should be fitting me RS plugs this weekend but was wondering do they need setting to a certain size gap or are they pre-gaped?

got mine this morning with a thump through letter box
any one know the correct gap for these as they may need re gapping
due to method of delivery

The ford plugs come in a box with a cardboard collar that protects the end of the plug.
there is no harm in checking the correct gap, I'm sure somebody will post the correct gap

think the normal gap is 0.7mm,when i fitted the new plugs i had them gapped at 0.5mm,purely because of the amount of boost i,m running.

Denboy - were you getting what sounded like a misfire at high boost, was this the spark being blown out, hence the reason for reducing the gaps??

thanks

you are correct,drove 30 miles home after my service and so far, seems to have cured it.

Cheers, I'll be whipping them out at the weekend then and closing the gaps up.

Unless you have a problem with misfires they will make no improvement to the performance! However they are a different heat range to the ST plugs so should prevent any problems with misfires/plug fouling occuring in the future!

In that case i would still get a set and fit them next time the car needs plugs! They are actually cheaper than the ST plugs!
