BMW N54 IGNITION KIT

I got these coils from PRW and they have been a great investment. As your plugs wear outside the gap tolerance your coil has to work harder and harder to fire across that gap. This means more heat and more demand on the coils internals. Eventually the coils fail and the dresser misfires come out to play again.
These coils are super robust and very closely matched in sets to within a couple ohms! Which is pretty good! They have the ability to do a longer dwell if your tune requires it but not recommended on stock cars running stock fuel you could burn a piston or an output stage in your ecu worst case scenario. Anyway they are great because they continue to perform amazing even when your plugs are worn way out of tolerance because they produce so much energy they jump that 40 thousandths gap that was supposed to be a 30 thousandths gap but you being mean to your ride didn’t change plugs at last service.
I love em Because they kick ass! I noticed an immediate difference in response, crisp snappy throttle response now. Smooth idle and. No break up even on raised redline tuned cars like mine putting out substantially more than oem! Definitely worth the money! Ask anyone who has em. I’m trying to see if I can get em to work on my ms43 pencil coil e39 because they look cool as shit too! Definitely have that race car appeal to them- 100%! I’d buy em again! And you can buy them one at a time in the rate likelihood one should fail or you damage it( more likely than it actually failing because they are so robust) GET Em! You won’t be disappointed
