Title: Spark plugs
Post by: Zig star 2003 on November 29, 2018, 07:38:45 am

Hi
Is there any need for me to fit NGK iridium spark plugs if my Edition 30 is standard and if not can i fit NGK PRF7S8EG instead?

I'm sure you will feel a benefit from having fresh plugs of either model but given the similar cost why not get the iridiums?

Hi
Just that i had a set NGK PFR7S8EG that were not fitted to the car and i wanted to check mainly if they fitted and if it was worth getting the iridiums if i have a standard car and if it made any difference

They’re fine in standard cars.  Plugs don’t make any difference to performance but some people have to fit colder ones, or gap them if big tunes cause misfires.
