Show original supplier description
The Mitsubishi 1545A001 is a Genuine OEM factory replacement blow-off valve, specifically sourced from the 2006 Lancer Evolution IX MR. This metal valve features a stiffer spring compared to the original plastic stock Evo valves, making it a direct and significant upgrade for Evo 8 and DSM models. This air by-pass valve is constructed from durable metal, ensuring longevity and reliability. Users have reported that replacing a worn-out or leaking aftermarket blow-off valve with this OEM part resolves issues such as car stuttering during acceleration and improves overall engine performance under boost. Applications for this valve include the 1996-2006 Mitsubishi Evolution IV, V, VI, VII, VIII, and IX models, as well as the 1995-1999 2G DSM vehicles, including the Eclipse GST/GSX, Talon TSi, and Laser Turbo. The OEM part number is 1545A001, with a Mitsubishi reference number of 11728.
