When i first fitted the Ramair filter and started the bike( 12min tune) it kept coming off so i kept tightening but it still came off so i wanked the clips tighter and the rubber split,told Ramair and they replaced it so fitted the second one with the new clips (DID NOT OVER TIGHTEN) and thought all was good until a week later and looked at it and it had split again( now out of quarantee but they replaced it) like it has been said there is a design flaw of not having a lip as the original plenum has on the inside of the filter where it fits the TB's and even not using the correct rubber.
When i spoke to Ramair they said they had no one else have one split!
p.s. you should not have to hold the Ramair on with wire ,cable ties , rope ,glue,cheese......... so goodbye Ramair.
