High flow ported factory 85.5-89 2.3 Turbo lower intake manifold. Lower intakes are ported and rounded for increased flow. Should be used in conjunction with a ported upper intake.

Custom made to order, can take a week or two to ship depending on status of core, difficulty in welding certain cores, etc. 

DO NOT SHIP CORE BEFORE HEARING FROM US OR CONTACTING US AS CORE DOES NOT SHIP TO OUR LISTED ADDRESS.

Core Charge Terms:
If you're unable to ship your core until after we send the new intakes, or want the new intakes to ship while your core is still in transit, or want to wait to ship to core until you get the new intake, you'll need to pay the core charge during checkout. Then when we receive your core (within 30 days), we'll refund the core charge back to you, minus payment processing fees. A core charge is required if you don't have useable cores to send in exchange for the ported versions. We can also port your intakes when necessary (if they are painted, powder coated, etc.). The returned core must be the same style intake as we ship. You can't ship an inline style 1983-84 intake, or a dual plug 1991+ intake in exchange for the 4 square 1985-1990 style intake pictured.
