Chainging spark plugs and air filter on Sportster

Spark Plugs = Champion RA8HC (Champion makes Harley spark plugs. They are basically the same. It was only $1.49 per plug at Auto Zone.)

5/8 spark plug socket (or like I did, just use 5/8 wrench. Harley's plugs, just sit there, not down in the hole like other bikes.)

There is nothing special about changing them, just pull them out and put them back in.

Air Filter =
HD 29331-04 (They are really proud of their air filter around $30.00 + tax.)

3/16 allen wrench will let you take off the air filter cover. Then you need T25 Torx Driver to take off the air filter off the body.

My bike only has 5000 miles on it, but the air filter was FILTHY!!!!!
