MOOSUN 4 Inch Cold Air Intake Black Tube + Heat Shield
This kit targets Silverado and GMC Sierra models with 4.8L, 5.3L, or 6.0L V8 engines from 1999–2006. It includes a durable intake tube and a steel heat shield with a carbon-black powder coating for longevity and a clean look. Best for owners who want a straightforward upgrade with improved intake routing and practical heat protection. Limitation: installation requires matching vehicle year and engine to ensure compatibility.
RiAiCiING 4” LS Swap Cold Air Intake Kit
Universal LS swap kit designed to fit LS1, LS2, LS3, LQ4, LQ9 along with 4.8L–6.0L engines. Driver or passenger side filter placement helps clearance between radiator and pulleys. It can support Speed Density and Round MAF sensors with additional hardware. Best for restomods and swaps where airflow needs a larger, versatile intake path. Caution: MAF sensor needs extra clamps not included in some setups.
MOOSUN 4 inch Cold Air Intake Black Tube + Heat Shield (Black)
This variant uses a multilayer finish and a carbon black-coated intake pipe with a shield to isolate the filter from engine heat. It is designed for Silverado 1500/1500 HD and 2500/3500 ranges, including the SS variants. Best for buyers who want a rugged, corrosion-resistant setup that emphasizes a wide air inlet. Limitation: vehicle year and model must be checked for exact fit.
102mm Intake Manifold With Fuel Rails And Throttle Body TPS IAC (Endxedo)
Specifically crafted for GM LS engines, this 102mm manifold accommodates LS1/LS2/LS6 cathedral ports and offers compatibility with several high-performance configurations. Best for builds that require a direct 102mm intake path with integrated fuel rails and throttle body. Limitation: installation assumes matching LS-series components and may require additional adapters depending on the project.
MooSun 4″ Performance Cold Air Intake Kit
Designed for a wide range of GM trucks and SUVs, this kit features a durable finish and a large-diameter intake path to draw colder air. It supports Silverado/Sierra families and is suitable for 4.8L/5.3L/6.0L engines. Best for owners seeking a robust, visually coordinated upgrade with emphasis on airflow and heat isolation. Caution: confirm exact vehicle fitment before purchase due to broad compatibility notes.
Hoypeyfiy Air Intake Hose Throttle Body Tube
Targeted for Toyota 4Runner and Pickup 2.4L 22RE, this hose is a reliable replacement option for cracked or leaky air intake hoses. It is built from durable rubber with high-strength fibers to stabilize airflow and sealing performance. Best for owners focused on restoring proper intake seal rather than broad engine performance gains. Limitation: not compatible with LS-based 102mm setups.
TEMSONE 102MM Intake Manifold Fabricated EFI
Fabricated from 6061 aluminum with MAP port provision, this manifold supports 102mm throttle body integration for LS-based engines. It targets a precise fitment with cathedral-port LS heads and is compatible with multiple high-performance applications. Best for dedicated LS builds requiring a robust, light manifold with integrated MAP access. Limitation: assembly may require additional fuel rails and sensors depending on the project.
ICT Billet LS 92mm TB to 102mm Manifold Adapter
This adapter converts a 92mm 4-bolt throttle body to a 102mm 4-bolt intake manifold. Made in the USA from aerospace-grade billet aluminum, it includes bolts and O-ring seal. Best for projects upgrading to a 102mm manifold while preserving a 92mm throttle body. Limitation: requires a compatible 102mm manifold and proper fitment checks for bolt pattern alignment.
Buying Guide
What should you consider when pairing a 102mm throttle body with a cold air intake?
- Fitment and engine family: Focus on LS-based engines or GM V8s that commonly use 102mm or larger throttle bodies.
- Airflow path: Look for larger-diameter tubes, heat shields, and flared intakes to minimize intake resistance and heat soak.
- Heat management: Heat shields and shields around the filter help maintain colder air intake for better combustion efficiency.
- Sensor compatibility: Ensure MAF/Speed Density compatibility or that the kit includes necessary adapters for the specific sensor setup.
- Installation requirements: Some kits need additional clamps, couplers, or fuel rails; confirm what’s included and what to purchase separately.
- Durability and materials: Powder coatings, multilayer finishes, and corrosion-resistant components contribute to long-term performance in harsh environments.
Frequently Asked Questions
- Q: Is a 102mm throttle body compatible with all LS engines? A: Compatibility depends on the manifold, sensor arrangement, and year/model. Check the specific product’s fitment notes.
- Q: Will upgrading to 102mm require additional fuel rails or sensors? A: Some manifolds and kits include rails and MAP/TPS provisions; others may require adapters or extra parts.
- Q: Do cold air intakes always improve horsepower? A: Gains depend on the entire intake-path design and engine setup. Expect modest improvements with properly matched components.
- Q: Are heat shields essential? A: Heat shields help keep the intake air cooler, which can improve performance under load.
- Q: Can I install these myself, or do I need a shop? A: Many kits are designed for DIY installation, but some configurations may benefit from professional installation for precise fuel and sensor calibration.
- Q: Which option is best for a restomod LS build? A: Look for universal LS swap kits or 102mm manifold options with MAP ports and robust build quality.
