I'm ordering coils for my car. Last time I bought Direct Ignition coils for $46/each. But now I'm showing on the same website (partsgeek.com) that they have "Ignition Coils" for my car (2008 135i coupe) for $40 as well as the Direct ones.
What's the difference? Can I buy the cheaper ones or do I have to use the Direct Ignition coils?
Thanks!
