FAQ
Find answers to your questions below.
Fitment & Compatibility
Check the vehicle, engine, part numbers, and fitment notes on the specific product page before ordering. If you need help, contact BTSCAR with your vehicle details and VIN. Have your installer confirm compatibility before fitting the part.
Requirements vary by product and vehicle. Review the listing for compatibility, included components, and installation requirements. Some conversion or performance kits need additional parts and ECU calibration; AFM/DOD delete kits require appropriate tuning. We recommend installation by a qualified technician.
