Under the Magnuson-Moss Act, a vehicle manufacturer or dealer cannot discriminate against after-market filters that meet or exceed OEM standards. All System 1 filters exceed standards. Proper use of our filters will not void your warranty.
Here noted 30 micron, primarily recommended for 0- to 50-weight oil.

But then many often do not put too much faith in manufacturer specs.
