Decent kit, but a few quirks
Overall, the tune-up kit is good, and it has all the necessary parts for my 7.4 V8. However, I found the instructions a bit unclear at times, which made the installation take longer than I expected. Once it was all set up, though, the engine runs great now!

Not the best experience
I bought this kit thinking it would be a straightforward install for my 5.7 engine, but I ran into a few issues. The cap wasn't fitting quite right, and it took a couple of tries to get everything sorted out. Eventually, it worked, but I expected better quality for the price.

Perfect for My Thunderbolt Ignition Setup
This tune-up kit was just what I needed for my MerCruiser with Thunderbolt ignition. All parts were included, and the spark plug wires were a perfect length. The engine runs much smoother now, and I'm really satisfied with how everything turned out!

Solid Kit for My Engine Tune-Up
I recently used this tune-up kit for my MerCruiser 5.7, and it worked like a charm. The spark plug wires are high quality, and the distributor cap fit perfectly. My boat's performance has definitely improved since I made the switch. Worth every penny!
