With radiator out (and easy access) could someone please give me procedure for removal of air inlet pipe/s... which have been connected from bottom of original pipes to aftermaket FMIC. Is it straight unbolt/remove/replace with new pipes?? Or, as it appears (from above....back is playing up badly!!) other adjoining fittings to be removed as well? I am wanting to re-locate new pipes to allow fitment of a new twin-pass (much larger) aluminium radiator and twin fans. Many thanks...
