I have been debating doing to the IMS retrofit since I bought my early 2005 model 997 C2 earlier this year. Tonight I finally got around to changing the oil since it had been ~6 month and 5k miles since the last one. I found minimal amount of metal shavings in the old oil filter when cut/inspected. Although the mount of metal shavings was not significant, it was enough for me to go for the LN IMS retrofit.

Any recommendations for shops in the sac/bay area? I live in Davis, so Sac area is preferred, but I can travel if needed. And what is the typical price range for such a job? thanks!
