Overview

The Wehrli Stage 2 High Flow Intake Bundle Kit for 2020-2026 GM Silverado/Sierra 2500HD/3500HD with the 6.6L Duramax L5P engine is designed to optimize airflow for improved turbo performance, throttle response, horsepower, torque, and cooler intake temperatures. This comprehensive kit replaces restrictive OEM components with a high-flow fabricated aluminum intake pipe (4-inch diameter), an oversized 3.5-inch intake horn, and an airbox enclosure featuring a dry filter assembly. It also upgrades the intercooler piping, replacing the factory 2-piece hot and cold side pipes with heavy-duty, 1-piece aluminum pipes (3-inch hot side, 3.5-inch cold side).

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
