Ensure a Dependable Seal with Merchant Automotive

Keeping your Duramax running strong starts with the little things, and the Merchant 10016 Intake Tube Seal Kit is one of those critical details you don't want to overlook. Designed specifically for the 2004.5–2005 GM 2500HD/3500HD models equipped with the 6.6L LLY engine, this kit provides a high-quality solution for resealing the intake tube at the Y-bridge. Over time, the factory seals can become brittle or start to leak, causing a drop in boost pressure, reduced efficiency, and even rough running conditions. If you're chasing down boost leaks or just want to stay ahead of potential issues, these seals are a smart, preventative upgrade.

Sold as a Pair

Each kit includes a pair of durable replacement O-rings, perfectly matched for a factory fit without the guesswork. With two seals per kit, you'll have everything you need to properly service one vehicle. The material is built to withstand the high temperatures and pressures found in your turbocharged intake system, so you can count on lasting performance whether you’re hauling heavy loads, towing, or simply daily driving. Installation is straightforward, making this an ideal project for the weekend DIYer or a quick addition during other intake or turbo maintenance.

Fits: 2004.5, 2005 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LLY
