i diddnt notice any mpg change with intake + tbs... the only time i notice an y kind of change is when i do less city driving ... other than that i get about 13 mpg mixed driving andf then on long trips i get about 17 mpg ... i also have a heavy foot.. some people on here have noticed mpg change though.....
oh yeah .. i currently have the KNOCK OFF AEM intake from EBAY..... but i just ordered the NEW VOLANT POWERCORE intake + ram air kit .. i have yet to reccive it .. but i will post any mpg and or any differences for that matter ..
http://www.volantpowercore.com/
here is a link to some pics of the new volant... it has a wide opening where the filter attaches to... there is some good info on this link since this guy has had the prior volant gen lll and now has the powercore.. he says its night and day ..and it feels better .. but again no mpg postings on it..
... just copy the link and take out the SPACES between the letters...
