The plug wires installed easily and were the correct length. Engine works better than before! Recommend!

The wires work well, only issue is there a little limp compared to say Taylor wires and the HEI part seems a little looser than I'd like. But they seem to work well have not had them long enough to say for sure.

Product not as described, does not fit 1971 GM 396. All wires are preassembled and are basically the same length making them way too long to coming close to application described. Very disappointing to have to cut each wire and redo it. Would not recommend this product.

Can’t beat the price compared to local speed shops or parts stores. They always have some crazy color or the angles are way too tight. They look OEM, minus the lack of writing and date on each wire, but I figured I could add that later if I was feeling ambitious from a restoration standpoint or just leave as is. Overall great price, nice long boots that reach onto the ceramic without hitting the spark plug boots or the exhaust manifolds.
