My current ride is a 2004 Cooper S with JCW Tuning Kit # 3387

I just bought a new MSD coil, MSD Spark Plug Wires, and NGK Iridium IX (BKR7EIX 2667) Spark Plugs from Madness Motor Works and I was assured that this set up will work fine with the JCW Tuning Kit.

My question is can I run the new set up with the NGK Iridium Spark Plugs (BKR7EIX) versus the standard NGK Spark plug that they recommend when installing the JCW Tuning Kit..... BKR7EQUP ?

I know that the MSD coil runs a higher spark or hotter, will the NGK Iridium IX (BKR7EIX 2667) Spark Plugs work with out doing any damage?

Do I just need to go back with the BKR7EQUP?

Has anyone done this set up as well? MSD coil, MSD Spark Plug Wires, and NGK Iridium IX (BKR7EIX 2667) Spark Plugs ?

 

The EIX's will be fine, they're a plug with apparently a longer service life, and on here somewhere is a chart with heat ranges I think, that shows the Iridium as a tougher material that has more resistance than copper or silver etc. I use them, not on a JCW, but with 250chp, standard coil and leads.

 

I appreciate the feedback. I went ahead and installed the EIX's and an MSD coil/wires. I also installed a K&N air filter too. The Mini seems to be running fine, but I think I need to reset the ECU.

Reset ECU........WOW !
