At Imperial, we pride ourselves in our unequaled
success among local shops performing complicated
vehicle emission repairs.

Imperial has been performing vehicle emission repairs
since the inception of Illinois EPA testing in 1986.
During the years of IM240 testing we enjoyed more
than double the success rate of the next best area
shop performing emission repairs.

In October 2008 the State went to a "Report Card"
grading. In every quarterly booklet Imperial has
scored an "A", the highest repair score in awarded in
the state.
The current state report card can be viewed here:

Currently, after more than 25 years of emission repair,
we still boast an A rating with a 100% pass rate.
With a history of consecutive high scores on every
report, ASE certification and all of the latest
equipment, Imperial is the only right choice for
emission repair.
