Question about coils and intake I bought an '04 aluminum 5.3 that is complete except for intake and coils. I thought this would be easy to fix, but there are a lot of coil options. Is there a way to know which coils my engine needs?
Also, for a street motor, is there any reason to run anything other than a Doorman intake?
EDIT - fixed year.

No such thing as an '02 aluminum 5.3. '03-'05 LM4, or '05-'07 L33 are the only Gen III aluminum 5.3's. Either yours is newer than you thought or it's not an aluminum block.
Get a set of truck coils from the junkyard. They are the best coils and are what came on 5.3's.
What is it going into? Hood clearance will determine your choice of intake manifolds.
