Spark Plugs

[pitucas]

The spark plugs i have fitted on my 155 Q4 were Bosch WR6DTC (3 lateral electrodes), the recommended ones!

But i wan't to change them. I've discovered that they are discontinued. They were changed by Bosch to WR6DC+ (just one central top electrode).

Anyone of you is using this last ones?

Or are you using another ones? Wich ones?

My Q4 is using a KN filter (box replacement) and a Squadra chip besides a direct 3' exaust ...

What spark plugs do you recomend???

I use the NGK reccomanded from Evocars {sorry I do not remember the code type} and a friend of mine with Squadra's chip mounted use them too with no problems. When he had mounted on the Q4 he noticed a + 200 rpm in idle and corrected it, that's the only problem he had. My idle with OEM eprom was at 1150 rpm.
