Bad design
The wires themselves seem to be decent quality, but I can't for the life of me understand why they angled 4 of the 8 spark plug boots. These are for a GM 454, so they should all be straight. That's what I thought I was getting, but apparently I didn't look at the picture close enough. The angle causes them to touch the manifold bolts. Not Good! I may try to straighten the clips and put straight boots on.
Bottom Line No, I would not recommend to a friend
