Spencer[RL] Posted August 13, 2011 Report Share Posted August 13, 2011 (edited) If its not cone shaped like the typical cone style a cop wouldn't have a clue what it is.. :laff: .. But saying that I would belive that it will need to be enclosed . Edited August 13, 2011 by Spencer Quote Link to comment Share on other sites More sharing options...
cinky Posted August 13, 2011 Author Report Share Posted August 13, 2011 is there actually a reason why they are illegal? ive been told a few reasons, and when i asked the tradies when i was an apprentice they just said they were sh!t but couldnt actually tell me why Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted August 13, 2011 Report Share Posted August 13, 2011 Ive seen these hidden inside the original airbox, or you could go full rangi like me never had a problem. Quote Link to comment Share on other sites More sharing options...
cinky Posted August 13, 2011 Author Report Share Posted August 13, 2011 i don't really want to use a pod filter unless i make up a CAI for it, which i might do depending on how creative i get, or i'll just use the square type that spencer has shown Quote Link to comment Share on other sites More sharing options...
Spencer[RL] Posted August 13, 2011 Report Share Posted August 13, 2011 Just go square type or something not looking like a pod. Quote Link to comment Share on other sites More sharing options...
cinky Posted August 13, 2011 Author Report Share Posted August 13, 2011 yeah thats the plan Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted August 13, 2011 Report Share Posted August 13, 2011 Well, if they were enclosed they couldn't get any air in.... So you end up arguing about what % closed. Why do they want them enclosed? I can't see any advantage in covering them, unless you tube cold air in, and the disadvantage is that it kills airflow. The parasites in Govt are weird !

parrot Posted August 14, 2011 Report Share Posted August 14, 2011 I'm not sure, but I think the legislation is there to reduce noise pollution. Quote Link to comment Share on other sites More sharing options...
Raven Posted August 14, 2011 Report Share Posted August 14, 2011 (edited) It has nothing to do with induction noise. The reason they want the filters in an air-box of some shape or description is to act as a spark arrestor in case there is a backfire through the intake. Sparks + fuel vapours = fire!

Interesting, I'd always been under the impression they were concerned about drive-by/induction noise levels. Cheers. :y: All well & good for those with metal air filter assemblies, but for those of us with plastic items, what the heck are they gonna do? Melt? :lol: The parasites in Govt are weird ! Yup...& some people actually voted for them... Edited August 14, 2011 by carbonboy Quote Link to comment Share on other sites More sharing options...
BUZ440 Posted August 14, 2011 Report Share Posted August 14, 2011 If you go a pod filter you can hide it, Had no probs with inspection, easy to setup even have ducting to the paper filter?? Quote Link to comment Share on other sites More sharing options...
Twinky Posted August 14, 2011 Report Share Posted August 14, 2011 Pod filters are actualy legal. The reason most people get stung for them is because they are not secured properly. i.e just dangling in the air. I bought my missis a car from a cop who had actually fitted extractors and a pod filter. The car is a Mazda 323 SP20. The top hat style filter must be complied, like any other modification. It's not a safetly concern more of an insurance and liability issue. Quote Link to comment Share on other sites More sharing options...
