My car had the 3 prong NGK spark plugs fitted and it ran fine, I swapped them to the OEM plugs and the engine also ran fine.
Interestingly the NGK plugs were slightly longer than the OEM ones, by maybe a few millimeters.
Anyway, would still suggest to buy the OEM spark plugs, they arn't very expensive.
Would also be worth flushing the coolant system and replace the coolant with OEM. I paid about £18 for 4 liters of concentrate from my local dealer.
Great video by a forum member on how to do that here:
