Mazdaspeed 3 2.3L 2007 - 2013 DISI Oil Baffle Kit

Removing the crankshaft balance shaft assembly from the 2.3L DISI engine frees up rotating mass and helps to improve engine response. However removing the balance shaft assembly alone can cause oil starvation issues during high G load corners and extreme driving because of the void left behind in the oil sump. Simply installing a balance shaft delete alone can lead to engine damage in certain conditions due to inadequate engine oil pressure.

The Cornerstone Oil Baffle Kit includes an engineered baffled oil sump insert developed by Cornerstone racing engineers it  features oil passages and diverters to maintain oil supply around the oil pump pick up. Also included with the kit is the specific balance shaft delete hardware.

Validated under extreme conditions, is perfect for track day use or other hard driving conditions. Oil pan not included. 

• CNC Laser cut aluminum plate

• CNC Aluminum/Steel balance shaft delete assembly

• Can be installed with engine in car- oil pan/sump not included.
