im starting to here the coupler noise at idle so i figure change it now any one know where to find the product and and know how long it takes to do its a 1995 bonny

I think those are the same as the M90 couplers, you can get them at intense-racing and ZZ performance. Should be able to do it in about 3 hours, I seem to recall you need to remove the supercharger to do it. So you will need a SC gasket, throttle body gasket, and coolant O rings.

They are the same coupler.

FWIW
M62 and M90 all generations on both ...use the same coupler.

ok thankz alot maybe ill do this next week how much is a gasket kit then for the intake and throttle body

You will need to check at ZZP or intense. I believe the SC gasket is about $10, the TB gasket is about $8 and the Orings are like $5. You will also need some red RTV to seal the snout, there'* no gasket there. You can either use the snout oil, or save some money and use Mobil1 synthetic 5w30

do u just use the gm supercharger oil cuz i still got some here

If you have it on hand, use it. I used up the last of mine and I'm not using Mobil1

does the mobile one do just as good of a job

Should be the same. GM released a notice to dealers saying Mobil1 synt 5w30 can be used in supercharger snouts.

how much do i add
