I took my car to a auto shop to have them do a Coolant Flush. I was told by the mechanic that he was not able to complete this repair at this time. He showed me where the coolant was leaking around the engine manifold. I was given an estimate of $900 just to have the repair completed which included the coolant flush kit, anti-freeze, oil filter, engine oil cap, thermostat, intake manifold(Fuel Injected) gasket, & intake manifold set.

A close friend who is a great mechanic is going to complete these repairs for me instead, so I am searching for parts. Would you be able to tell me what does it mean when it says Intake Manifold-Fuel Injected and would I have to get the set also? I just want to make sure I get the correct parts for this repair so if you could let me know what all I would need, I will greatly appreciate it. Thanks
