Show original supplier description
The STM Evo 7/8/9 Street Intercooler provides a functional and more affordable upgrade for street-driven Mitsubishi Lancers from 2001-2006 (Evolution VII, VIII, IX). It features a 3.5" Vibrant core with an 875 HP flow rating, though STM suggests it for applications up to 800 HP, recommending their Race Core for higher outputs. The intercooler is constructed from Tig Welded Aluminum with 2.5" bead-rolled pipe outlets and has been pressure tested to 50 psi. Installation requires trimming or removing the factory crash beam and is compatible with the STM Front Bumper Support. It does not fit the Cusco Power Brace. Couplers and clamps are sold separately. STM products are made in the USA and this intercooler comes with a Lifetime Warranty on STM Parts against manufacturing defects for the original purchaser.
