using riser/non foulers to increase fuel economy
Hey guys & gals, i have a 8g galant & i have a question. Ive read in a few places that running your o2 sensors on risers will lean out your air fuel ratio & boost fuel economy. Is there any truth to this or is it like every other b.s economy mod? I have to change my sensors & cats so i figured if this can give me a boost, id throw them on.
