    Rated 5 out of 5 by from Nice, nice piece. Really nice piece - 5 stars for overall quality and fitment. Haven't got it 'wet' yet but I do not foresee any leaking. The only recommendation I would have is for a second o-ring groove just inside the existing one to 'press' the thermostat itself tight to the intake - not to seal it, but to keep it from being loose, which it is when the housing is bolted down tight...at least it is on the Edelbrock 7577 intake I'm using. The stat is just the slightest bit 'loose' under the housing, and while I cannot imagine that would affect cooling it still bugs me, so I'm going to sandwich a square cut o-ring on top of the thermostat to keep things nice and snug.

    Rated 5 out of 5 by from Great upgrade from the stamped steel I installed it on a Fi air gap intake as I didn't want to put the steel one on that would've rusted, it looks great though you'll never really see it other than the base and feels like a quality part and is light

    Rated 5 out of 5 by from No more leaks This is a must have for a magnum engine to replace the poorly designed factory stamped steel housing .

    Rated 5 out of 5 by from Works great Been fighting a leak at the housing since engine install, finally decided to take a deeper look into it and realized the M1 intake required a special housing, not just an OEM magnum style. Picked this up based on part numbers, swapped it on and it has done its job. My only negative is that I waited so long to do this.

    is this housing cut to accept the thermostat? or does this housing require intake to be cut for it?
