This is a stock M90 snout that has been rebuilt to OEM specs. We take used cores, completely disassemble/clean/sandblast them, powder-coat, and reassemble with new bearings and a seal. 

How to order your rebuilt snout:

Model: This determines what generation supercharger you need the snout for. Gen3 is what comes on the '97-03 Grand Prix GTP, 97+ Regal, '04+ Impala/Monte SS, '97+ Bonneville SSEi, '96+ Park Ave Ultra/Riviera. The Gen5 only comes on the '04-07 supercharged Grand Prix models.

Core Charge: This is a refundable core charge. This allows us to ship you a core first so you can swap it with the one on your car and then return your used one for the core charge amount. We offer an extra 10% back if you want it as an in store credit instead of refunding it the way it was paid.

Pulley or hub installed: If you would like a press on pulley or modular pulley system installed on the snout we will do so free of charge. Just add the corresponding item to your cart and make sure to notate that you want the pulley/hub installed upon checkout. If you would like to retain your stock pulley and want us to swap it over, you must leave us a note stating this so we can include the pulley on the rebuilt snout. Due to the disassembly process we can not guarantee your stock pulley will not show slight damage/install markings.

These are the rest of the items you would need to complete this snout swap:

NoteA bad snout seal will cause supercharger oil to leak out from the end of the housing and then gets on the pulley, it then flings it all over your engine bay. 

Bad snout bearings make a buzzing noise that increases with engine RPM and will get louder and louder until the SC comes apart.

A worn coupler will cause a rattling noise only at idle that will go away if you rev it. 

A bad rotor pack also makes a rattling noise like in this video. Click here to hear Rotor Rattle

Core note: If you select "sending in core first" and your snout core is deemed defective, you will be charged a core charge of $50 before we release/ship your order. If you order refundable core and it is deemed as unrepairable/unusable you will be informed and no refund will be given.
