I've removed more MSD units than I can remember. I believe they have good marketing department and have spent a bundle on advertising etc. reminds me a bit of Fram oil filters except they do produce a good product. But, I really don't feel there is a need for them on a street car that occasionally sees a little action on the track.
I feel the same on plug wires. 10mm is becoming common, why not just go for 12.5, 16, or 19 mm 🤣🤣
if you're running 14:1 compression on alcohol maybe but on a street car? waste of money IMO
