My new Fujitsubo Legalis R typeEVOLUTION cat back exhaust will be coming from j land in novermber, in the mean time i was wondering what to do CAI wise and intercooler wise. so far i have a dodgey cai which consists of a KnN pod filter boxed and with the original ram intake for the stock system mounted on it. is this suffice or will a real CAI from ARC or HDI or what ever brand do me better considering their cost. Also not sure as to what is their intercooler wise, i cant say no to ARC as they have a direct factory replacement available, will an evo cooler fit or can anyone suggest any other brands. i apologize for the long speel but im getting serious with my car now and i need best and all the advice i can get cheers all, thanks for ure patience with me
