colder plugs

[stewmr2]

Hello all, just fitted the fensport pulley and blanked off the ABV valve with the metal plate - just have to sort the plugs now, currently car is running on Bosch super fours FR78X510 would these be ok??? or do I need to get different ones???

thanks Stew

Probably your best bet is to see what fensport offer as 1 colder and then see if that's the best price you can find them for.

change the bosch plugs, they are total crap IMO

NGK is where its at..
