Alternative spark plug brand to NGK7ECS

Let me explain, in 3 yards less than Chimpongas would.
I have ditched the extenders. A month or two ago mine was running like a pig, with a severe misfire and various other strange running issues. I gradually replaced every component of the ignition system, and most of the components contributed an improvement to a greater or lesser extent - but the one thing that totally transformed the engine was removing the spark plug extenders. That was a "night and day" difference.
I now run BPR6EIX plugs with standard Lucas HT leads with heat socks on the ends and no plug extenders, and my engine is running better than it ever has before. The removal of the plug extenders was by far the biggest improvement. A set of heat socks is well worth the money to allow you to get rid of the extenders.
By the way, I removed the extenders before fitting the new resistive plugs, and the engine ran fine (bloody well, actually) without the extenders and with non-resistive plugs. Probably there was enough resistance in the bog-standard HT leads I'd fitted. (Either that, or the neighbours simply couldn't hear The Archers...)

You don't want to rummage in my sock drawer - most of them have a crusty deposit in them.
....unlike my immaculately clean iridium spark plugs.....
I have fitted the new leads, new spark plugs and have taken off the extenders, anf fitted heat sleeves over the cables.
The cables have also been positioned so that they are well away from the manifolds and the car is runnng fine and much more smoothly.
Driving it around today, the temperature in town was well over 90 and the fans did not come on by themselves until around 98, and then switched off at about 92. Luckily I have a fan overide switch but even with the fans full on the temperature in traffic did not come down lower than about 90.
Is there a connection to this change and the temperature with these different sparks?

Two possible answers:
1. Your temp gauge is misreading
2. The otter switch is the wrong one and you need one that cuts in earlier.
To check the temperature, you need something like Rovergauge, to give you an independent temperature reading.
To replace the otter switch, you only need to spend about 20 Euros. Just get one that switches on earlier.
