ProFab Air Horn:
This air horn is black powder coated mild steel and a huge 3 1/2" in diameter.

Testers have reported more turbo sound, faster spool up, and more boost!!

Independent dyno tests have shown an increase of 15 Hp!!

Some minor modification to the wiring loom may be needed to make it fit.

PPE Boost Increase Valve:
Increase your turbo boost pressure from the stock 18-20 to 28-30 PSI in 5 easy minutes. Designed for 2001 - 2004 Duramax LB7 diesel engines, the PPE Boost Increase Valve will not only produce additional horsepower and torque, it will also reduce the those dreaded EGTs. Additional fueling via a PPE Xcelerator programmer may be needed to gain higher boost levels.

S&B Cold Air Intake:
Airflow Rating: Flows 47.8% better than the Stock Intake
Efficiency Rating: 99.81% Efficient @ 653 CFM (ISO Course Dust)
