Here is a 5-pack of turbo Dodge solenoid vent cap filters. These are used to help prevent dust and debris from entering and clogging engine management solenoids.
The use of foam filter solenoid caps is cheap insurance and will help prolong the life of the solenoid. Solenoid packs have been long since discontinued and good used ones are of course getting more difficult to find. These are also a nice finishing touch on your period correct and factory ‘appearing’ turbo Dodge restoration project.
Anyone that notices them is sure to ask...
"Fella, Like where did you get those solenoid filter caps?"
