This fully enclosed air intake system is designed to keep hot air out of the intake air stream. This intake seals tightly against cold air sources from within the engine bay, which ensures an improvement in performance and efficiency. Through real world and user testing, Bully Dog has proven that an enclosed air intake system along with a high flow cotton gauze filter will yield better air flow and colder intake temperatures than a stock system and an aftermarket open intake design.
Proven Results:
- 10% greater air flow at 60 mph in cruise control
- 10 degree lower intake temperatures at 60 mph in cruise control
- 10-15 added rear wheel horsepower
- 10-30 added rear wheel lbs. ft. of torque
Additional Features:
- Easy installation - 30 minutes or less
- ISO 5011 certified air filter
- Easy to remove lid for air filter maintenance
- Lifetime cleanable and reusable air filter
