Probably fits newer Troopers as well. This is K&N part number 33-2064 and
has been used for under 12K miles. I saw between 1-2 mpg improved gas
mileage after installation and the vehicle did seem to have better overall
performance. Sold the Trooper so I'll sell this for $30 shipped anywhere in
the continental US. Comes with box, stickers and manuals. Email me if
interested as I do not check this board often.
