I bought my MRS 3sgte again in 2020. Parker from NW Motor s known as me and informed me I was obtaining a 1-of-a-type, cleanse 3sgte motor. and he didn’t lie. I’ve bought the photos to confirm it in advance of installation. I haven't observed a motor this cleanse. Seems like it just came off the assembly line.Acquired 3rd B16B swap from J&Jmoto
