    Rcm filter wanted

    Has anyone got a rcm air filter they want to sell in good condition or new. It is to fit my rotated gt30 i understand they are no longer selling these.

    Cheers.

    It's just a K&N.

    Just buy whatever size you need.

    the RCM cones use an oddball "copyrighted" intake diameter and historically where available in 2x lengths.........

    at this moment in time only the shorter of the 2x options is available with no sign of the longer variant being produced anytime soon........

    Is it not just a tapered cone with a 5" or 6" inlet ?

    Green sell a lot of universal ones too

    It is mate but its longer and not so tapered i believe. What power do the shorter versions support does any one know.

    Pretty sure Mark at Lateral supplies cones and filters.

    Or plenty of universal options of alloy trumpet on egay etc then buy a filter.

    And even the smallest filter you'd fit on one isnt going to limit the power of almost any Subaru engine. But bigger is better.

    Im running 580 just want something thats not going to limit anything. If the shorter one does the trick then so be it... i know graham goodie sell a cosworth filter that is larger but i think they are just the same as stockcars/rcm short version.

    This is the one i have but its seen better days. Only option i suppose i have is shorter filter but longer silicone pipe so it sits into the wing box more.

    Nothing difficult about getting a new filter there.

    The difference between a 150mm filter and 156 is small relatively speaking. There would be no difficulty fitting one onto that if that is the size of your cone.

    Green list theirs as 150mm. K&N list theirs as 152mm and all manner of sizes with that hole.


    https://www.knfilters.co.uk/search/univcone.aspx

    Buy filter, fit filter, job done. It isnt difficult.

    Or here is a place selling filters/cones, just buy one to suit whatever inlet size you need. ( Although they dont state make of filter, I'm sure they sell the trumpets )

    Or one selling both, seem to list same size as RCM might be at 160mm flange.

    Stevie the shorter version i do not think will work as the way the intercooler pipe runs underneath.. if i moved the filter forward any more this would push the filter up making it hit the bonnet.

    Matty pm sent mate.

    if the long one fits, the short one can do nothing but fit and leave more room.
