replacement element which is taller than standard may not be
used to hold the air cleaner cover open. No other components of
the air induction system may be removed, replaced or modified.

14. STREET TOURING CATEGORY

E. The engine management system parameters and operation may

standards for the year, make, and model of the car. These allowances
also apply to forced induction cars, except that no changes
to standard boost levels, intercoolers, or boost controls are permitted.
Boost changes indirectly resulting from allowed modifications
are permissible, but directly altering or modifying the boost
or turbo controls, either mechanically or electronically, is strictly
prohibited.

15. STREET PREPARED CATEGORY

Cars running in Street Prepared Category must have been series
produced with normal road touring equipment, capable of being
licensed for normal road use in the United States, and normally sold
and delivered through the manufacturer’s retail sales outlets in the
United States. Cars not specifically listed in Stock or Street
Prepared Category classes in Appendix A must have been produced
in quantities of at least 1000 in a 12 month period to be eligible for
Street Prepared Category.

A vehicle may compete in Street Prepared Category if the
preparation of the vehicle has not exceeded the allowable
modifications of Stock Category, except as specified below.

considered the same.

15.1 AUTHORIZED MODIFICATIONS

allowed.

B. Street Prepared vehicles may only be modified in excess of Stock
Category rules in the following ways. Any modification not
specifically authorized by the Stock Category or Street Prepared

hood scoops or holes necessary for carburetor clearance).
Structural modifications, such as the addition of members known
as “jacking rails”, are not permitted unless specifically authorized
herein.

15.10 ENGINE AND DRIVE TRAIN

4. Turbochargers and/or superchargers (“forced induction”) may
not be added, changed, or modified. On vehicles originally
