    Coils: Delphi or Bosch? Other?

    125K motor. Runs quite strong on the original coils. But they have been baked for 17 years here in South Florida. A new set, plus plugs does not break the bank. I figure I'll change them out pre-emptively and have six known good ones as spares.

    So, New Delphi part number, old Bosch part number, or other choice?

    I have been off the forums for quite a while. Apologies, since I know this must have been asked and answered. But I don't see any answers in my searches.

    I've been running the Delphi on cars without any known issue, but I suspect I'd say the same about the Bosch too.

        Any thoughts on the new Dinan offerings?

        I am looking to buy a spare set as well, figured on Delphi or Bosch but for the same $ or less in some cases I see these new fangled Dinan "N Series".

          I went with Eldor a few years back. It seems the e90 guys had a very good experience. Either way I would buy from FCP strictly for the lifetime warranty.

              fits our cars. I can get six for $155.99 just South of me in Miami from a vendor I have dealt with for years.
              Glad I asked. I poked around and looks like Eldor seems to get the highest respect. Thanks everyone.

                I didnt spend a lot of time, but I could find nothing tangible about these except perhaps they are rebranded coils from the same vendor that supplies BAVAUTO. I would avoid them.
                I was all set on Delphi until I found out in this thread about Eldor. I have decided to go with Eldor coils. Thank you to all who posted in my thread. Very helpful!

                    I'm going with the Eldor "273's" as well from FCP just because I like my spare parts and after reading reviews those also seemed like a great choice. I have no doubt the Delphi's or even Bosch coils would have been fine as well though.

                    Now I just need a spare motor or spare car, my OCD runs deep.

                      Actually the Eldor coil number is R3516S00100 for our cars. I bought six and six NGK Laser Platinum DCPR8EKP.
                      Going to try to install all of them at 9AM after I get off work (night shift).
                      Been using partscontainer on eBay lately for the best prices and fastest shipping. Their customer service guy (if I need one) I deal with is Jason. Solid guy.

                      EDIT: Install was a huge success. Going to start a thread how great this combo works.

                        What are people's thoughts on NGK coils?

                          FCP has the Eldors on sale for $22.59 each (usually $28.19)

                            NGK is quality though I've not seen anyone run them.

                              tl;dr version
                              Are Eldor and BBT the same?

                              long version
                              I ordered six Eldor coils from FCP, and they only sent one (in a very plain white box). They shipped the other five without any hassle, but they sent boxes marked as BBT.
                              Before I contact FCP, are the BBT coils the same as Eldor? Thanks
