Spark Plug questions (1 Viewer)

Run from the Bosch Plugs, their quality has gone down over the years. There have been many reports of poor performance and electrodes breaking off. The final hint to me, was when BMW went to NGK for most OEM applications.

Platinium plugs will last 60k in the 80 series without problem. After careful research, I went with the Denso PK16R8 plantium in the original heat range from sparkplugs.com (about $7 each)

Yupp, the orig. plugs from my 2002 530i were NGKs - should have learned then

OK, the Fusions are on their way back to Kragen's
