The car already has a cold air intake that, with a WIX ir filter, flows more air than the engine can handle at WOT redline shift points. WIX, Fram, AC Delco, Purolator, PartsMaster - all perfectly good air filters.

I happen to like WIX oil filters and Fram fuel filters.

"OEM" is a relative term - "AC Delco" sources parts and maintenance items from hundreds of different suppliers all over the world. A particular run of "AC Delco" air filter might be made by Purolator, WIX, Fram, others. Oil filters are usually sourced from Champion Labs.

Replace the water pump belt tensioner pulley - yesterday. When (not "if") it seizes it takes the main drive pulley and belt along with it and causes very expensive noises. Half hour job with a couple of wrenches/sockets.

Gates, DAYCO, SKF, Fafnir, AC Delco - $24 at any parts store. The number in the pulley picture is a Gates number.
