Default Motormite 615180 3800 Intake

Is anyone having good luck with this particular replacement intake. Its description on Advanceautoparts.com says that it is a reinforced intake and GM direct replacement for the 95-03 3800. Just wondering if it is holding up as good as the Dorman and Delphi units. It has a lifetime warranty too, that kinda gives me the feel goods.

Is this for the 99GT? Has the intake failed, or are you just planning ahead? I'm not sure I've seen a 99 fail, and it'* widely rumored that the 99 has been 'fixed' by GM.

Yeah, this is for my wifes ride. Hers is a 99 GT, not sure of the month it was built. Im just starting to research the goods and bads of ownership. Had the 4T60 rebuilt under the used car warranty by the GM dealer because of a bad input shaft bearing. Now I am worried anbout the intake taking a shiz. Mostly because she drives the car and might not see the tell tails until its too late in the game and a new engine is needed. So I am thinking of getting the parts and having them ready to go at a moments notice.

i'd say go ahead and read the post i just bumped back up to the top about upper intake failure info. its a good read and will get you the basic info about what'* actually going on in your motor.

aside from that, as i mentioned in your q about removing the beaut cover, i'd be more worried about my lower intake gaskets than the upper, but that'* just me...

Yes, the Motormite is the same (same company actually) as the Dorman unit. You are good to go....

YES!! The lowers are the place you should be focusing.

Alos, like Will said...there are no confirmed cases of the 99 upper intakes melting, however, the 99s are not exempt from the poor quality lower gaskets.

-be careful about assuming the '99'* are not failing (-unless the GP is different than the Bonneville) My 99 Bonneville failed catastrophically at 89,000 miles.

And all the responses are correct: The lower gaskets (between clylinder heads and intake manifold) are VERY IMPORTANT to replace.
