How many pistons do I need to order for my Honda B18C5 engine?

The Honda B18C5 engine typically uses four cylinders. Since this piston is sold individually, you will need to order four of these pistons to complete your engine build.

What is the advantage of a forged aluminum piston?

Forged aluminum pistons are stronger and more durable than cast pistons. They are better able to withstand the higher pressures and temperatures found in performance or modified engines, while also being lighter which can help with engine balance and responsiveness.

Can this piston be shipped to California?

No, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Wiseco is well-known for making strong internal engine components, and this custom piston for the Honda B18C5 is no exception. If you're building or rebuilding the engine in your B18C5-powered Honda, this piston is designed to meet the demands of a custom setup. It features a specific 85.50mm bore size and a +3.1cc dome volume, which is crucial for tuning compression ratios in performance applications.

This piston is made from forged aluminum, a material chosen for its strength and lighter weight compared to cast alternatives. This means it can handle the stresses of higher performance use while helping to reduce overall engine weight. The dome shape is specifically designed to work with certain cylinder head configurations to achieve your target compression. It's important to note that this piston is sold individually, so you'll need to order the correct quantity for your engine.

Because this is a custom piston, it's intended for builds where specific performance goals are being targeted. Always refer to your engine builder's specifications or your tuning guide to ensure this piston is the right choice for your compression and displacement targets. Please be aware that this part is not CARB approved and cannot be shipped to California.
