If the letters (for example BKR-EIX) indicate the spark plug shape and thread size, the numbers (from 6 to 9) indicate the heat range, basically meaning how well the spark plug can operate in intense conditions. The higher the number, the more the spark plug will be cold and more adapted to tuned engines and sporty use. A cold spark plug is designed to operate at higher than average temperatures and disperse the heat inside the cylinders, improving combustion, performances and engine reliability, reducing the risk of detonation. However, make sure you only fit cold spark plugs if your car requires them, otherwise you could encounter problems such as difficult cold starts and rough idling. Also, do not install cold spark plugs if your engine runs on E85 fuel. In short : BKR6EIX : standard grade, for standard engine and standard use or E85 fuel BKR7EIX : one grade colder than standard, for lightly tuned or sporty engines, used both on the road or the track BKR8EIX : two grades colder than standard, for tuned and powerful engines used mainly on the track BMW 3-Series E30 : 316i, 318i (M40, M42, M43) BMW 3-Series E36 : 316i, 318i, 320i, 323i, 325i, 328i (M40, M42, M43, M50, M52) BMW 3-Series E46 : 316i, 318i, 320i, 323i, 325i, 328i, 330i (M43, N40, N42, N45, N46, M52, M54) BMW 3-Series E9X : 316i, 318i, 320i (N45, N46) BMW 5-Series E28 : 520i (M20) BMW 5-Series E34 : 518i, 520i, 525i, 530i, 540i (M40, M50, M60) BMW 5-Series E39 : 520i, 523i, 525i, 528i, 530i, 535i, 540i, M5 (M52, M54, M62, S62) BMW 5-Series E6X : 520i, 525i, 530i, 540i, 545i (N62, N73, M54)
