my car has been going through plugs like crazy. It is like they foul out a set when the motor gets hot when the motor cools down and u put a new set in it runs fine for awhile as long as the motor dsoesnt get hot about a 20 min trip what could this possible be

have you replaced the wires yet? you could have weak spark plug wires that are fouling out the plugs

when i took it to my local garage he took and messed with all the wires thinking that might of been the problem but the car didnt spit or sputter or anything. iI have changed out two of the coils because it showed a miss fire on 2 with a set of new plugs and the day after i changed them i had to change my plugs
