Performance, great prices and customer services that you can trust. When J-Spec Tuning was formed we wanted to provide the highest level of performance parts and advice with the greatest integrity. To that end we start by carrying products that meet our high standards and are all backed by strong manufacturer warranties (minimal one year). Secondly, we stock virtually every item that is in on our site. Lastly, we just make sure our customers are taken care off. Any issues with products are quickly resolved and installation advice provided by experts that probably install that item at one time.

When you purchase from J-Spec Tuning, you are purchasing products with the piece of mind that it will be delivered in a timely manner and perform as advertised. We also provide installation services if you are in the San Francisco bay area. Our installation address is
