses the same filters made by a third party which is just as good. Quote Share this post Link to post Share on other sites
loopy_lee 7 Report post Posted July 8, 2015 Thanks for the help. Yea 200+ shipping is pricey! Makes me want to just bin it and get a factory box... I measured the circumference of the intake at its 195mm on the outer lip which is how it fits into the housing Quote Share this post Link to post Share on other sites
Neal 544 Report post Posted July 8, 2015 Sorry , roughly right shape but about 165mm across for the Apollo at the widest part. http://www.knfilters.com/universal/apollo.htm Quote Share this post Link to post Share on other sites
loopy_lee 7 Report post Posted July 8, 2015 Managed to find a site in the UK that has the filter Part No: RF-3301A and it's heaps cheaper and a legit part too. Will order that but before I do il try my luck with Honda to try and see if any mugen filters are around. Thanks for the help guys. Il let you know how I go!!
