Default Spark plug wires.

Do all LS1 based engines use the same size wires? Would a set for an LS1 fit on my LQ4?

Thanks ahead.

When I got my Thundervolt 50's I ordered the f-body set, they were to short. I swapped them for the truck version and they were fine. Both wire sets were designed for the LS1, just in different platforms.

The coils are further up on the valve cover than on the f-body. Some wires you might can get away with and some you can't ... not to mention the vendor might have been smart enough to realize you made a mistake ordering and sent the right wires anyways.
