When you need it. Black anodized aluminum brackets mount to existing locations on your vehicle. No modifications are required for installation. Our custom molded air box coupler attaches to the air box with 6 stainless steel 10-32 screws. On the inside of the box, it has a large 6 inch mounting flange to accept the huge air filter. The larger opening ensures you won't be starving your motor during acceleration. As the coupler passes through the air box wall, it transitions to 5 inch OD to accept our high gloss black silicone hump hose. The hump hose takes up the movement of the air tube. This design allows us to mount the airbox assembly solidly to maintain a good seal between our intake components while still having the ability to absorb motor rock. Most intakes simply cut an oversize hole for this. The other end of the hump hose accepts our custom molded air inlet tube which has a huge 5 inch OD inlet. The tube transitions down through its length allowing the air to gain velocity as it travels towards the throttle body. At the throttle body, we use a high gloss silicone hose that mounts our tube solidly so good alignment is maintained, even during motor rock. From start to finish, we have designed and built this air intake with all of the qualities to make it work! Please compare our design and components to the competion and you'll see the differences. All oil filters come pre-oiled and ready for use. Thank you for taking the time to learn about our products. This air intake system fits 2005-10 Charger models.
