went to the chev dealer and ordered original plug wires last week. when i got them today.....they are gmdelco, however...7mm is printed along the wires.
thats not the right oem equipment...is it ?

part #72096439

thanks,

 

stock wires are 7mm and work fine.

Pro-Stockers only use 8mm wires. Think about it.

 

i'll never run anything but 8mm Taylor's again. cheaper, longer lasting, and much better looking.
