Part#: srt6IMtweaked

We took a set of stock SRT6 intake manifold / plenums and went to work on them. We started by removing the restrictive inlet tubes and professionally TIG welded in new mandrel bent inlet tubes and formed them into the box properly. We add a 1/8" npt bung to both the passenger and driver side inlet tubes to be used for a boost gauge (plugs will be included if you don't use them). The manifolds are then professionally internally ported and then teflon velocity coated inside and out. The lettering on top of the manifolds can either be left coated or semi-polished upon request. The finished manifolds were then sent to the flow bench. The factory drivers side intake manifold flows 255-260cfm @ 28 In. of H2O
Our tweaked drivers side manifold flowed 330cfm @ 28 In. of H2O

Note: above numbers were from one manifold, together these should be able to flow 660cfm!!!!!!

These manifolds do not flow nearly as much as our NeedsWings full replacement intake manifolds, these are a less expensive alternative.

These manifolds were designed to be used with our NeedsWings Cold Air Intake systems and have not been tested with the factory air box or 55amg air boxes but i believe we have very good chances of clearing without issues. I will update this description as soon as we get someone to test fit them with a stock or 55amg air box.

Teflon velocity coating colors include silver, dark grey (pictured above), black, red, yellow, green or blue. please specify your color choice in the "special instructions" section at checkout.

These are made to order, please expect a 2-3 week lead time.

These are made on a core exchange basis. There is a $500 core charge for us to send you the new set before we receive your original intake manifolds back. This core charge will be added to the "shipping" charges at checkout. The $500 core charge will be fully refunded once we receive your original intake manifolds back to us in good usable condition within 30 days of delivery of your order. You must protect the gasket mating surface from being damaged. If you just throw them into a box without proper packaging they will be destroyed and you will not get your core charge refunded. Show them the same love that we showed your replacement manifolds please!

A set of our NeedsWings Intake Manifold Gaskets are included.

We have seen +20hp and +20ft/lbs of torque with these over the factory manifolds.
