Review on 🔌 B&B Manufacturing S4-28212 Wire Set: Superior Performance for Enhanced Connectivity by Ryan Bennett

Well made, strong and well fitting spark plug leads. The only problem is that these are thicker wires, 8mm, so they won't fit in standard wire guides. I knew this when I bought them and the new wires come with guide clips that they slide into and with a couple of zip ties the new wires are very secure. These cables were fitted to a 1993 Nissan D21 4x4 Hard Cab. The cable set had two coil wires of different lengths, I believe for different models with the same motor. After installing these cables there was a noticeable difference in engine performance. My old wires were really old and worn out.
