The plug for Passo 1KR-FE is (2010-onward) NGK Iridium IX LFR6AIX-11 . There might be other compatible plugs as well. Please note that parts are somewhat different for post mid 2014 Passo, as Toyota made some changes to the engine.
I could not find the genuine part no cabin filter for Passo in the market but found out that Toyota Corolla's cabin filter fits the passo as well.
