Installation Notes and Tips

Clean both mating surfaces before installation and inspect the plenum and intake surfaces for damage, warping, or old gasket residue. Confirm upper-position fitment before ordering, since AMS5542 is listed for upper intake applications only. Verify the vehicle year, make, and model against the fitment table, especially on Nissan Maxima, Nissan Altima, and Nissan Murano applications.

Quality Assurance

Apex AMS5542 is cataloged as a direct-fit sealing component for the listed vehicles and upper intake position. Part number AMS5542 should be matched to the vehicle application before installation to confirm correct fitment.
