Buy Acura Integra Fuel Injectors

Fuel injectors-sometimes called fuel nozzles, spray valves, or injector tips-push a fine mist of gasoline into each Acura Integra cylinder so the air-fuel mix burns clean and strong. The 2024 Integra's 1.5-liter turbo engine, for example, runs high-pressure direct injectors that spray fuel at up to 20 MPa, boosting power while trimming emissions, as noted in the Acura Integra fact sheet. (Acura) When an injector sticks, leaks, or clogs, the engine may surge, misfire, or smell like raw fuel-issues documented by Integra owners on enthusiast forums. (IntegraForums) Good injectors save fuel, cut smog, and keep the sporty Integra fun to drive.

A fuel injector is an electronically controlled valve that opens for just milliseconds, letting a measured shot of gasoline atomize into the intake port or directly into the combustion chamber, depending on the engine design. (Wikipedia) Compared with old-style carburetors, injectors deliver more exact amounts of fuel, improving throttle response and fuel economy. (Rislone) Modern gasoline direct injection (GDI) systems, like those in recent Integra and TLX models, place the nozzle right in the cylinder for even finer control and higher compression ratios.

• 1986-2001 Integra (B-series engines). The B18B1/B18C1/B18C5 motors use saturated, multi-port injectors flowing about 240-250 cc/min at 43 psi. (HA Motorsports)
• 2023-present Integra (DE4 chassis). The L15CA 1.5-liter turbo employs high-pressure GDI injectors designed for up to 20 MPa rail pressure. (Acura)
  Honda service guidance notes that injector part numbers differ by trim and emission spec, so always match the engine code before ordering. (NHTSA)

• Rough idle or cylinder misfire codes (P0300 series).
• Long crank or hard start after the car sits, caused by leaking injector tips that flood a cylinder. (Cars.com)
• Strong fuel smell and poorer mileage than usual-often the first clue of a dripping spray valve.
• Rattling sound under the hood as the ECU increases injector pulse to compensate for clogging. (IntegraForums)

Light deposits can be cleared with a bottle of quality fuel-system cleaner every 5,000 miles, according to AAA's maintenance guide. For heavy clogging, professional ultrasonic cleaning or replacement is the sure cure. (Cars.com) When swapping injectors, always use new O-rings and relieve rail pressure first to avoid spills.

• Stick with Top-Tier gasoline to keep varnish at bay, says Cars.com.
• Drive the car long enough for the engine to reach full temperature; short trips encourage deposits. (US EPA)
• Replace the fuel filter on schedule so the tiny injector screens stay clear. (AAA)

Track enthusiasts sometimes step up to 310 cc/min injectors to feed turbo or high-lift cam builds; flow charts show stock ECU maps can handle up to about 260 hp before duty cycle maxes out. (HA Motorsports, D-Series) Beyond that, a programmable ECU and larger pump are required to keep pulse width below 85 %.

Because injectors meter fuel so precisely, they lower carbon monoxide and unburned hydrocarbon emissions, a key reason the EPA pushed the industry toward electronic injection. (US EPA) Tests also show that reduced fuel volatility-possible with efficient injectors-cuts evaporative smog. (EPA NEEP)

1. Depressurize the rail via the service Schrader valve or the fuel-pump fuse.
2. Disconnect the negative battery cable.
3. Unclip wiring harness plugs and unbolt the fuel rail.
4. Lift the rail off; the injectors will come out together. (YouTube)
5. Swap O-rings, lube with clean engine oil, and press new injectors into the rail.
6. Reinstall everything and prime the pump twice before starting.

Keep your Acura Integra's fuel injectors clean, matched to your engine's needs, and promptly replaced when faulty. Doing so saves gas, protects the planet, and lets the nimble hatch-or the new turbo sedan-deliver the eager performance Acura fans love.
