since i installed my turbo setup in august i havent swapped my spark plugs to the step colder autolite iridiums i got from zzp. my first question is do i NEED to swap them out now or should i wait till the ones i have wear out? everythings been good so far so im unsure of wut to do

second question is, that im getting new charge piping. my current stuff is 3" and runs thru the fender. the smaller stuff ill be running thru the engine bay so that it all fits better. when making the piping shorter i know im gonna have to move my maf. where is the best spot for it?

 

so no one's boosted on here or wut?
