Cadillac SRX Fuel Injector
17 itemsCadillac SRX Fuel Injector applications distinguish the earlier 3.0L direct-injected V6 from the later 3.6L V6. A-Premium's supported APFI173 product includes an O-ring for its specified earlier application, combining injector replacement with a fresh sealing contact.

Fresh Sealing, Even Combustion Cadillac SRX Fuel Injectors
Replacing an injector in a Cadillac SRX opens a fuel connection as well as removes a failed component. For an owner keeping this luxury crossover, a sound replacement should address both the injector's work and the joint disturbed during repair. A-Premium Cadillac SRX fuel injectors meter gasoline for consistent combustion, with an included O-ring on the supported direct-injection product to renew its sealing contact.
That combination makes a concrete difference to the repair: the new injector supplies measured fuel while its replacement O-ring closes the connection around it. Restoring the failed component and that sealing surface helps bring the SRX back to even-running passenger travel without carrying the old compressed O-ring into the new installation.
Why Choose A-Premium Cadillac SRX Fuel Injectors?
An SRX repair should remain sound after the first smooth start. A rough-running injector affects the crossover's passenger experience, while a sealing joint disturbed during removal needs attention of its own. Treating both as part of the replacement helps avoid reopening the same connection.
The supported A-Premium SRX direct-injection product includes an O-ring and new injector hardware. The O-ring seals the joint around the injector, while the nozzle disperses fuel for combustion. This combines the fuel-dispensing repair with renewal of the sealing part supplied for that product.
Passenger travel also calls for consistent running while the SRX is moving gently through traffic. The injector meters small fuel amounts during light demand, and its nozzle forms the spray that mixes with air, addressing both delivery quantity and mixture preparation. These functions support a composed drive once the fuel joint is secure.
- Included Replacement O-Ring: An O-ring supplied with the supported SRX injector seals its fuel connection. The repair renews that contact instead of reusing the old compressed ring, reducing one reason to reopen the crossover's injector installation.
- Low-Demand Fuel Metering: The injector regulates small gasoline quantities as the engine runs under light demand. In the SRX's passenger-focused use, consistent delivery helps keep uneven combustion from disturbing gentle progress through traffic.
- Nozzle Spray for Air Mixing: The nozzle disperses fuel into droplets available to mix with air. Replacing an irregular spray helps the SRX burn the delivered fuel consistently, supporting smoother engine operation during a passenger trip.
FAQs About Cadillac SRX Fuel Injectors
Did the SRX's move from the 3.0L V6 to the 3.6L V6 change the injector application?
Yes. Cadillac introduced the 3.6L direct-injected V6 for the 2012 SRX, replacing the earlier 3.0L direct-injected V6. Both use direct injection, but that shared description does not establish interchange. The injector must list the engine and model year being serviced.
Does the earlier SRX 3.0L V6 use a port injector?
No. Cadillac identifies that engine as direct-injected. Its injector delivers fuel into the combustion chamber, which changes the pressure and sealing requirements compared with port injection. Choose the direct-injection application for the 3.0L rather than treating every SRX V6 injector as equivalent.
Does the APFI173 SRX injector product include an O-ring?
Yes. Its specifications explicitly list an included O-ring for the stated 2010?2011 SRX application. That settles the supplied O-ring, but it does not establish that every seal or other one-time-use installation part required by the vehicle's service procedure is included.
Will replacing only an O-ring fix an injector that leaks through its nozzle?
No. The O-ring seals an external joint, while fuel leaking from a closed nozzle passes through the injector's internal valve. An injector with damaged internal sealing needs repair or replacement of the unit itself. A fresh external ring does not correct that internal leak.
