A-Team Performance Silicone Spark Plug Wire Set
The A-Team Performance wire set gives your Ford FE block a solid upgrade. It has low-resistance design for better spark delivery.
These 8.0mm silicone wires handle high heat under the hood. They fit right on your 360, 390, or 460 engine without any fuss. The blue color looks sharp and the boots are made to last through many heat cycles.
Installation is pretty simple if you have basic tools. The wires route cleanly and stay put once you clip them in place. You’ll notice a smoother idle and maybe even better gas mileage after you put these on.
Pros:
👍 Good spark delivery with low resistance
👍 Fits Ford FE 360, 390, 460 engines
👍 Silicone construction handles heat well
👍 Nice blue color looks good
👍 Complete set with all wires
Cons:
👎 Might need separate coil wire

RLP Silicone Spark Plug Wires Set
RLP’s red silicone wires work with many Ford big block engines. They’re made for HEI distributor systems specifically.
This set covers your 390 FE plus other engines like 427 and 428. The 8.0mm thickness gives good spark protection from interference. Red color stands out when you pop the hood.
One thing to note – there’s no coil wire in this pack. You’ll need to get that separately if your setup requires it. The HEI compatibility makes these perfect for older Fords with that ignition type.
Pros:

👍 Good spark protection at 8.0mm

My Honest Opinion:
If you have an HEI system, these RLP wires are a smart buy. The red looks great at car shows and the fit is right. Just remember to check if you need a separate coil wire first.

14mm&16mm Spark Plug Socket Set
This socket set makes spark plug jobs much easier. The thin wall design fits in tight spaces common in engine bays.
You get both 14mm and 16mm sizes for different plug types. The magnetic feature holds plugs securely so they don’t drop. Swivel action helps you reach angled plugs without stripping them.

Don’t skip this tool if you change plugs often. The thin wall design alone is worth the price for Ford engines. It turns a frustrating job into a simple one.
