At the dealer yesterday to pickup a couple of items and inquired about plugs. Twenty dollars a pop! Lately, I've been replacing OEM parts with non OEM that have better performance and pricing; i.e. Akebono brake pads, Zimmer rotors, future Bilstein shocks. I believe a lot of Bimmers use NGK plugs, so I checked their website but nothing comes up on plugs for 28i. Bosch shows two different plugs for the 28i. Checked with ECS Tuning and they show BMW OEM, NGK and Bosch.

Has anyone tried the non OEM Plugs? If so, experience.
