Default Spark plug change interval on (FBO+) N54? - 12-02-2019, 04:49 PM

In general, how often should I plan on changing the spark plugs in my FBO+WMI stock turbo'd n54?
(The plugs and coils were replaced about 30 months ago, iirc)

Thanks,
// Radar //

I don’t think there’s a “set” time interval- a lot depends on plug choice, gap, etc.

I guess I’ll throw up a ballpark # range- 8-10k?

Well...
Iím way overdue then. Iíve put about 38,000 on these.

Iím FBO+WMI usually casual but ďspiritedĒ commute driving, I.e. no hard core or track days. Florida, 26 miles each way to work, etc.

Do you have a recommendation on plugs and gap?

*I attempted to log a 3rd gear pull to post but I think I ran out of room on the JB4 log storage area. Last few logs werenít saved.

Thanks,

Thanks. Yeah, 1-colder or 2-colder is the question. I feel like Iím somewhere in the 1-1/2 colder range, lol. I run Meth but only 50/50 boost juice, so I am not sure if that truly qualifies.

I think Iíll do the 97506 based on the recs.

Thank you for the responses!
