The new 57-1556 custom designed intake system offers an easy to install replacement to the restrictive factory air box. This performance air intake is capable of delivering an estimated 8.7 horsepower and 9.14 lb-ft of torque at 5006rpm, making your towing job easier than ever.

The 57-1556 air intake system comes complete with a washable and reusable K&N conical air filter, part number RF-1042. This high quality performance air filter is constructed using multiple layers of oiled cotton gauze to allow higher airflow than a standard disposable paper air filter while it protecting your engine from harmful contaminants. The 57-1556 can be used for up to 100,000 miles before the air filter needs to be serviced depending on driving conditions. Like other K&N air intakes this system is backed with K&N's Million Mile Limited Warranty. The 57-1556 system also includes a powder coated aluminum heat shield to funnel cooler air into the engine for more power and torque.

Owners will be surprised how easy it is to add performance to 2007, 2008, 2009 and 2010 Dodge Nitro models with 4.0 liter engines.
