I'm currently into CNR (condor resources) for a few quid after a tip from my dad
Down to 6.6p today but big news expected this week a few forums are suggesting a long term (18months) price of around £3.60 though
Also no headlight washers & theres an extra pipe from the intake pipe to the plenum. Aswell as a million other ways which you will find with a quick search
Adam @ Z1 lists it. Theres a few traders on my350z that have them in stock aswell.
Its pretty expensive for just a back box though, I think it worked out around £400ish
Looks nice though
