Application:
0.9 BAR: Common on many older and some newer Japanese vehicles, especially from brands like Toyota, Honda, Nissan, Mazda, Mitsubishi, Subaru, and Lexus, used in models from the '80s through the 2000s for engines that don't require high pressure, fitting small, standard-style caps and often found on models like early Civics, Corollas, Sentras, 4Runners, and CR-Vs. Always verify by matching part numbers (like Toyota 16401-63010) or checking your current cap before buying, as pressure ratings are crucial.
