Features & Product Details
If you are going through the perils of rebuilding the 4B11T, you will want to use the right type of piston that can sustain high-performance driving conditions where boost is increased, or where you might be using the vehicle for racing purposes. With that said, Cosworth has developed the 87MM 9.2:1 compression ratio piston that has been manufactured through the same careful forging process that is involved with the pistons developed for Formula spec applications. This is a complete piston set that comes with premium rings that have been built to reduce friction and to reduce blow-by. Also included are a set of premium wrist pins, and finally, these pistons have Cosworth's anti-scuff skirt coating with polished tops.
