管理機用の指定プラグです、正直プラグの性能は分かりません、送料込みの価格で決めました、信頼出来るメーカーなので心配していません。

The additional P/N designation (4000) is important since there is another plug with the same BM4A. The other plug has a longer insulator snout and should not be confused with the 4000 since it could cause engine piston damage. The NGK web site has detailed P/N listings for all engine and lawn mower models.
