Stainless Turbo Manifold for Mitsubishi Lancer Evolution (2008-2015) 2.0L

High-Flow Equal-Length Stainless Turbo Manifold for 2008-2015 Mitsubishi Lancer Evolution (CZ4A)

What it Does: The Stainless Turbo Manifold replaces the restrictive cast iron factory manifold on the 2008-2015 Mitsubishi Lancer Evolution to optimize exhaust gas scavenging and reduce turbocharger spool time.

The Stock Mitsubishi Lancer Evolution Exhaust Flow Restriction

The factory cast iron manifold on the CZ4A Evolution X relies on an unequal-length log design that causes severe exhaust pulse interference prior to entering the turbine housing. Under repeated track abuse and elevated boost pressures, the brittle OEM iron casting is prone to thermal fatigue, cracking at runner junctions, and warpage across the cylinder head mating surface. Furthermore, the cramped, rough-cast internal passages create high exhaust gas backpressure, increasing cylinder temperatures and choking high-RPM volumetric efficiency.

The Engineering Solution

Constructed specifically for the 4B11T engine platform, this tubular ram-style manifold features 1-5/8 in. (42mm) equal-length runners manufactured from Schedule 40 304 stainless steel with a reinforced 3mm wall thickness. The equalized primary runners ensure uniform exhaust pulse arrival times at the turbine scroll, accelerating spool and increasing mass airflow across the powerband. A heavy 1/2 in. (13.5mm) laser-cut head flange is hydraulic-press leveled to guarantee a leak-proof seal against the head. Hand TIG-welded seams maintain joint integrity through aggressive heat cycles, while the factory-pattern TD05 flange provides a bolt-on interface to replace OEM part number FE615310-31.
