Could someone please tell me what BI and BL mean for Mazda. I have to purchase two front wheel wheel bearings and it’s a 2013 model Mazda 3. But I’m not sure weather that BL and BI is anything important when ordering them🙏🏻Julie

  • There's not enough information to answer your question @Julie, what are BL and BI in reference to? Is it in a part number, or some other form of identification? Please be more specific. – GdD Sep 5 '18 at 9:12
  • These are different "generations" (Mazda's term) of the car. BK was manufactured from 2003-09, BL 2009-13, BM 2013-16, BN 2016-present. But I have no idea what "BI" would be, unless it's a typo Anything earlier than the BK wasn't a "Mazda 3". – alephzero Sep 5 '18 at 9:45
  • If mine is 2013 model would I then purchase the BL or BM? – Julie Sep 5 '18 at 9:51
  • The BM was actually the "2014 model" even though it was launched in mid 2013, so a "2013 model" should be a BL. – alephzero Sep 5 '18 at 9:51

These are different "generations" (Mazda's term) of the car. BK was manufactured from 2003-09, BL 2009-13, BM 2013-16, BN 2016-present.

I have no idea what "BI" would be, unless it's a typo. Anything earlier than the BK wasn't a "Mazda 3".

The BM was actually the "2014 model" even though it was launched in mid 2013, so the OP's "2013 model" should be a BL.

  • Good answer. Basically, if the OP wants to order parts, just using the year of the car should get her what she needs without worrying too much about the "BL" or "BM" designation. – Pᴀᴜʟsᴛᴇʀ2 Sep 5 '18 at 10:24
  • That's one advantage of a national car registration system like the UK's. Just type in your registration plate number, and the garage or parts supplier knows exactly what car you mean. Much easier than figuring out whether it makes a difference whether it's the GL, GLS, LS, LX, or some other weird model designator! – alephzero Sep 5 '18 at 11:39
  • In the US we use the VIN for specific model identification. Many auto parts stores/dealerships/insurance companies will look your car up by the VIN. Unfortunately, a 17 digit code isn't easy to remember or transcribe. – Tim Nevins Sep 5 '18 at 13:12
