NGK coil packs Summit Racing NGK U5055(24H20
Iridium spark plugs (BKR6EIX) Rock Auto NGK 6418 Gap 0.032
BMW 11617534237 hot weather CCV.

My parts recommendation. I've run almost 30k+ miles on the coils and spark plugs. No issues at all. I think a hot weather CCV separates oil vapor better. Less oil usage through the CCV system.
