Cold Air Intake 4 in Silver Tube with Heat Shield - 5-10% Power Gain

In this review of the MOOSUN 4 in Cold Air Intake with silver tube and heat shield, the bottom line is simple: it is a budget-friendly choice for owners of late 1990s to mid 2000s GM V8 trucks who want a straightforward power and sound upgrade. The reviewer found the kit increases throttle response and creates a pleasing intake note while keeping installation simple, so it is best for DIYers and LS swap projects where a direct-fit, largely bolt-on solution is preferred.

Key Features

• Fitment: Covers a wide range of Chevrolet and GMC V8 trucks and SUVs from 1999 to 2007, which reduces the need to search for model-specific parts.
• Power and torque gains: Designed to increase around 5-10% horsepower and 6-10% torque, delivering noticeable improvement in midrange response.
• Sound character: Produces an attractive intake noise that some owners describe as deeper and less buzzy than many open-intake kits.
• Complete kit: Ships with the tube and heat shield so no additional parts are required for installation on matched vehicles, simplifying the upgrade.
• Easy install: Intended for straightforward installation with common hand tools, making it accessible for home mechanics and LS swap builders.

Who It's For

This intake is aimed at owners of Silverado, Sierra, Yukon, Avalanche, Suburban and Tahoe models within the listed model years who want a clean, visible intake upgrade that improves engine breathing and sound without complex modification. It also suits enthusiasts performing LS swaps who are looking for a reasonably priced intake that fits many GM V8 platforms.

It may not be the best choice for drivers seeking maximum horsepower from a high-end forced-induction or track-focused build, or for those who require an intake with vehicle-specific dyno validation for every model year; fitment can be mixed on some years and trimming or adjustment may be necessary in rare cases.

Pros & Cons

Cons
