Duramake Titanium Spark Plug Wire Boot Protector Sleeve (Pack of 8)

Well for 100 miles they literally sat on my headers and I had no burn through issues or issues with the spark plugs wires. Sadly after only 100 miles my main bearings went to be with the Lord as they were unable to deal with the constant struggle of daily driving. True longevity unkown but for now they are looking pretty good.

Heavy material. A solid buy.

Does the job
