FJ504 Spider Fuel Injector Kit For Chevy GMC 5.0L 5.7L V8 (1996-2002) - High Flow MPFI Conversion For C1500, Suburban, Tahoe, Escalade

About This Product

If you're driving a Chevy or GMC with the 5.0L or 5.7L V8 from 1996-2002, you know the factory spider injectors can be trouble. This FJ504 replacement kit is a solid upgrade that actually improves performance while solving common fuel delivery issues. The high-flow design delivers about 15% more fuel than stock, which means better throttle response and reduced engine knock. The 304 stainless steel nozzles and nickel-plated terminals resist corrosion from modern fuel additives, and the quadruple O-ring seals prevent leaks that plague the original design. Installation is surprisingly straightforward - it's basically plug-and-play with color-coded connectors and all the hardware included. You can typically knock this out in under an hour with basic tools, no ECU reprogramming needed. It's compatible with C1500/C2500/C3500 trucks, Suburbans, Tahoes, Escalades, Savana and Express vans from those model years. The improved fuel atomization (down to 2.5μm) means better combustion efficiency, which can actually improve your gas mileage. These are lab-tested to maintain 98% flow consistency even after 50,000 miles, and they meet EPA Tier 1 standards so you'll pass smog checks. If you're dealing with rough idle, poor acceleration, or just want to prevent future problems, this upgrade makes a lot of sense. Much more reliable than the original equipment and way cheaper than dealership parts!
