Not to hijack your thread, but I have a 2002 that is scheduled to have the spark plugs replaced on Tuesday.

I use the NGK plugs and when I get home shortly, I'll get you the number.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

From the factory they use: Beru Model#14FGR 6KQU
I cannot find any info on these anywhere?
Does anyone have any idea on how to cross reference these with the NGK Iridium plug part#'s?
(As i recall, most beru plugs were copper, yes?)
Not to hijack your thread, but I have a 2002 that is scheduled to have the spark plugs replaced on Tuesday. I thought the correct spark plug was FGR 5 KQEO; however, the mechanic told me that the OEM spec is FGR 6 KQC...that is what he is putting in. Does anyone know which is correct or if it matters if I go with either?
My indy mechanic, whom I trust, told me that my 2000 Cab should have the new spec plug when the originals were replaced at the 30K check. He states that my car now operates under the 60k plug change interval .... if I so desire.
Generally, a boosted engine will use a cooler plug because of the increase compression in the cylinders. So, the TT using a cooler plug than the NA engine is right. However, many TT owners still run the FR6 plugs.
REMEMBER that the NGK plug heat designation is the OPPOSITE of Bosch. The lower the number, the HOTTER the plug.

What plugs would you suggest for my nitrous application? I was probably going to stick with copper and go one degree lower. Do you think it would be necessary to run one heat rating lower or should i just to it to err on the side of caution.
The name is Jim, and yes I would stay with copper and go one heat range lower. After running awhile, look at one of the plugs and you'll be able to tell if they are too cool (not cleaning themselves) or just right. Although Nitros is a cold application, it will greatly increase combustion chamber temps as does forced induction. You MAY find, that the standard heat range will work fine, but I would rather go a safe route first and then back up to the hotter plugs if necessary. There is not a great difference between a #5 plug and a #6 plug anyway.
