Colder spark plugs required. Help?

[ben_r1]

Does anybody know where i can find colder rated spark plugs for the 197 engine?

For reasons i cant say i need colder plugs to help run a modification. Looked on all the main sites for hours ( NGK, Bosch etc. ) with no success.

Surely all the turbo 172 boy must have to run colder plugs?

Thanks for any help.

if you're using NGK, just change the number from a 6 to a 7 or 8 BCPR7ES or BCP8ES will be perfect

use the ones i've stated TBH, i've used them in a wide variety of cars. They're cheap and they work perfectly every time

BCPR8ES????

Will the fit into a 197 engine?

yes. depends what boost you're running, and how cold you're going though dont go colder than you need, you may coke the plugs up during gentle driving. It will clear if you do, but you'll get a bit of a hesitation until it cleans itself up.
