Cold Air Intake Kit - Chevy Silverado & C/K Series (1988-1995) 5.7L V8
Breathe New Life into Your OBS Legend.
The "Old Body Style" (OBS) Chevy C/K Silverado trucks from 1988 to 1995 are icons of American durability. Whether you are driving a C1500 daily or hauling with a K2500, your truck was built to work. However, the factory air intake system—often restrictive and designed for noise suppression—is choking your engine's potential.
This High-Performance Cold Air Intake Kit is the ultimate wake-up call for your 5.7L V8 engine. By replacing the restrictive stock piping with mandrel-bent aluminum, this system smoothes out the airflow path, forcing a higher volume of cold, oxygen-rich air into your engine. The result? A truck that pulls harder and sounds meaner.
Why Your Truck Needs This Upgrade
You rely on your truck for power and performance. Standard paper filters and baffled intake tubes create turbulence that slows down air velocity. Our system eliminates these bottlenecks, delivering immediate improvements you can feel in the pedal.
Imagine merging onto the highway or towing a heavy load. Instead of the engine struggling for breath, you get a surge of torque and a deep, aggressive induction growl that reminds you why you drive a V8.
Performance Benefits & Features
- Proven Power Gains: Dyno-proven to increase horsepower by 5–7% and torque by 6–8%. Get the extra muscle you need for towing and passing.
- Instant Throttle Response: By reducing restriction, your engine responds faster to pedal input. Say goodbye to that sluggish feeling off the line.
- Superior Filtration: Includes a high-flow, washable, and reusable cone filter with 95% filtration efficiency. Stop buying throw-away paper filters.
- Engine Bay Aesthetics: The polished aluminum piping adds a clean, custom, show-quality look under the hood.
- Built to Last: Anodized finish resists rust, heat, and corrosion, ensuring your intake survives the lifespan of your truck.
- Fuel Efficiency: Optimized airflow improves combustion efficiency, which can help improve gas mileage during normal driving conditions.

DIY Guide: Cold Air Intake for Chevy Silverado (1988-1995) 5.7L V8 Engine for 1988-1995 Chevrolet Silverado C/K Trucks 5.7L
Required Tools
- 10mm & 13mm Sockets with Ratchet and Extension
- 8mm (or 5/16") Nut Driver or Flathead Screwdriver (for hose clamps)
- Slip-Joint Pliers (for factory breather hose clip)
- 7/16" Wrench (for TBI center stud wingnut/nut)
Do not over-tighten the center mounting nut on the Throttle Body Injection (TBI) plenum hat. Snugging it down with excessive force can warp the cast aluminum housing or strip the factory throttle body threads. Ensure the base gasket is seated evenly before tightening.
Phase 1: Factory Component Removal
- Disconnect the negative battery cable using a 10mm socket or wrench to reset the ECU fuel trims.
- Unscrew the wingnut on top of the factory metal air cleaner housing and lift the lid, paper filter, and intake ducting upward slightly.
- Detach the metal crankcase breather tube from the side of the stock air cleaner base and unplug the Intake Air Temperature (IAT) sensor harness if mounted in the lower housing.
- Remove the entire factory air cleaner assembly, flex tube, and passenger-side fender resonator box by removing the 10mm mounting bolts.
Phase 2: Aftermarket Installation
- Place the base gasket onto the throttle body neck, then seat the silver cast aluminum TBI plenum hat over the center stud and thread the retaining bolt/nut loosely by hand.
- Slide the black silicone coupler with two stainless worm-gear clamps onto the plenum hat, insert the polished aluminum intake pipe, and connect the factory breather line to the side port on the plenum hat.
- Align the welded mounting tab on the polished intake tube with a factory accessory bracket hole, secure it loosely, and clamp the open-element black cone filter onto the end of the tube using an 8mm nut driver.
- Verify hood clearance, tighten the TBI center bolt, mounting bracket bolt, and all three hose clamps, then reconnect the negative battery terminal.
