Other than OEM plugs which are very costly what else do you guys suggest?? i have an 07 550i

 

OEM Plug was only 8 bucks per. You can get the same plug minus the BMW Logo for a fraction of the cost. Both NGK and Bosch are OEM. Whatever you do, just don't buy them from the dealership. They wanted $25 a plug.

 

where did you find them for 8 bucks a piece? even the bav.Motorsports wants 22 dollars a piece what they do offer a Bosh for $12 for my car as well

 

Look on amazon.

 

Check out Xpress Auto Parts from Amazon.com. I've just paid $53.94-shipped for six NGK Iridium spark plugs tonight.

 

550i OEM spark plugs are Bosch FR7KPP332
Check Amzon you can get them x8 for $80

 

Thanks guys AUTOHAUSAZ had them for $8.40 each cheapier than amazon did (at the time I looked) ..now going to do it myself let's see how hard it is lol didn't look to bad except driver side rear one

 

Mine were 18 each at Autozone with discounts for my 535. I would stock up at 8 bucks a piece!

 

I was told my 08 550i uses 4294 NGK Laser Iridium Spark Plug. Part# IZFR6H-11 These are long life plugs and i plan on changing mine soon.

 

Just to let you know... Removing the last coil on the passenger side is a PITA... You can also even break the coil or damage it. Watch out with it and buy loads of patience.
