Request help - quick spark plug question

[Guest Michael Derby]

I have an '04 LeMans Nero Corsa. What is the stock # of the NKG Iridium plugs? Does anyone know - and do most Auto Parts stores stock them or do you think they are special order?

 

Also if I replace them with standard OEM Plugs from my dealer instead what is the correct gap?

 

Thanks in advance if anyone can help!!

Mike, myself and everybody I know considers iridium plugs something akin to snake oil. There's just no credibly justified reason for 'em in Guzzi's. The NGK BPR 6ES is OEM, it's what I run, it's what everyone I know runs. They typically read moderately sooty on the flame-shadow side. This is normal. Gap 'em per shop manual spec at .028", or .7 mm. If your A/F ratio is anywhere near reasonably set up, you can go 10K miles (some even double this) without even looking at 'em.

 

Hope this helps.

And they are cheap enough that you can replace them every valve adjustment

For what it is worth, here are some cross refs that MAY work (double check that the heat range is correct):

NGK iridium BPR6EIX

NGK Double Platinum PGR6B

NGK GP platinum BPR6EG

ND iridium IW20

Splitfire Platinum TP6C

Champion RN9YC

ND W20EPR-U

Totally agree! I looked into "magic plugs" and came to the conclusion that they were all hype. I'm on my third set of NGK BPR 6ES plugs with nary a complaint.

Thanks for the info. Its getting around that time for a new set of plugs. All though it seems to me that piston is running a little rich. last time I checked it was almost completly blacked out and smelling of gas.

 

 

I think its time for a PCIII
