[T-Bone Texan]

Thank you for the info

I now drive a 2015 Taco and it is by far the most complex peice of machinery I have ever operated.

There is a secret filter meant to prevent reverse release of gas fumes when the vehicle is turned off.

My goal in life is to find that filter and remove it; word on the street is that I can realize an increase of 2 to 4 HP.

The filter serves no other purpose.

You will find that mystery filter buried in your intake track. Dunno how your Taco is set up,

Look for a large clamshell type connection like for the airfilter. When you pop that off, you may see a large, flat black mesh looking thing.

That is the "hydrocarbon" filter. Mine was held on with plastic studs that had been melted over. After popping a few off, the rest gave up easy.

Power? I dunno, but felt better getting it out of there.
