I’m really pleased with the RPS tune-up kit for my MerCruiser 8.2 V8. The quality of the parts is impressive, especially the distributor cap. It’s been running smoothly since I installed it. Definitely a worthwhile investment for any V8 owner!

Decent but had some issues
The RPS tune-up kit was pretty solid for my 7.4 V8 engine, but the installation instructions could have been clearer. I figured it out eventually, but it took longer than I expected. Still, the parts seem well-made and improved my engine's performance.

Great Kit for My Boat's Engine
I recently used the RPS tune-up kit for my MerCruiser 5.7 V8, and I'm really happy with the results. The spark plug wires fit perfectly, and the distributor cap was a breeze to install. My engine runs so much smoother now!

Perfect for Thunderbolt Ignition!
This RPS tune-up kit worked wonders on my 5.7 V8 engine with Thunderbolt ignition. Everything was included, and I loved how easy it was to install. My boat is running like new again!

Not impressed with quality
I bought this tune-up kit for my 5.0 engine, and I was disappointed when the spark plug wires started fraying after just a few uses. I expected better durability given the price. Wouldn't buy again unless they improve the materials used.
