Mitsubishi Lancer Evolution (2003–2015) · Intercooler upgrade
Is a Intercooler upgrade Worth It on a Mitsubishi Lancer Evolution?
Short answer · Depends
A larger or more efficient intercooler cools charge air on turbo/supercharged engines so denser air reaches the engine, especially on repeated pulls. For the 2003–2015 Mitsubishi Lancer Evolution (Evo VIII/IX (2003–2006 US) and Evo X (2008–2015)), Helps hold power when heat-soaked; peak gains depend on boost and tune. On a mild stock-boost car the difference can be small in cool weather. Typical cost: Typical $400–$1,200. Difficulty: Moderate–advanced. Confirm local rules and warranty impact before you modify the car. This page is general guidance—I am not claiming a personal install on every Lancer Evolution kit listed in search results.

Is a intercooler upgrade hard to install on a Lancer Evolution?
Moderate–advanced. Budget about 2–6 hours. If you are not set up for DIY work, get a quote from a shop that knows this chassis.

In the US a modification alone does not void an entire vehicle warranty, but a dealer can deny a claim for a failure they can show the mod caused. Keep stock parts.
