🔌 Satin Spark Plug Wire Loom Set for Small Block Chevy with Center-Bolt Valve Cover - R&M Specialties 1120S Review

I think it actually made it easier to thread the nuts and bolts for the wire holders. I also had to drill out…

The kit arrived quickly and complete, looks great under the hood. Having never used a product like this before, I have been working on the optimal installation. It took several attempts to insert each wire the correct length into the guides and push them down. You try to adjust the length of the four wires by using an Allen wrench and box wrench at the same time and hovering over the valve cover. You need three hands. Once they have the nuts and the bottom of the guide wires attached to the…
