Quick Temporary Spark Plug Query

[jezza16v]

Hi, pre '90 8v digi. was only running on three cylinders, found No1 plug to be duff, the only spare I have is for a '90 1.6 driver we used to have, the throat length is the same as the one taken out so I put it in and it runs fine now but I'm just wondering if I'm safe to run it any distance with this plug in while I get a new set sorted?  The only difference I can see is that the new one is a champion and has three contacts whereas the one I took out is a bosch with 1 contact

Nope wont be any trouble.. The 1.6 just ran cooler spec'd plugs which are more optimal for starting and running and warm

That's a relief! Thanks for your prompt reply
