I have one strut bar in stock at the moment, I'll have more for summer!
Honestly I have no idea what brand the yellow wires are, I pulled them off my 94XR2 for new ones before I sold it. They made their way onto my red car as it didn't come with any. I can look in another week or two once the snow has melted enough that I can pull her out.
For stock engines I like to run either the cheap copper plugs or single electrode platinums. Don't run the +2 or +4's they're junk. If you've got the $$$ the Iridiums are nice and low maintenance.
The blue hose connects to a boost controller, more boost = more power
