I would like to give them a try but can't seem to cross reference them.

They don't list for aircooled Beetle, only water cooled.

They do list for a 1972 Type 4 ---- IBE1H 10

Personally i'd stick with the NGK.

I don't think those plugs and a MSD system will turn your engine into a fire breathing beast.

Ya, their cross ref sheet shows the plug Glenn mentioned which shows N/A anymore so shows this one as a successor.......

Spark plug tech always intrigues me with how many different ways they come up with to ignite a fuel/air mixture....I just wonder if there's ever any real validity or just snake oil.

(Only thing I've ever noticed is copper plugs are shorter lifespan vs platinum/iridium/unobtanium....that's about it in my 40 years of spark plug inquisitions) ((shrug))

I would remove the "header wrap" asap.

Pulstar´s are only interesting on engines/vehicles that are running resistor plugs. There they - can - make a difference, however small. The largest advantage is that if you for some reason have issues with the sniffer at the test sitethe Pulstars can help bring both the Nox and the HC down.
The Harley Davidson people, or at least some of them, swear that their (newer) engines, approx 2012-on, run better with those plugs. In any case, the downside with them is that they do not last long. If you can get 15000 miles out of them you are really really lucky. The norm that I have seen and experienced is more like 7-10000 miles.

What's wrong with the header wrap?? I'm curious

The claimed issue is, it absorbs moisture and will cause premature corrosion of the exhaust system.

It's a rail, not driven every day and likely sits in the shop, when not in use.

If you have kids/grandkids around. It may help preventing a painful second degree burn.

I think Glenn is stalking me, that is an old pic of my buggy, it's completely different now. Oh and I can't remove the wrap, the exhaust has totally rusted away inside of it. There's nothing left.

In your gallery.

Looking at the manufacturers web site it appears that these are, essentially, a capacitor in parallel with the spark plug gap. On one hand, all spark plugs are a little bit that, but more has some interesting potential — and potential drawbacks too.

As the coil voltage rises to arc point it would store some power. After the arc is established the sustaining voltage is a lot lower so any stored power can be dumped into strengthening the spark. The downside being, without limiting the peak current it could briefly cross into the destructive range.

And they are all resisters too. So there is something hindering the spark and something that gives it a boost.

The best plugs are a Copper plug.

I read where a CDI box, or high energy coil helps starting.

I'd do either before I changed plugs.

Pertronix w/a coil, OR, a CDI MSD, or MSD Street (I think PN 5520) would help. I would buy a used one, made in the good-ole USA way before I bought one made in China...Ebay.
