Bosch Coil Boot Replacement

So Im about to place and order with BMA parts for a bunch of stuff and need to make sure Im ordering the right coil boot part. My car is a 9/02 330ci that has had the ignition coils replaced under the BMW recall. It currently has Bosch Coils. The coils look like the one in the attached picture. I looked on Pelican Parts and BMA and the boots they sell for Bosch coils do not look like the one in the picture. RealOEM says 12131740477 is correct up til 10/02 but the picture on that site looks different that the picture of my coil. BMA and Pelican Parts also show pictures that look different than what I have installed in my car. Since the coils were installed on a emissions recall, maybe the coil boot is different? Im not sure if they are even replaceable.

Anyone know what part number to order for coils replaced by BMW emissions recall?

Thanks

I hate to be a buzz-kill here, but why are you replacing the boots?

These are not usually a preventative maintenance item, they should last the life of the car. They don't last the life of the car as a practical matter, but to replace them for no apparent reason is generally considered to be a waste of money.

My car is a '94 with the original boots (as far as I know). Your car is ten years newer and has the coils replaced under some sort of recall, so your boots should be about 1/4 the age of mine.

Unless you have a known problem that you are certain comes from the boots, I'm not sure you need to replace them. I'd not replace them unless I had a positive indication of a malfunction.

Nice, E46fanatics as usual, ask a simple question, get totally unrelated answer. (Thanks for not using the words stupid or idiot like some members do)

Maybe because you used to change spark plug wires back in the day? Maybe my valve cover leaked over the years and the residual oil around the spark plug degraded the rubber? Maybe I want to change them just because its Tuesday, No wait its Friday. Maybe I want to change them just because I want to. Does it really matter?

BTW, I allready changed my cooling system, and my struts arent worn out because i rebuilt my entire suspension a few weeks ago.

So now that we got all that behind us, are the boots on this coil replaceable? If so, what is the correct P/N to order? The ones listed for 9/02 look completely different than what was installed in my car under recall.

Thanks

If you're referring to that pic you have in your first post, the answer is no.

I guess my point is that you can save a few bucks if you leave well enough alone.

If you insist on going broke, you need to visit the local dealership.

Go to AutoZone and have them look up your car coil pack, I was surprised they had mine in stock, and they are all the same.

These are what failed boots look like





Compared to new

If I were you I'd go Craigslist hunting for some good used ones. Perhaps I was lucky or just happen to live in the right region but I found a guy who owns a used car lot by Oakland. He also buys wrecked cars and parts them out. I got ignition coils for all 6 for $120 and he threw in the OEM plugs that were also in great condition. Now my coils were the design prior to the ones you have. I swear.... he still has his ad for all 6 of th types you have that also look brand new for same price.

Would failed boots cause misfire?
