Product Features

Stage 1 Cold Air Intake System Type Cx w/ Pro-Dry S

GM Duramax 6.6L LB7 (2001-2004)


Why Stage 1?

With the Stage 1 intake system, we replace the stock air box and the stock air filter.  By replacing the restrictive air box and air filter, there is a noticeable improvement in airflow and power.  However, Stage 1 retains the stock intake tract.

Element: Open element: Air filter element is exposed or partially covered
Horsepower: More horsepower using cold outside air and better airflow
Torque: Noticeable low end torque gains

Cost: Our best bargain for value-conscious buyers
Sound: Noticeable sound: Great engine noise improvement
Style: One-piece steel heat shield/air box, uses stock intake tract
Installation: 30-60 minutes: Requires removal of the stock air box

Features:
  •     One-piece, 16-gauge powder-coated heat shield
  •     Uses stock intake tube
  •     Huge high-flow, high-performance conical air filters in three types
  •     Powder-coated steel or brushed aluminum cover
Benefits:
  •     15 HP gain
  •     34 LB-FT Torque gain
  •     Easy installation and performance at a value price
  •     Blocks heat and directs cold air to the filter
   
THE aFe ADVANTAGE

ONE-PIECE HEAT SHIELD:
Welded, one-piece heat shields that use no additional brackets for the easiest installation possible.

RUBBER TRIM SEAL:
aFe uses top-quality flexible rubber trim seal between the heat shield and vehicle hood to block hot air from the filter.

3-ANGLE ADAPTER:
aFe intakes uses 3-angle adapters or velocity stacks to minimize aerodynamic loss. (Select applications)

QUALITY HARDWARE:
aFe uses only top-quality hardware like stainless steel button head bolts and brass inserts.
