I notice my car running a little rough so I checked the distributor cap, rotor and spark plugs for sounds for excessive wear. And as you can see, it was time for a replacement. So I went to the Porsche dealer to see what parts I needed and how much they cost. THEN I went to eBay because I’m not stupid. LOL. So when the parts arrive 8 months later, I put them on. I didn’t change the ignition wires because they measured around 3k ohms.

I bet she runs real good now… and you can sleep a lot better at night knowing that your baby is well tuned. 😉
