This fuel injector fits 3.8L engines found in 07-11 Jeep Wrangler models. Fuel injectors are responsible for getting gasoline into the engine in a precise and carefully engineered pattern. If your engine no longer runs smoothly, is experiencing sputtering, or has suffered a loss of performance, these might be signs that suggest a clogged fuel injector from particles that have accumulated over time. Omix-ADA has you covered with our new replacement fuel injectors that help restore engine efficiency.
