Es lo que buscaba, compatible con mi auto

I just installed these coils this morning and they are working great so far. I had misfires, acceleration problems, etc. and after replacing with these coils, it runs perfectly. Will update in 6 months if I remember.

Great price worked well and easy to install. My cars a 98 Buick LeSabre. It definitely after a little bit of time worked. I read how people thought the part looked cheap looked fine to me for the price of $30 that's $10 a fix. My advice if your a d.i.y Do it yourself guy just make sure you need to replace the coils if you have good spark plugs and wires make sure all of that working well and ignition control module among other things. If you feel you need them have extra to keep in trunk for when it does go bad. If yours aren't bad, I recommend buying all three if they are oem coils on your car or never been changed. For my car use a 7/32 size screw and 1/4 ratchet. Should be the same for most Buicks. Also like another person did definitely write down the correct firing order no big deal. My only regret was not having it sooner if that was in my budget lol

So far. So good. Tip for GM 3800 series 3 V6 engine users: Make sure to put a thin layer of dielectric grease on the metal plate the two bottom coils sit on. It will act as a heat barrier and make the coils last longer. See pic. Note: The top coil (for some reason) sits on a raised up area so the grease is not needed.
