wilkorangerover Posted May 17, 2009 Author Share Posted May 17, 2009 (edited) NGK Iridium - BKR8EIX sounds good to me Edited May 17, 2009 by wilkorangerover (see edit history) Quote Link to comment Share on other sites More sharing options...
dan4 Posted May 17, 2009 Share Posted May 17, 2009 Why do you want iridiums so bad?! Rob BKR8E havnt been available for quite a while now, guess the spark plug FAQ needs updating. The equivalnets are the NGK BCR8ES i now use Previously used BKR7E Quote Link to comment Share on other sites More sharing options...
RobSheffield Posted May 17, 2009 Share Posted May 17, 2009 It probably does need updating, i just copy pasted to make a point Quote Link to comment Share on other sites More sharing options...
