AC/Delco
For BEST performance you should exactly what came in it and that is AC Delco.
The Chevy Impala did not come out in 2004. The eighth generation Impala came out in 2000 and then the ninth generation Impala came out in 2006. The tenth generation is expected for 2014.
sure, it should. yes, as long as its the same motor that came out of your car in the first place, it should fit fine. if the motor is different you will also have to grab the Pcm and related wires out of the donor car with the motor.
Any engine that the 03 Impala came with takes 4.5 qts.
Yes, Chevy is still producing the Impala. Their latest model came out in 2011, and is categorized as a sports sedan. Average price is around $24,495.
The 1965 impala came in multiple interior colors: red, black, blue...possible more.
You will not go wrong installing the OEM AC/Delco plugs, just like came in the car. This is what I would install in a GM vehicle.
Not without modification
Dont know what size the 6 cyl. was, but the v8 was the 283 and the 327. I think it also came with a 409
The automatics had the 4L60E.
Most came with a V-8 engine, which took 8 spark plugs.
