Yes, the ride will be smooth, but sluggish -- watch the RPM's. The ride will be much, much smoother -- not saying you need it. Watch your gas mileage still -- that will tell you. The part costs $170 on-line. And it takes 10 mins to install, literally. My mech. charged me $40 to install it -- that's how simple it is. Watch it over your next fill ups or if it is pulling like something is stuck in the engine -- it's needed. If not, it will go soon. They work together!
