Installation Notes and Tips

Verify the existing filter dimensions and OE part number before installation. Confirm the air box is clean, then seat the panel filter evenly in the housing so the seal closes uniformly. For BMW 528i, 528i xDrive, X1, Z4, and 520i applications, compare the old filter to the new WIX 49208 before closing the air box to ensure proper fit.
