Sorry if this has been mentioned before,

Currently I'm looking to get a new o2 sensor for the B18C Type R.

I went on NGKs website, and only o2 sensors for the B18C2 and B18B2 popped up, none for the Type R, on the part finder:

I rang up NGK Sydney today, and the guy over the phone had no clue if they are compatible.

Can somebody please clarify?

Thanks
