just seen a set of ngk iridium plug on ebay for £26, is this a hotter or colder plug and do i add these if i am upping boost. sorry for qstns - i am still learnig
Stick with NGK PFR7B. I have not had them fall apart. I have suffered a broken insulator that took out a cylinder head with HKS Iridium and know of others with similar failures around the same time.
qstns - i am still learnig
, i take it the insulater is the piece around the base of plug in cylinder. thanks for warning mate
