We've been making up the HT lead sets for the early Waterboxer engines in house for some time, mainly because the available kits aren't correct for the earlier engines. Either the wrong ends, or the wrong lengths, or the wrong resistance.
We've had to up our game a little though as keeping up with them has become a problem as we've got busier and busier over the years.
It also makes sense to have the later kits made too as the prices keep rising. Every little helps!
So, we are now having our own leads manufactured to our spec and with our own branding.
Same original spec. Same quality components. Just made in larger batches to save us time and save you money!
