Looking to up grade the could on my 02 Tacoma v6. I currently have mgk performance spark plugs. But now I'm getting some poor gas mileage. 
Do I go with a set of aftermarket high performance coils or back to OEM
Also this is a off road over land rig I'm building. But I also use it as my daily.
TIA for input and help
