1. Warm up the engine by taking a small drive or letting idle for 10 minutes.

2. With car running, open hood and locate the two vacume lines leading to the intake manifold.

3. Take container of Sea Foam and pour 1/2 the bottle into a empty bowl or bottle. I used a dry and empty water bottle. Now you will not be needing the sea foam container any more.

4. Cut a strip of vacume line or whatever you may wish to use.

5. Attatch to the front intake bung.

6. Lean vacume line into bottle, but do NOT submerge it in the sea foam.

7. With hand on the throttle body, or someone in the driver seat, raise RPM's to 2500rpm and hold.

8. With engine at 2500 rpm tilt the bottle of liquid and VERY slowly let the end of the vacume line touch the sea foam. If the engine begins to choke you are doing it too fast and need to stop so the engine can stabilize.

9. Continue this until 1/2 the liquid in the bottle is used then let the engine go back to idle.

10. Remove the vacume line from the bottle but DO NOT shut of the engine.

11. Reattatch the vacume line to the front intake bung.

12. Locate the rear intake bung that leads to the FPR.

Turn off the vehicle and let it sit for 10 minutes.

17. Start vehicle and watch the smoke ploom out the exhaust... there will be a lot.

After 5 minutes:

18. Let sit for 15 minutes or until very little if any smoke is still exiting out the exhaust.

19. Go for a little drive allowing the RPM's to reach 6000 rpm. Smoke will continue to exit the exhaust for ~2-5 minutes but will eventually stop.

20. You are now done and enjoy your car.
