Top-Performing Walker Products 900-1413 Thundercore Ultra Spark Plug Wire Set Review

As a hesitant automotive buyer, I was disappointed with the results of these replacement parts. As my tests showed, the ignition parts did not provide the improved performance and efficiency promised. While the price may be enticing, it is not worth sacrificing reliability for savings.

Worked great for my 1999 Dodge Ram 1500 5.9L. Between this and the Wells F2128 distributor cap and rotor kit, my truck runs great and the check engine light stops flashing from being out at higher RPMs.

Spark plugs fit well and gave me more spark, now all I want to do is step on the gas. I bought some dielectric grease in my boots and it found it right away and made a nice click. They didn't come with a plastic heat shield so I used a few extra pieces of plastic to keep it off the engine.
