Hi Kato, I'm glad to assist you. No, it doesn't. We don't have a direct-fit distributor available for the 1999 3000GT. We suggest checking the local part stores around your area on what they have available to offer you. I hope this helps, and we thank you for inquiring.

Hi Kenneth, I'm glad to assist you. No. This distributor is incompatible since it is a universal type of part. You should get a direct-fit part for your specific vehicle application. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, and engine size).
