first of all if the tranny is good i would only use honda mtf but if it's grinding or anything i would swith to 20/50 full synthetic since it's so hot here you can use that thick. my b16 trany grinded 3 gears and i switched to that and it was like butter. second of all i only use honda filters or if you're a big baller the jdm hamp filter. i also use royal purpal oil. good shit the only ploace i ever see it is sometimes pep boys or o'reillys. and ngk plugs are the best and i like my knology wires it was worth the 175 dollars for them and the extra clutter for the grounds.
