    Must-have for Toyota/Lexus hybrid EGR system service
    My wife's CT200h was due for the EGR service so I bought 2 cans of B-12 Chemtool to clean up the carbon. This stuff works! Saved me a lot of scrubbing on the EGR valve. I also blasted some into the small EGR passage ways in intake manifold to clean those out as well. Wife's car runs much better after all the work. This stuff saved a bunch of time and effort.
