Motordyne M370 Intake Manifold Installed today. Install was a breeze, no point in a DIY really. They shipped me either one hose too short, or one too few hoses (either would have made it work), but I had some 3/8" ID hose here anyways, so I just cut some of my own. They also sent me a free Motordyne T-shirt, so it's all good
I will note one thing: if you don't have a bottle of Throttle Body Cleaner laying around, pick one up before you install this. You'll have the TBs off the manifold and it's an excellent opportunity to clean out any accumulated gunk with access to both sides of the throttle plates.
Took it for a short test lap around the neighborhood to make sure nothing was leaking, falling off, or throwing codes. All seems well. Subjectively, feels like I gained a little torque / responsiveness in the low-mid rpm ranges, which is exactly what I was hoping for. Nice job Motordyne
