MSD wires = Huge fail since Holley bought them.

I have been a huge MSD wire fan for 40 years, had nothing but success with them.

Then Holley bought them, we were living off the original left over stock in the warehouses for roughly a year, then we started seeing unexplained misfires.

We were testing them with a simple Ohm meter and finding a bad wire here and there.

Now we are seeing 6 out of 8 bad right out of the box.

Sorry Holley You ruined a good thing, MSD wires are Trash.

This forced us to look elsewhere.

We contacted Moroso because they always have had a great wire but didn't have good fitment for the LS and LT.

We sent them our specs and they build them for us now to our specs.

We are 8 months in and every wire is perfect!

They are doing extremely well in very high powered road race cars which is the perfect test for any wire.

We are using them in all of our builds and will carry our logo from here on out.

We even have a specific wire for Magnuson 2650 cars, much shorter since the coils are moved down.

Ted.
