Just be careful of the sinter iron clutches as the dust is magnetic and collect over the crankshaft position sensor over time and can lead to your P03XX misfire codes. If you have these kind of clutches it is good to pull out the CPS every few oil changes and clean it off and just do the relearn if you have the X4.

Here is a picture of someone that was throwing misfire codes with the clutch dust attached to his CPS.

What is a sinter iron clutch?
How to tell if you have one?
Specs?

It is just the clutch compound. You have your organic compound clutches like the RST, and then the sinter iron compunds like the RXT. The sinter iron clutches just as a nature of the design grab hard and can hold a lot more torque which is why you see them in these high HP applications and are favored more so than the organic compounds.

I believe the Spec Stage 2+ does not have an iron compound clutch, but I am not positive. I think they start with the metallica in their 3+ and up clutches.

Yep... What he said. SPEC 2+ worked for me too in conjunction with the MGW RaceSpec shifter.

Sintered is using powdered metal that is form by heat and compression rather than something that is casted and machined.

You are right!!
