spark plug non foulers..Make your engine leaner?
ok so i was reading on the o2 sim for adding headers and cameacross this thread. http://forums.maxima.org/5th-generat...wn-o2-sim.html
carrrnuttt pasted a site (below) that states using non foulers to up your mpg while adding performance by leaning out your fuel mixture. now i can build an engine and all but ecu's, o2, and electrical work is more greek to me. so i was wondering.. with stock ex manifolds would this increase mpg and add a bit of power to the engine. discuss..

edit: ok im gonna brainstorm this and this is what i came up wit hbut not sure if it makes sense.
With the o2 spacedout it will read less oxygen, thus fooling the ecu to thinking it is not getting as much oxygen as it really is, this in turn would make the ecu dump less fuel in which in turn would advance timing as well inducing a better mpg and more hp and tq... am i correct on this or am i way off..?

That would probably make the engine run leaner but that is not always good. During closed loop, the ecu is keeping the AFR at the optimum level.
Also, those anti foulers will not affect the WOT performance because the ecu uses the MAF for open loop readings.
