I ordered a set of 4 sensors for my IS 350 (build date of January 2006). I told them I needed PN 42607-30030 due to my pre April 2006 build date.

The sensors they shipped me have the following markings on them:
PACIFIC
>PA66-GF30<
0430811121

FCC ID: PAXPMV1017
IC :3729A-PMV1017


Individually, they have these numbers below the "0430811121":
DDB8045
411B096
8B3F107
D43B0D0

Here is what they look like:




I thought they would have 42607-30030 stamped somewhere on them but no dice. Are these markings correct for my application?

Also, where is the best place to order the valve assembly/bushing kit?

I've read I should get a silver valve assembly to avoid a galvanic reaction.

Thanks,
