### ⭐⭐⭐⭐⭐ As spark plugs go....
*by C***L on January 27, 2011*

These worked very very well. In both my 1998 BMW 323is [M52 IIRC] as well as my 2001 525iT [M54] they went in just fine and the cars both ran without a hiccup after install. Replacing the OEM NGKs in the 5er, and Bosch plugs in the 3er. \o/ no check engine lights!
