Show original supplier description
The Genuine Infiniti 16119-AR200 is a throttle chamber assembly, also referred to as a throttle body, designed as a direct replacement part. It is meticulously produced to official factory specifications and undergoes stringent quality checks to ensure long-lasting performance and a precise fit. This specific unit is a refurbished Throttle Body Injection (TBI) system for Infiniti M45 and Q45 vehicles. It is compatible with 2003-2004 Infiniti M45 (S, SP trims with 8 Cyl 4.5L VK45DE engine) and 2002-2004 Infiniti Q45 (8 Cyl 4.5L VK45DE engine). The part's dimensions are 10.6 x 6.6 x 5.1 inches and it weighs 5.00 pounds. Installation of this throttle body injection unit may require programming by a dealer to ensure optimal performance. A 1-Year Limited Warranty is included with this part, and a $100 refundable core deposit is part of the purchase price. If you are unsure about the diagnosis, a misdiagnosis fee structure is in place where a $75 restocking fee plus shipping and handling applies for returns after testing the part.
