You might want to have some needle nose pliers ready to pull them out. I like the blue shop towel type. The ignition is now prepped. The ignition cables are wrapped in a towel and then a plastic supermarket shopping bag. Just use the handles from the plastic bag to tie it up.
Same procedure applies for the ignition rotor.
Pull the plastic snap on cover, towel and bag. Clean the racing filter as directed by the manufacturer. With the wheels off the car you can hit different parts of the engine that otherwise would be inaccessible. This side shows the tranny casing. Engine covered in Foamy Engine Brite.
