aFe Direct Fit Cold Air Intake System with Pro 5R Oil-Based Filter - Stage 2 Si - GMC Yukon, 2004

This system boosts engine performance. The sealed air box has special openings that pull in external cold air, and it is quieter than open systems. The oil-based, washable filter works great on paved roads. It includes a plastic intake tube.

Features:

Stage 2 Si sealed design enhances airflow, increasing horsepower and torque
- Provides higher performance gains than aFe Stage 1 intake systems while maintaining a factory appearance
- Includes cross-linked, polypropylene, rotomolded plastic air box that replaces the stock air box
  - Brushed aluminum cover provides easy access to the filter for servicing
  - Specially engineered openings in the air box and a built-in air scoop supply cold air to the engine compartment
- Produces the least amount of noise of any aFe intake system
- Includes molded plastic intake tube that replaces the stock intake tube
  - Without pleats or breaks in the tube, turbulence decreases, boosting horsepower and torque
  - MAF (mass flow sensor) pad located on the intake tube is precision tuned to prevent false "Check Engine" light warnings
Pro 5R oil-based air filter provides maximum airflow and necessary protection for everyday gas and diesel GMC Yukons
- Great for paved-road driving conditions
- 98.6% Filtration efficiency rate made possible by 5 synthetic layers
- Washable and reusable
  - Maintenance recommended every 25,000 to 30,000 miles
Stainless steel installation hardware provided
Satisfies emissions control standards in Canada and all states except California

A. Made from cross-linked, polypropylene, rotomolded plastic, the air box is durable and easy to install; it simply replaces the entire stock air box.

B. Specially engineered openings in the air box and a built-in air scoop located underneath the air filter supply cold air to increase engine efficiency.

C. The cover is made from brushed aluminum, and it unscrews from the air box for easy access to service the filter.

D. The three-angle adapter ring, located on the inside of the heat shield, bridges the connection between the air filter and the intake tube. Its conical shape helps to increase airflow velocity before air enters the intake tube.

E. The heat-insulating, molded plastic intake tube replaces the stock intake tube by screwing into the back of the heat shield, and its improved design decreases back pressure. OEM intake tubes contain pleats and breaks, which increase turbulence. Because aFe intake tubes are seamless and made from one piece, air flows through without generating any turbulence, thereby boosting horsepower and torque. This intake tube also includes a precision tuned MAF (mass flow sensor) pad to prevent false "Check Engine" light warnings. All aFe intake tubes have raised stops that help to form strong connections and prevent slippage.

F. This intake system contains an aFe Pro 5R oil-based air filter for maximum airflow and necessary engine protection. Designed for everyday gas and diesel GMC Yukons, it performs well in paved-road driving conditions. Composed of 100-percent polyurethane, it withstands high engine temperatures. Five layers of progressively finer, medical-grade cotton gauze block 98.6 percent of dirt and grime from clogging your engine. These materials yield the highest performance airflow and extended service interval. All aFe air filters are washable and reusable; cleaning and re-oiling are recommended once every 25,000 to 30,000 miles.
