The MotorWest Performance HP831-6PACK-L1 is a set of six reconditioned fuel injectors, originally an Aisin Part # 23250-62040, designed as a stock replacement for specific Toyota vehicles. These injectors have undergone a rigorous reconditioning process in MotorWest's Southern California facility, ensuring they meet or exceed factory specifications. The company emphasizes offering only OEM/brand name units to guarantee proper fitment, function, and longevity. These fuel injectors are compatible with 1999-2004 Toyota 4Runner, Tundra, and Tacoma models featuring the 3.4L V6 5VZ-FE engine. The original brown Aisin injectors, which this product replaces, have a known internal solenoid defect that can lead to failure over time, often manifesting as intermittent misfires that worsen with engine temperature and eventually result in a complete misfire. While this specific product (HP831-6PACK-L1) has been discontinued, MotorWest Performance now offers a more reliable and cost-effective Denso injector replacement, also available under SKU HP831. Customers are directed to search the store for HP831 or click a provided link for these replacements, which are covered by a lifetime warranty.
