Ignition coil Denso or Bremi

Denso coils are good for another 150,000 miles

If you want to aftermarket

DENSO 673-3204 is best

Grab some Denso coils from Rockauto. Shouldn\u2019t take ten minutes to swap them. The locks on the plugs are about guaranteed to snap (if they\u2019re even still on it), don\u2019t panic, just plug them back in and don\u2019t worry about the locks. The four 2AZ Yotas I own and the 3MZ Sienna have been just fine without them.

‘03 540i original Bremi coils still rockin at 152k mi

Stock Bremi/bosch are the way to go.

I got the Denso from Amazon it wasn’t cheap but you don’t want misfires with after market cause the car will idle and drive like shit.

Ive had mine misfire all of a sudden, whole car shook, CEL lit up, said code "cylinder 1 misfires" sometimes it ran normal but then rough again. If i gave more than 1/2 throttle it shook even more and it had no power at all. When i checked the coils on mine they were original "BREMI" manufactured and even the date from back in the day was on the bremi coils. They now held up 230000 kilometers since when the car rolled off the factory, thats more than enough service

I’ve never had an issue with my Bremi coils. Just replaced the suppression tubes. M50/M52 coils very rarely fail. Just the tubes.

I used Denso coils on my 2016 2.5L SE and they are literally the Ford coils with the Ford number crossed out and a sticker slapped on to cover most of the number.

Bremi had premature failures in the first few years of the e46 and were replaced as OEM by Bosch.
