The West Coast Fiero High Performance Roller Rockers (Roller Tips), with a ratio of 1.6 to 1, are designed to enhance the performance of your Fiero’s engine. They achieve this by increasing the valve lift, which is the maximum distance that the valve opens from its seat. This allows more air to flow into the combustion chamber, leading to a more efficient combustion process.

One of the significant advantages of these rockers is that they achieve this performance boost with minimal impact on smog emissions. This means that while you’re getting more power from your engine, you’re not significantly increasing the amount of pollutants your vehicle emits. This is particularly important in regions with strict emissions regulations.

The increased valve lift can help boost the horsepower output of your engine, whether it’s a stock engine or one that’s been modified for performance. Horsepower is a measure of an engine’s power output, and increasing it can lead to improved acceleration and top speed.

These West Coast Fiero High Performance Roller Rockers (Roller Tips) are versatile and compatible with multiple engine types. Specifically, they can be used on 2.8, 3.1, and 3.4 engines. This means that regardless of the specific engine model in your Fiero, you can take advantage of the performance benefits these rockers provide.
