Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Shoshop Intake Manifold ?

Gotta question for anybody with knowledge of this: i'm thinking of buying the Shoshop 37mm secondary butterfly manifold and 37mm extrude honed intake manifolds. Do you think it's worth the money they are charging for them and worth the performance?

The reason i'm asking is because I can still pull of my car under warranty with these mods right? No biggy.

37mm Secondary Butterfly Manifold - $229

The Secondary Butterfly Manifold is opened up 4mm to allow more air into the engine. Performs best when teamed up with our 63mm Throttle Body and ExtrudeHoned Manifold. Expect a 5 HP gain on your 2.5L or 12 HP gain on a 3.0L Conversion. Exchange, $300 core.

ExtrudeHoned Intake Manifold - $349

We open the secondary ports slightly to match 37mm plates. Exchange, $300 core.

The biggest problem is that Sho-Shop decided that it's not worth it to provide this service to the customers. The will still do the lower and sned out the upper for you, but you have to give them your equipment, and wait 6-8 weeks in order to get it back. Knowing sho-shop's reputation, that 6-8 week wait could take much longer.
