Talking to sales about my problems with my 2008 ford explorer limited 4.6v8 has a carbus system in it they said they should work at 89.00 for them but they don't work called them back was told I would receive an email didn't understand that when had them on the phone would not help me with this mess I did order the wrong ones tried to stop the order but there site wouldn't let me put the order number in I tried everything still wouldn't take it so now I'm stuck with 160.00 some dollars on a product they said would work and if it didn't they would be more than happy to return them well that's has not happened
