Spark Plug Question

[erokkin]

I wanted to do some preventative maintenance and change my spark plugs at 12K miles which is coming shortly. I purchased NGK 94201 Spark Plug for BMW B48/B58 engines package from Burger tuning. My question is, the product description says Gap - Factory Preset: 0.030", we suggest closing gap to .022" for tuned applications. Since my car is stock, should I still be gapping down the sparkplugs to .022 like they say for better performance/reliability in tuned cars or just leaving them at the factory gap?

Thanks. Eric

Nope. If you’re stock and staying stock gap to .030.
