Texas speed plug wires or Granatelli

KILLA BEE · 01-18-2023, 03:26 PM

Msd (as usual) plug wires were the cause of my misfire in my prior post even with boots on them. Never again. Well anyway my tuner suggested Texas speed they are shorter at the spark plug and angle straight up avoiding the headers completely. I did some research and seems granetelli is the best but twice the price which I’m not worried about. Any experience with either one?

I had MSD and one plug git burned so I bought the Granatelli with there heat shield and no problem they look nice also. Get the high temp wires which are a little more but your safer.

I put ACCEL w/ceramic boots on mine but seriously doubt I realized any benefit over OEM. Save your money unless you're trying to dress up your engine bay.

Granatelli ones have been absolutely perfect. No issues at all past 2 years I’ve been running them.

I run the Granatelli wires with no problems.

I have switched 3 times now and absolutely love the KATech High Performance Wires. They connect solid, shrink coated at both ends and much thicker then 8.5mm. Had to switch boots over to ringless DEI Titaniums to fit.

I run the Speed Engineering, especially if your running headers, they make their own wires and you can buy them in 10" which is standard but the 12" work best with the headers. I've run them on my 16SS, my C7 and 2022 Lt1 even though I don't have headers on it.

Granatelli are top notch, but for a cheaper option the Speed Engineering are solid as mentioned above...

Honestly, I think King agrees with me on this, there is nothing wrong with the stock wires unless you are just wanting a better-looking setup. I haven't installed them yet on my Lt1 but have them ready to go as soon as I get motivated to install them, been cold here in Missouri so no big hurry since the tracks don't open till March. I made 707/662 on the stock GM wires.
