Description
Product Overview
The iFJF Engine Valve Cover is a direct OEM-spec replacement for the 2.5L L4 QR25DE engine in 2002-2006 Nissan Altima and Sentra SE-R. This is the early-generation QR25DE cover (13264-3Z001 / 264-982), distinct from the 2007+ version. Manufactured from reinforced polymer with a pre-installed rubber gasket for leak-free sealing at a fraction of dealer cost.
