The cylinder heads on your car engine are where air, fuel and spark all come together to create a controlled explosion that is part of the internal combustion process. One of the side effects of these explosions is carbon, which can build up on the inside of the cylinder heads and potentially rob the engine of horsepower. To fix this carbon build-up, pour in an engine cleaner treatment.

Pop the bonnet. Locate the vacuum line running to the brake booster on the driver's side of the firewall. Pull it off of the brake booster by hand.
Start the vehicle. Put your assistant in the driver's seat while the vehicle is idling. Pour the engine cleaner treatment slowly into the vacuum line while your assistant revs up the engine to about 2,000rpm. Empty the container, then turn off the car and let it sit for 10 minutes.
Start the car and drive it for two to five miles, or until the white smoke goes away. Aggressively work the throttle but drive within the limits of the law.
