CP Piston & Ring Set for Toyota 4AG 16V - Bore (81.5mm) - Size (+0.5mm) - CR (9.0) - Single Piston

CP Pistons is known for making strong internal engine components, and this forged piston set for the Toyota 4AG 16V engine is a great example. If you're rebuilding the heart of your 4AG, these pistons are built to handle the demands of performance driving. This set is 0.5mm oversize, meaning it's intended for engines that have been bored out to 81.5mm to refresh the cylinder walls.

These pistons are forged, which means they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, making them a solid choice for engines that see regular use or are built for higher performance. The 9.0:1 compression ratio is a common target for naturally aspirated builds, offering a good balance between power and drivability. This set is designed as a single piston, so you'll need to order the correct quantity for your engine.
