Replace coil packs or not?

    2011 328i xDrive 6MT with 119,000 miles. Bought car 2 years ago with 112,000 miles. Runs good. Depending on what you read it looks like plugs should be replaced every 60,000 miles? If so, I'm coming due. Wondering if preventative replacement of ignition coils when I do the plugs is a good idea or a waste of money? And, are the Bavarian Autosport "High-Performance Ignition Coils" a good idea? Coils for this car range from BAV standard coils at $18 each to BAV High Perf. coils at $45 each to BMW OEM at $82 each. Thanks!

    I am certainly no expert and don't know how your motor differs from my 1996 2.8 with coil packs that are more than 200K miles old. :)

    My philosophy is, if it ain't broke, don't fix it.
    Sure it's preventative. So is replacing the cooling system or replacing the battery every few years.

    I thought I'd heard that was initially the case with the turbo N54's but then there was an upgraded coil design. Not sure if N52's had the same thing or are/were the same coils.

    The N52 original coils are very problematic. So its up to you to replace them now or wait. If your a do it yourself person than I would wait until they start to fail to get your moneys worth. As for which to go with BMW has updated they coils to a new manufacture which has solved most of the issues with them. As for upgrading to the high performance ones I don't really see a need since you are not modifying your vehicle that would require a high KV spark.
