Not Denso. The seal is improvement over flat seals used by other brands, but the bottom shell has only 6 holes vs 8 for YZZD3, should be flat for optimum capacity and anti-drainback function... All TRD had to do was direct Denso to produce a housing taller than YZZD3,.install YZZD3 style filter element, use 8 or perhaps 9 holes - but elongate them.oval as does Ford to increase flow.
