This listing is the kit only — the price does not include installation or tuning. We can install and tune Roush systems at our Marengo shop, or tune many combinations remotely; those services are included in our packages, or available separately.

Want it installed? Our technicians can install it at our shop in Marengo, IL, and we tune it on our in-house chassis dyno, by appointment. Street tuning dials in drivability.

Not local? Many Mopar and Ford combinations can be tuned remotely with HP Tuners.

Submit a work request and we'll confirm fitment, install and tuning for your car. Shop rates are listed on our Rates & Terms page.

Lead time depends on the manufacturer and on our shop schedule, so it varies by part. If you need something by a certain date, contact us before ordering and we'll check current availability.
