We use B-G Products for throttle body/air intake/fuel injection services. It's the best we've used. The primary fluid services we do are brake, power steering, and transmission. For brakes we use a Snap-On machine, for Transmission a T-Tech, and for power steering a "generic" machine. They all work well. The best machine is the one between the service advisor's ears that explains the need to the client. Today on one van we did the power steering, brake, coolant, and fuel/intake service. Helps the vehicle.....raises the ARO......gives the tech satisfaction of doing a thorough job.
