Now what do you know about a 2k max?
let's see. i think i know more about a max than you do.. i know not to put an intake so that it sucks in air right behind the cooler fans ....

also, do you know the difference between a cali spec or a fed spec...
hint- google it... i believe you must have a cali spec. i have a fed spec.. that is why i have precats on the y-pipe not the headers...

thank you come again.
