LS coil packs suggestion for L33

My 2005 GMC Sierra is getting a little sluggish. It has the 5.3 aluminum L33.

I am thinking about replacing the coil packs, plug wires, and spark plugs.

Any suggestions on brands? Or other parts tp change for maintenance?

It has a K&N filter in the stock housing, and I change the oil regularly with Mobil1.

BTW it only has 65K on the truck...

Thanks, Joe
