So I have a 2009 prerunner 4.0 v6 (2wd) and I bought a UP107 uni filter for the secondary air filter and I regretfully ordered before checking but I don’t see the filter under the hood. Are the 4x4 models the only ones with the secondary filter? If not, where in the world is mine located

2012-2015 has the secondary air pump. I think all the 2nd gen 4cyl have them
