(Bosch) spark plugs noise reduction

At the moment i use the denso ik20 in my 1zz fe turbo (gt28rs at 10 psi)
I want for the summer 1 step colder. I can Go for the ik22. But what About this ones:
https://au.bosch-automotive-shop.com/en/products/details/-/productdetails/0242245571

Gap 0.7 mm vs 1.1 for the ik20 (ik22 And ngk 7 has 0.8)

Are the bosch spark plugs a good idea?
The look simelar to the densos

Thanks Andres

I was asked about these earlier this week. I did some testing with these plugs a couple of years ago. From a simple plug swap I picked up 10 whp. You can get a set of four for the price of one iridium plug. The design of the plug is what I think really does the trick. The recessed design keeps the electrode out of the combustion area.

Agreed 100% :thumbup: ^^^

well i know there are some rare bosch plugs in the past, but this one look simaler to the denso iridium power and NGK IEX series.

i will buy new springs for the hatch from that site, so i save on shipping cost.

Spark resistance And noise

Well we all know that the ignition system create a lot of noise.
The denso's And ngk have a resistance of 5k ohm. If this resistance is higher say 6 k ohm would this affect the creation of noise?

I did Some research And i think you did this test on the oem ecu not on the power fc. Is that right?

I think it was on aem ecu during the time when he was greddy supercharged and running gas.

You need to do some more research then, I haven't run a stock ecu in a long time. Mind you, I did not change my tune when I swapped to these plugs and picked up ten wheel HP.

?
The reason i thougt that was that the V-power plugs don't have resistor (mostly 5 kohm). Sparks with no resistor have a better ignition but create more EMI (Electric noise). Today only non resistor plugs are used in old car or racecars (with minimum electronic devices).
The oem ecu can handle noise much better dan the power fc. Thats why i thougt that. And new plugs perform always better than used plugs.
So often it looks like one plug is better than an other but its because one is new And the other is used.

But my question was jf sombody has expercience with these bosch plugs.
The have platinum And iridium And a gap off 0.7mm (now i have 1.1 (oem))
And a resistor of 6k instead of 5k used by denso And ngk.
