Purchased E3 spark plugs from rockauto for my 1995 Chevrolet K1500 5.7L V8 and that is what I received. I didn't find out until pursuing what I assumed to be a manufacturer defect in the plugs that rockauto sold me the incorrect plugs. Because of this my valves and plugs played a game of tag until the motor experienced catastrophic failure 120.4 miles after installation. Turns out rockauto is not an authorized distributor of E3 parts and never contacted E3 for usage information of the parts they acquired from an authorized dealer wholesale closeout. Their negligence has caused me so much grief. They are only willing to reimburse me for the spark plugs! Isn't this fraud?!?!
