Spark plugs upgrade for 156Hp

[Valex]

156Hp should use the NGK platinum PLZKBR7B8G 91530.
200Hp and 270Hp should use NGK iridium ILZKBR7B8G 97968.

I found them for almost the same price, can I use the iridium ones on the 156hp? Somebody test them already?

From the NGK website looks like they are an upgrade;

Will my 156Hp get 200 or 270Hp after the upgraded new spark plugs ?

Yes you can use them I’ve been running the iridium plugs in mine for around 6 years now but if you need more power go for a remap you’ll think you’ve got a different car!

Good, I'm going to order them !
I removed the spark plugs last weekend, just to check, they looks fine but I could not understand what for brand they are. Just to be sure, I'm going to replace them.

Don't ban me but in the end I went for the Bosch .
Bosch double Iridium 4047024277816.
I paid them 7.40 € each and free shipping plus after reading some review and watching some video I could not resist to try them .






A nice video to watch:

And this is one of the old spark plugs I replaced (no idea the brand)

This is turning out to be like the "What Engine oils" saga! We are lucky in that a computer can decide which works best & as the Z was built in Austria its a no brainer as to why it has Bosch this & Bosch that throughout the cars build my wiring is tagged with Bosch but its a PSA variant?
I agree with Neil as I have used NGK plugs in a variety of cars not all mine I might add & have found them to be bullet proof if the car is serviced properly so it comes down to the owners choice but if I was changing mine I'm tempted to try the Multi electrodes to see how they perform
