OOOhhh My Goodness!... This coil woke My motor up as if it was a "Sleeping-Giant" waking up from a Power-Nap! I'll be ordering the other 7 in a few mins. I had #8 cylinder misfire... Not Anymore! Lol!

These were the needed fix for my slightly tuned 135i that was suffering from misfires at increased boost levels! Perfect fix!

Still less than half the price of most local auto parts stores with a lifetime replacement — you cannot go wrong!

There was a misunderstanding between myself and FCP when it came to these coils. FCP actually reached out to me to address my issue and get the problem solved quickly. I can't edit my original review but yes I would recommend these coils.

The price is better than going to an auto shop and spending double. You get a warranty with them as well. Well worth my money.

They work just right

While I'm in AZ, my spouse in TX called and reported a rough engine. Code showed misfire on cylinder 3. It was the coil pack. Super easy to swap out; just remove engine cover, unplug, pull and insert.

A common culprit of misfires. Same part as OEM, FCP has a video on it somewhere.

Jan 2020: 2006 X3 at 82,000 miles, first time plugs and coils were changed. The combination was a revelation. The car is much faster off the line and it actually changed the transmission shift points somehow, in a very positive way. I didn't put any dielectric grease on the coil per the FCP video. One trick that I came up with to really seat the connector 100% is to use an open end wrench to gently push it all the way in. Use the flat side of the wrench as it straddles the connector. You can push down the top latch and not really be all the way in with the connector. I didn't like that, so this worked out well. Try it.

Did not "seat" into valve cover on my April 2006 330xi. Don't fit! Maybe Delphi will??
