A Plus Auto 4.3L V6 Fuel Injector Kit — 6-Cylinder Direct-Fit Set with Preinstalled O‑Rings and Basket Filters

A Plus Auto Spider fuel injector set for 6-cylinder 4.3L engines replaces OEM units to restore consistent spray pattern, reliable flow and durable sealing for Chevy, GMC, Isuzu and Oldsmobile applications.

This complete six-injector kit is engineered as a direct-fit replacement for many 4.3L V6 Chevrolet and GMC engines from the mid-1990s through the 2010s. Each injector is factory-tested for leakage, spray atomization, and nozzle uniformity across operating speeds, with pre-installed O-rings and a built-in inlet basket filter to reduce contaminants. The assembly is sold with a one-year, unlimited-mile warranty and matches several common aftermarket and OEM part numbers for easy cross-referencing.

Which vehicles will these injectors fit?

These injectors are compatible with a broad range of GM and related platforms using the 4.3L V6. Fitment covers late‑1990s to early‑2010s models across Chevrolet, GMC, Isuzu and Oldsmobile where this injection spec was used. Always cross‑check the engine size and part numbers before ordering.

• Chevrolet: Astro, Blazer, C1500, Express, K1500, P30, S10, Silverado (selected years)
• GMC: C1500, Jimmy, K1500, P3500, Safari, Savana, Sierra, Sonoma (selected years)
• Isuzu & Oldsmobile: Hombre and Bravada 4.3L V6 model years listed in product details
• Replaces common OE/aftermarket numbers such as 12568332, 17113673, 19210688 and several FJ/BWD references

How do these injectors perform compared with OEM units?

Each injector in the set is dynamically tested for flow rate, spray angle, and leak tightness to ensure consistent fuel delivery similar to the original equipment. The coil resistance and low leakage spec maintain predictable electrical and hydraulic behavior, helping the engine run smoothly when installed correctly.

• Dynamic flow: approximately 55–63 ml/min for balanced fueling
• Coil resistance: 12.5 ± 1 Ω for stable electrical response
• Leakage: ≤0.8 kPa over 25 seconds, minimizing drips and flooding
• Pre-installed O-rings and basket filter help prevent leaks and debris entry

What should I expect during installation and maintenance?

Installation is straightforward for anyone familiar with fuel rail removal on these V6 engines, since the injectors are blade‑terminal, direct-fit replacements. Replace or lubricate O-rings during installation and inspect the inlet basket filter for trapped debris. If your engine has long-term deposits, consider a professional cleaning of intake and rails to optimize spray.

• Terminal type: 2-blade electrical connector; use compatible harness plugs
• O-rings: pre-installed—lubricate before insertion to avoid tearing
• Filter basket: built-in inlet screen to trap particulates
• Recommended: check fuel rail pressure and injector pulse after fitment

What warranty and part cross-reference information is included?

The kit includes a one-year, unlimited-mile warranty supported by A Plus Auto, providing replacement coverage for defects in manufacturing. Multiple aftermarket and OEM part numbers are referenced to help you confirm compatibility with your vehicle before purchase.

• 1-Year unlimited-mile warranty for peace of mind
• Cross-references include common numbers like 12568332, 17113673 and several FJ/BWD codes
• Each injector was subject to simulated tests for atomization, leakage and nozzle uniformity

Who is this for: Technicians and DIYers who need a reliable, cost-effective set of six fuel injectors for 4.3L V6 Chevrolet, GMC, Isuzu or Oldsmobile engines. Ideal when replacing a bank of injectors together to ensure balanced fuel delivery, this kit suits owners restoring older GM vans, trucks and SUVs or replacing worn or leaking injectors without resorting to dealer-pricing.
