Want to talk about tangible results?
This is an intake manifold BEFORE and AFTER performing a BG INDUCTION service.
You can see all the black carbon buildup in the before photos...... that was clogging the EGR passages. This effects the drivability and performance of your vehicle.
After the service the intake is LIKE NEW.
I love it when the results are easily identifiable.
When was your last induction service performed?
