After a code 71 I am trying to trouble shoot the problem, want to the booster and found that the filter is clogged with dirt and crap, the manual says to blow it out with air, it is not in great condition and would not servive a hard cleaning so................what to use as a replacement filter? Toyota does not have a replacement filter for this and can only offer to replace the entire unit for $60 some dollars. This is probably not the problem but at least a place to start
