I think you might be mistaken in what spark plugs you have.. the part number matches the regular Laser Iridium spark plugs.. and the one step colder NGK come in different packaging.. just a heads up glws

 

I'll do some research. However, I bought these from B2autodesigns. They were listed as one step colder which I somehow missed while ordering. In addition, the plugs came with a invoice listing them as "stock heat plugs for STI, Legacy GT and Genesis 2.0t." I also spoke with Charles from B2 when I realized what I had ordered and he too confirmed this. Again, ill look into it and confirm what they are. Good looking out though, thanks.

 

the plugs for certain year sti's also fit in the vq35de and are in fact 1 step colder since it is for the turbo sti model. But you can get the ngk iridiums 1 step colder from an auto parts store for said around 54$ at most.

 

Yes the basic Iridium IXs are about $20 cheaper but these are Laser Iridium Premiums, they are marginally more.
