you guys can tell the performance effect of an air filter?
when i finally opened up my rx7 filter box, there was a sheet of plastic
covering almost the whole element. i took it out and it didnt seem to make
a difference. maybe it was because it was a 10 year old paper element.
also, having no filter on my probe for a short while (fell off)... didnt
notice that either.
when my cobra was running on 7 due to a toasted wire (damn equal length
headers) i couldnt even tell.
is my butt-dyno really out of wack???
