Remove emission control valve on the side/sides where you want to perform the cleaning. The plastic tube tends to stick to the valve, take care not to break the plastic tube during removal. Note: If your vehicle has over 100,000 miles as a rule we recommend replacing the valve during the cleaning because the diaphragm gets stiff and will also restrict the air flow into the cylinder head.


If you are reusing the emission valve, clean the exhaust side with carb cleaner and brush. Ensure the valve does not leak and that it opens in the direction of flow by blowing through it.


Clean aluminum tube from both sides with hand brush and carb cleaner until tube is clean, bend brush as needed.Note: After using the brush to clean the pipe out you will see how the carbon is removed from both ends and the part is much cleaner.


Clean hole in back of cylinder head. Insert tube in hole so O-ring is making a seal.


Insert funnel & fill with cleaner. Some cars the cleaner will sit in funnel, this depends on how plugged the system is. Repeat this step 2-3 times and allow cleaner to sit approx. 20-30 minutes each time.

WARNING: Remove ignition coils and spark plugs from the bank you are working on, this is to prevent hydro locking the engine with cleaner fluid.


REMEMBER SAFETY GLASSES! Use air blower with rubber tip. Hold steel tube firmly into head, blow compressed air into steel tube. A popping noise may be heard from carbon plug in passages blowing out.


Install brush on cable & tighten. Insert cable with brush into AGA guide tube. Insert brush & tube into cylinder head.


Insert funnel into handle, spray cleaner into funnel. Connect drill to cable.

Note: Run drill clockwise ONLY. Counter clockwise can cause brush to loosen & fall off. Start cleaning passage, the funnel will help guide the cable.

After the cable is fully in, remove the funnel & continue cleaning until cable has reached the bottom. Spray more of the cleaner and continue cleaning for approx. 5 minutes. Remove AGA tube & cable.


Insert AGA tube, flush with more of the cleaner. Blow in tube with compressed air. Air should be heard coming out at exhaust and some cylinders. Turn engine over min. 720 degrees. Assemble engine. Start engine & run for minimum of 10 minutes. Run secondary function test to verify that it passes. Reset fault codes in system.

What is the average repair time?

The repair time will depend on how bad the car is plugged, but typically we estimate 5 hours for 1 bank and 8 hours for 2 banks.
