STM Stock MAF Intake Pipe | 2003-2006 Mitsubishi Lancer Evolution 8/9 (EVO-INTK-MAF)
The STM Stock MAF Intake Pipe Kit is designed for your VIII-IX running the factory MAF sensor and will adapt to any stock-style blow off valve. The pipe will free up power and let your 4g63 breathe while giving your intake a bit more aggressive sound. New design fits both Evo VIII-IX with or without ACD.
This comparison was done on our Mustang Dyno to a mainly stock 04 Evo with 120,000 miles (Walbro 255, Hallman, test pipe & ECU flash). Nothing was altered between runs. Max increase in HP was +13 and the graph shows increases from 4,000 rpm all the way through... right where you want it! Gains can be expected to be higher with more air flow and boost, of course.
