2008 STI Recalled for ECU Reflash - WVE-15 |

Service Program Bulletin#WVE-15
Bulletin Description: Subaru of America, Inc. (SOA) has determined that vehicles affected by this Service Program require ECM reprogramming. Under certain harsh driving patterns, specifically when repeatedly or continuously operating the engine above the "red-line" (RPM above 6,700), abnormal combustion could occur resulting in serious internal engine damage in the form of broken piston ring lands. This abnormal combustion condition is the result of an "over lean" fuel mixture caused by a combination of fuel cut activation and high turbo boost. To prevent this condition from occurring, Subaru has developed a modification to the Engine Control Module software logic that will improve combustion management above "red-line" engine speed. This revised logic will not adversely affect peak vehicle performance. |

'Hi Capacity' STi/WRX Intake Manifold
The Xcceleration Hi-Capacity STi/WRX Intake Manifold has a plenum which is about 6 times the size of the OEM plenum. The extra reserves of air stored by the large plenum allow the engine to take as much air as it needs even past the 7,000rpm redline. The Hi-Capacity intake manifold is designed to be used with tumbler deletes and a front mount intercooler.
The Hi-Capacity intake manifold is a must for big power applications, where you will need maximum air flow to support big power. |
