Conventional wisdom agrees with HB Chris✓. Most recommend using standard copper core spark plugs as these were originally equipment from the factory.
That said, if you experienced no problems with Denso Iridium plugs, it is unlikely that switching to a different spark plug brand with a comparable heat range and design would make a noticeable difference in engine operation. Without additional information, perhaps your replacement spark plugs have an extremely wide gap that tests the limits of your presumably "stock" ignition system?

Quite some time now I felt that the suspension is a bit wobbly so I decided to replace all bushings and steering rods.
Did some shopping at W&N and also bought:
- front/rear discs with pads
- front/rear wheel bearings
- handbrake cables and handbrake pads
- steel coated brakes hoses
- radiator
- water pump, termostat
- visco clutch with new fan
- new clutch slave cylinder
- axle boot repair rubber
- driveshaft center mount and joint
- differential rubber mount....
I had an empty lift for a few days since my uncle who owns the shop went on vacation. Replaced majority of parts but still have to replace radiator, water pump, termostat, visco clutch with new fan and clutch slave cylinder and make wheel alignment,
Also noticed leak on the original front muffler. Since I already made a custom rear muffler, I decided to cut open the original one to see how internals are made and fabricate this one as well.
Got all the material and almost ready to put it together for test fit then weld it.

Only took a few days? You're a better man than me! 
I hope you removed the metal band from the flex disc at the transmission.
Not yet. Still stationary :/

Few days was like 5 days + 2 weekends and still not finished
I always use the 'few days' term to describe when I'll be finished.
Been doing it for 12 years now....

Forgot to add photos of finished exhaust
Last week I replaced parts that I had left from last year. Water pump, thermostat, radiator, and visco clutch with new fan.
Also did an oil service so it is ready for the new season.
I saw that the thermostat housing is a bit corded so I ordered a new one and will replace it next time when doing some maintenance.

I bought my 72 tii project when my son was 6. He's now 38 and it's still a shell.
Small update.
In March I attended a car meating. Decided to take e9 e30 and e24. Cleaned them the day before and went for a short drive with each.
Next day in the morning, e9 did not start. I didn't hear the fuel pump so I figured it might be the fuel pump relay. I shorted the pins and the fuel pump started working.
On the way there e24 died (no spark... still trying to figure it out to this day). Works okay until it warms up then it dies and starts normal once cooled down.
I got the replacement relay a lot smaller so I extended wires so I didn't have to break down the original connectors.
The meet with 2 survivors of the day:

looks great .... but hey, i like white cars
thanks, me too
my former e30 m3 was also alpinweiss. chamonix would have been an e9 choice ... just wanted a ceylon. i would like to have a chamonix e21 - 323i, preferably an alpina c1 or b8thanks, me too
Chamonix was used up through 1979.
oh that's right ... then alpinweiss 1. i had a friend who had a '78 320i in chamonix ... so i didn't remember that they changed the color
