Nissan Fuel Injector 16600-5CA0A/1VA0A/BV80A/6KA0A Direct Replacement, Precise Fuel Delivery

Nissan engine fuel injectors (OEM: 16600-5CA0A, 1VA0A, BV80A, 6KA0A and 15710-68M00) installed on the intake manifold; atomize fuel precisely and directly affect power and fuel economy. Fits many Nissan models post-2000; installation difficulty moderate; 1.5–2 hours; pay attention to high-pressure fuel line seals. If idle unstable, acceleration hesitation, rising fuel consumption, or MIL lights, injectors may be clogged or poorly atomizing; replacement restores fuel delivery.
