iridium spark plugs
Discussion
Anybody tried Iridium plugs yet? The theory sounds good!
Couldnt find anything about B7EC plugs on the NGK site
so couldnt find the iridium equivalent.But after an hour of searching i came up with a cross reference chart on the Denso site. So i thought i'd pass it on.
They cross ref NGK BPR6ES plugs with Denso IW20 plugs.
Anyone tried them or found the NGK equivalent?

This is the reply from NGK -
Dear Sir
NGK Spark Plugs still manufacture B7ECS, we have plenty in stock.
Any NGK stockist can order this part number for you the stock number for
the plug is 2528.
I hope that this helps with your enquiry.
So ill just hang my head in shame and stand in the corner
