I was excited to get the RPS distributor cap and the spark plug wires, but the ignition coil stopped working after just a few uses. The rest of the kit seems fine, but I expected better longevity. Could've been a fluke, but I'm not happy.

Great upgrade for my boat's engine
I installed this RPS Thunderbolt 4 distributor cap and rotor kit on my MerCruiser V6, and the improvement in performance is noticeable. The MR43LTS plugs included are a nice touch; they fire up my engine like a charm. Highly satisfied with this set!

Good quality but installation wasn't easy
The RPS kit seems solid and made my engine run better, but I struggled a bit with the wiring setup. The instructions were not super clear. Once I got it done, though, it worked like a dream. Just be prepared for some trial and error!
