We've never tested the Magnums with Taylor heat socks so we can't tell you what the results will be. Unless you've had repeated wire failures I would just go with the standard Magnums and GM metal boot shields only. The Extremes are the same interior wire, however, the spark plug end boot is constructed with an even higher temp rated silicone and have a custom fitted heat sock over that boot and a custom fitted sleeve over the rest of the wire.

There ya go!

Hey Jon, do you have wires that fit a '14 5.3L Chevy?

Thanks for the info Jon,
I have had repeated wire failure due to heat but after Workhorse installed the Vent Kit 11 years ago I have had no problems until I installed the Taylor wires. I still don’t know for sure if it is a bad wire or if have something else going on. At the same time I installed a set of ACDelco 41-101 Iridium plugs and left them at the 0.060 gap. I was reluctant to regap them to 0.045 because ACDelco says not to regap them because you could damage the Iridium. I the stocks were at 0.060 so I figured it would be OK.

Yes we do

I believe these will work: https://www.ultrarvproducts.com/inde...oduct_id=17946

If you damaged a spark plug re-gapping it... then you don't know what your doing. The days of bang in them on the bench top to close the gap are gone. Although the Iridium electrode is small and thin compared to a regular electrode or even a Platinum electrode they can be re-gapped and NOT damaged. I have done 100's and not lost one!

One thing that I learned as a mechanic, you can't trust a spark plug to come out of the box with the right gap pre-set. I have a miniature set of water pump pliers that I use (for bending the ground or side electrode). I set my plugs for a medium drag, using a wire gauge, between the tip and ground, @ .045.

ACDelco advises NOT to change the gap. It seams they sell the 41-101s with a .045 and a .060 gap although I haven’t been able to find anyone (on the internet) that sells the .045. Mine came with .060 and they all were right on the money (I checked them).
And on a separate but related subject, the 41-101s are not recommended for the 8.1L V8 according to ACDelco. They are mostly for the V6 engines.

I wonder what would be the reasoning for stating that its not recommended for the 8.1.

The usage of the 41-101 spark plug in the 8.1L engine has been observed while using a Water Brake Dynamometer and electronic scanning instruments under controlled conditions. The operation of the vehicle and performance curves printed from the test instruments validated the use of plugs. This performance upgrade was evaluated by technical engineers and is validated in long term use on 8.1L engines and continues to be provided by one or more trusted 3rd party suppliers.

Let me translate this... Jon ran then on the dyno and verified that they work gapped at .045.

If I were producing a video, it probably would be in 4D.

Which raises another question. Will they work gapped at .060?

[Brazel's RV Performance]

They work just fine at .060, we just found a bit more "pep" setting them at .045.
