Steeda has just developed an insert for our hugely popular 2005-2009 Mustang GT cold air kit. This insert allows you to run your factory tune and 87 octane fuel. No computer flash is required!! The best part is it still produces up to 10 hp and 10 ftlbs of torque to the rear tires with 87 octane.
This is perfect for people who daily drive their Mustangs and would like an increase in power but not have to run premium gas regularly. Or for those that only want to run performance tunes at the track as the insert can be easily removed or installed.
Please Note: only compatible with 555-3120, 555-3131, 555-3131-B.
