2008 535i spark plug
 

So I am going to change my spark plus on my 08 535i and saw that they take Bosch super plus. I was wondering if anyone has used the Bosch platinum and what their thoughts are or if it would be better to stick with the super plus? Thanks!

Hi,

Bosch recommends using OE spec plugs to avoid any issues.
Here is the link for the OE plug:

AutohausAZ - Bosch spark plug

Use the OE part, either BMW or Bosch. The only difference aside from the logo on them is the price (go figure). Make sure you get the right socket.

Got a misfire the same day I put JB4 on the car. It had been giving a slight misfire when cold before JB4.

Use the OE part. Some people have used the platinums and had issues with misfires.
NGK also makes a good plug, but for the price I would stick with the OEM spark plugs.

The NGK would be a waste for you unless you are running a heavily modded N54 engine. Go with the oem Bosch plug.
