OWNER NOTIFICATION LETTER

1982 & 1983 RX-7 Exhaust Emission Control System
Recall Campaign
Recall No. 23702

Dear Customer,

According to our records, you own a 1982 or 1983 model Mazda RX-7.

Tests performed by the Environmental Protection Agency (U.S. EPA)
suggest that Federally-certified 1982 and 1983 Mazda RX-7s may not
conform with Federal emission standards for exhaust emissions. To
correct such problems as may exist on individual vehicles, Mazda is
recalling them for free replacement of the catalyst pellets and
modification of the secondary air system. Neither of these operations
will affect your vehicle's fuel economy or performance.

Any Authorized Mazda Dealer in your locality can perform this repair
on or after February 27, 1987. We anticipate that the repair work will
require about one hour. We recommend that you call your Mazda Dealer
to make an appointment beforehand so as to minimize inconvenience to
you.

If you no longer own your 1982 or 1983 RX-7, please complete the
enclosed Change of Ownership pre-paid postcard and mail it to us as
soon as possible.

If you have any problem regarding this matter that is not resolved
by your Mazda Dealer, or by the nearest Mazda Distributor listed on
the Owner's Manual for your vehicle, you may wish to contact the U.S.
EPA's Manufacturers Operations Division at U.S. EPA - EN-340,
Washington D.C. 20460.

Please accept our apologies for any inconvenience to you over this
matter. We hope you will understand that we are conducting this
voluntary recall campaign so that your vehicle will continue to serve
you to your full satisfaction.

Sincerely,

CATALYST PELLETS & MODIFICATION OF SECONDARY AIR SYS
