A-Premium Fuel Injectors Set of 2 for 5.7L V8 Chevrolet/GMC/Cadillac — OE-fit, Six‑Hole Spray

A-Premium Set of 2 fuel injectors restores precise fuel delivery for 5.7L V8 Chevrolet, GMC and Cadillac engines, offering OE-style fit and six-hole spray performance.

These A-Premium injectors are engineered as direct-replacement components for a wide range of late‑1980s to mid‑1990s GM vehicles with the 5.7L V8. Built with a metal plus composite plastic body, factory-style electrical terminals and preinstalled O-rings, the pair is intended to match original spray pattern and flow characteristics so mechanics and DIYers can replace worn or leaking injectors without modifying wiring or fuel rails.

Which vehicles will these injectors fit?

These injectors are specified for numerous Chevrolet, GMC, Cadillac, Buick and related chassis from the late 1980s through the mid‑1990s that use the 5.7L V8. Fitment covers light trucks, SUVs, vans and several full‑size sedans and commercial chassis models.

• Chevrolet: Blazer, C/K series (C1500/C2500/C3500), Suburban, Tahoe, Caprice, G-series vans, P/R series
• GMC: C/K series trucks, Sierra equivalents, Yukon, G-series vans, Jimmy
• Cadillac/Olds/Buick: Brougham, Fleetwood, Caprice variants, Commercial Chassis where noted
• Selected Isuzu NPR and other commercial applications listed for 5.7L V8 compatibility

How do these injectors match original equipment performance?

A-Premium designs these injectors with characteristics meant to replicate the OEM spray pattern and flow rate, including a six‑hole nozzle for atomization. The electrical pin terminals and preinstalled O-rings simplify installation while the mixed metal/composite construction balances durability with corrosion resistance.

• Six-hole nozzle for finer fuel atomization and consistent spray pattern
• Male pin terminals for plug‑and‑play electrical connection
• Preinstalled O-rings to reduce leak risk and speed installation
• Reference numbers included to confirm cross‑reference compatibility (e.g., 17111864)

What should I check before installing these injectors?

Before swapping injectors, inspect fuel rails, electrical connectors and intake sealing surfaces. Cleanliness and correct sealing are key: debris, hardened O-rings or damaged retainers can cause leaks or misfires even with new injectors.

• Verify part reference numbers against the vehicle’s service manual
• Inspect and clean injector bores and fuel rail ports
• Replace or lubricate O-rings if they appear damaged despite being preinstalled
• Confirm electrical continuity and proper connector fit before final assembly

Can these injectors be used for repairs on fleet or commercial vehicles?

Yes — the set is listed for many commercial chassis and fleet models from the era, making it suitable for repair shops servicing older work trucks and vans. The durable materials and OE-style connections help minimize downtime during field repairs.

• Compatible with a variety of commercial chassis and fleet vehicles
• Designed for quick replacement to reduce service time
• Suitable for routine maintenance or targeted injector replacement

Who is this for: This A-Premium two‑injector set is intended for professional technicians, restoration enthusiasts, and DIY owners working on GM 5.7L V8 vehicles from roughly 1987–1995 who need direct-fit replacements that mirror original spray geometry and electrical fitment. It’s ideal when replacing leaking or clogged injectors in matched pairs to maintain balanced fuel delivery across the engine.
