I'm also a Satria owner...currently using Mivec rs nose cut...never had problem with the Police...for me just use the part if u want to...try to avoid the road where JPJ always used for ops... :)
as I see from caburator engine, the intake of the air got a pipe which is connected to the ezos piping area
and I think the purpose is to suck in hot air to the caburator is it???
then y we change to cool air??
