i noticed the same thing on mine i know that stp makes a throttle body cleaner that i have used on N/A engines but i don't know if u can use the stuff on our engines because of the SC/intercooler and i'm not sure if the impellers are teflon coated but i think the throttle body cleaner would eat that right up can anyone help out here? i would love to use this stuff if its safe
