Since 1963, Crown Automotive has been providing outstanding quality replacement parts for Jeep vehicles. That same quality and experience can now be found in our new line of accessories, as well as heavy-duty & performance components, called RT Off-Road.
Easy to install, though mounting screws could be longer. Do not overtighten or you will strip the plastic they thread into. Maybe a noticeable gain in throttle response. A little power maybe, nothing huge.

I gained a gallon of gas per mile after installing. Couldn’t really tell in power but there was slight improvement in gas mileage.
