If you start to notice spark blowout during WOT it's time to take care of your plugs. I wasn't able to get to my spark plugs for three weeks and I noticed my daily commuting fuel economy dropped by about 10%. Even though I don't drive in WOT that much the plugs weren't igniting the fuel as well and I was leaving unburned fuel to go into my exhaust system.
