2006 Ford F-150 - Project Fast-150: Part 5

Posted in Project Vehicles on August 20, 2014

We recently upgraded the ignition coils on our FAST-150 project truck, replacing the stock coil-on-plug units in our three-valve 5.4L V-8 with ACCEL SuperCoils. The manufacturer states that they utilize advanced bobbin technology, highly specialized silicone magnetic steel cores, along with optimized winding, resistance and turns ratios to deliver 10-15 percent more energy than the OEM coils.

These are essentially a bit hotter, high-performance replacements for the OEM coils. With our stock units nearing a decade in age, we figured it might be good measure to swap in new units, and a boost in quality couldn’t hurt. We got the convenient eight pack to do all the coils, but they’re also available individually should you need fewer for any reason.

Installation was fairly straightforward and took about an hour to replace all eight coils. The ACCEL SuperCoils are competitively priced, cheaper than factory replacement units and comparable to OEM replacement units. The pack of eight is an even better deal per coil cost. While we can’t say by the seat of the pants if the engine performance is any different with the SuperCoils, we’re confident that we’ve got a reliable set of coils in our truck that should last us for a long time to come.

With the small retention screw that secures the coil to the head removed, the coil can be pulled free from the head. Also, the low voltage electrical connector has to be removed from each coil unit.

The ACCEL coils appear to be nearly identical in size and are molded to slip right in place of the stock units. They’re constructed with high-temperature epoxy that resists shock and vibration, while increasing thermal conductivity. This should improve service life.

The coils sit on top of the heads and there are a good number of hoses and harness wires blocking access to some extent. However, removal and replacement was not that difficult using some long swivel extensions to get our 7mm socket down to the retention screws.
