Hi Tony, twas on your suggestion that we went ahead and designed an upgrade kit for JCW airbox. We even put up a thread with pics ,I think its called 'GTT/JCW airfilter upgrade kit',maybe you missed it.
Ours also pulls air in from the end which is blanked off normally with a metal plate. So even better flow.We even tested it against JCW 'stock' filter. Check it out.
Its in stock & available from a GTT dealer near you now
-I know its not on the website yet, blame our web designers,
Best Regards Roland GTT
