1. Park the car on a flat, level surface. Set the parking brake.
2. Locate the oil pan underneath the car. The oil pan is located at the bottom of the engine. Slide a drain pan underneath the engine to catch the used oil.
3. Unscrew the drain plug with a socket wrench. The drain plug requires a 13mm socket. Allow all the oil to drain from the oil pan (allow at least 10 minutes for all the oil to drain adequately). Tighten the drain plug to the oil pan with the socket wrench.
4. Open the hood to access the engine compartment. Locate the oil filter cap at the front of the engine. It will be positioned directly in front of the oil-fill cap.
5. Loosen the oil filter with an oil filter wrench. Pull the oil filter out by the cap. Ensure you have a pan to catch the excess oil dripping from the filter. Pull the old filter off the end of the stick, using an old rag--this will prevent from making a mess.
6. Insert a new filter onto the stick, pushing it in until it stops. Insert the filter/cap back into the oil filter housing. Screw the cap tight by hand.
7. Unscrew the oil cap located directly behind the oil filter housing. Pour in seven quarts of engine oil. Pull out the engine oil dipstick located by the oil-fill cap. Wipe the dipstick clean. Insert the dipstick back in to the tube. Pull out and verify the level. The level should be between the minimum and the maximum marks on the dipstick. If the level is below either of the marks, add additional oil in half-quart intervals. Check the level each time you pour the oil.
8. Start the car up and allow it to idle for five minutes. Turn the car off and let it sit for an additional five minutes. Check the oil level once more. Add more oil, if necessary.
9. Log the number of miles driven and the date the oil change was completed. Reference this for the next oil change interval.

1. Open your hood and locate the air filter box and intake tube. Turbo models will feature a heftier intake that attaches to the turbocharger, while naturally aspirated engines have intake that attaches to only the throttle body.
2. Disconnect the electrical wiring, hoses and mass air flow meter that attach to the factory intake tube and set aside for use with the new intake system. Unfasten the hardware that holds the intake tube in place and remove slowly, careful not to spill any debris. If necessary, use a flat-head screwdriver to assist you in removing the intake tube.
3. Unscrew the bolts that hold the stock air filter box into place. Remove this factory intake box completely and dispose of it properly, as you will not need the filter or its housing box for the new install.
4. Check the new intake tube and count the number of holes that are drilled into the side. If there are more holes than hoses that attached to the old setup, plug the unnecessary holes with the grommets that came with your intake kit.
5. Attach the new intake tube to your A4 directly as the old one was removed. This part will mimic the old intake tube in design and functionality, while the filter itself will be positioned differently and provide better performance. Secure the intake tube with the silicone coupling that came with your cold air intake kit. There should also be a clamp ring that came with your kit to hold the silicone coupling and intake tube into place.
6. Attach the downward piece of the intake tubing system to the newly installed tube from Step 5. By this point, the intake tube should extend to the front of the engine bay and underneath the front of the car. The cold air will come in through the bottom of the front side of the vehicle, increasing horespower and fuel efficiency in your Audi A4.
7. Spray down the new air filter with the necessary lubricant before installing. Position the cone air filter that was provided in the cold air intake kit onto the downward intake tube. Tighten the clamp fitted around the cone filter to secure into place. Reconnect any remaining hoses and wiring that were removed at this time.
