Mr. Wong Yee Yong once pointed out the importance of getting the correct oil filter for the 4AG engine or else it could cause mechanical failure. Some even mystically report that VVT operation improved to smoother engagement after using the correct oil filter. Personally, don't know???
90915-YZZC5 vs. 90915-YZZC6
The C5 box (namely 90915-YZZC5) specifically print for A type engine application but excluding 4AG. Therefore if you care enough what Toyota engineers got to say, don't use the wrong oil filter.
There is another model 90915-10004 which also state suitable for 4AG.
The C5 is priced around Ringgit Malaysia (RM) 18 while the C6 is priced at Ringgit Malaysia (RM) 28 each.
UPDATES
Allot of oil filters above can be fitted to 4AG, but not all are recommended, so don't get the wrong one.

A friend's MR2 SW20, 1st gen car but using 2nd gen engine running on 1st gen ECU (AFM) experience "Engine Warning Light" for around 20 seconds of start-up because the oil filter is not the correct one. This is a rare but serious indication of the need to use the correct oil filters.
90915-YZZB6 Big Oil Filters for Toyota Corolla Levin / Trueno 4A-GE
Presenting Oil Filter model B6: -
The white filter is not 90915-YZZC6 but please see the box on the left which is for C6. Hence this white filter is a quick comparison to the size difference between C6 versus B6.
The B6 unit is taller as well as larger in diameter. I do not know if it is real versus I just want to fool my self with psychology. The big filter feel better for the engine.
VVT operation seems to be like improved ........ like no delay ...............like seemless ..........you've got to try it to know it :)
Saying this allot of people have been very worried about oil pressure drop when using big ass oil cooler or big ass oil filter. Just some figures for you to reference.
My engine oil pressure at idling is around 80 psi in the cold morning and 40 psi in the hot afternoon. Oil return from cooler temperature is 50 celcius.
The engine oil pressure above 3,000 rpm is over 100 psi in the cold morning and around 80 psi in the hot afternoon. Oil return from cooler temperature is around 70 celcius.
Only extremely long traffic jam stops like over 30 minutes of really non movement and very very hot afternoon will see oil temperature max out at 83 celcius. In this case oil pressure still above 40 psi at idling and around 80 psi above 3,000 rpm.
The readings are surprisingly same for many types of engine oil class as well as brand. There is no modification made to the original engine oil pump. This is a completely fair test.
High revving the engine also does not create oil temperature above 75 celcius. Dam good big ass oil cooler. However mineral oil (normal cheap brands) died around 1,000 km travel. 4A-GE 20v cannot use normal mineral oil.
Summary
A lot of oil filters above can be fitted to 4AG, but not all are recommended, so don't get the wrong one.
