Installing the URO Premium Intake Manifold Repair Kit typically requires removing the manifold from the car. Follow the standard shop procedures to remove the manifold.

Remove the original central plastic vacuum actuator by carefully prying off the push nut, unsnapping the actuating rod with a flat bladed tool from the central pivot lever, and carefully disconnecting the single vacuum line.

Next, use the flat bladed tool to remove the left and right metal flap connecting levers from the central pivot lever.

The pivot lever is now accessible to remove the central bolt using a T30 Torx bit. We provide a new pivot bolt as these tend to strip easily upon removal.

Install the URO Premium quality aluminum central pivot lever using the newly provided pivot bolt noting the correct orientation. It is recommended that a small amount of silicone grease be put on the bearing shoulder of the central pivot bolt and blue medium strength thread locker be put on the mounting threads. Tighten the central pivot bolt to 7 to 8 foot pounds and review.

Put a small amount of silicone grease onto the ball studs of the right and left connecting levers and snap them into place on the central pivot lever.

Install the new URO Premium vacuum actuator onto the locating guides and push on the newly provided push nuts. Reconnect the vacuum hose to the upper canister body.

Next lightly grease the central pivot lever ball stud and snap the actuator rod onto the central pivot lever ball stud.

The newly repaired and upgraded manifold is now ready for re-installation into the car. Make sure all fault codes are cleared upon completion.

The intake manifold needs to be inspected to ensure no excessive carbon deposits are present on the intake swirl flaps themselves. This could lead to binding and inconsistent operation even after the repairs and enhancements are completed. A simple cleaning with common intake aerosol cleaners is recommended anytime the manifold is serviced.
