Relentless Customs' Intake Manifold is an OEM Mazdaspeed 3/6 intake manifold that has been ported, polished, and powdercoated.

During the porting process, the runners are tested for balance between pistons 1/4 and 2/3, the VTCS system is removed and associated mounts are removed and shaved down. Manifolds are properly powdercoated and the OEM vacuum connection for the brake booster is replaced.

The COBB AccessPort is required to delete check engine codes P2006 and P2009.

Manifolds are custom-painted to order and may take up to 3 weeks to ship.

Please note that a core charge of $200.00 will be added to your order. Your original intake manifold must be returned within 30 days of delivery, in good condition, for this $200.00 to be refunded.
