YSK catalytic converter thieves are targeting specific models of cars (especially the Prius). Toyota is so back-ordered on catalysts it may take over a month to replace a stolen one, while costing you over $1,000. But theft can be deterred by installing an anti-theft catalytic converter shield.

YSK催化器竊賊的目標是特定型號的汽車（尤其是普銳斯）。豐田公司的催化劑訂單非常多，可能需要一個多月的時間來更換一個被盜的催化劑，而花費的費用超過1000美元。但是，通過安裝防盜催化器防護罩，可以阻止盜竊行爲。
