RS tuner & new spark plugs

[mattfarina]

Is it worth upgrading the plugs when using the RS Tuner maps?

I've heard iridium plugs or NGK coppers (BCR8ES) might work well with remapped 1*2's.

Anyone tried it or had any results?

Personally i'd stick with what Renault recommend .

NGK PFR6E -10

 

[skini]

no need to upgrading plugs
i tried some others and NGK PFR6E are just fine and last well

Ive done this and loved the results, feels like a much better car before 5k.

I used Denso iridiums and the difference was instantly obvious, much sharper throttle response.

Do it you know it makes sense.
