N63B44O0 Spark Plug Gap

Aussie_550i · 12-28-2021, 09:33 PM

Hi all,

I've searched the interwebs and haven't really found anything definitive answer on this topic.

A few people have said 0.030 - 0.032 and some one else said they run 0.022 but their fuel economy all but vanished

.

My engine is stock, but exhaust is factory downpipes with cat, then 2.5" to a single muffler at the rear.

Not after a power gain, but just want new plugs gapped correctly.

Any help is greatly appreciated.

Thanks.

IIRC 0.032" is the correct gap for stock N63. 0.022" is usually set for tuned motors.
