K&N 05-07 Jeep Grand Cherokee V6-3.7L Performance Intake Kit

If you're looking to get a bit more pep out of your 2005-2010 Jeep Grand Cherokee with the V6-3.7L engine, this K&N performance intake kit is a solid option. It's designed to help your engine breathe easier, which can lead to a noticeable improvement in how it performs, especially when you need to accelerate. The kit replaces your restrictive factory air box with a smoother, larger diameter tube and a high-flow air filter.

The main tube is made from high-density polyethylene (HDPE) using a rotational molding process, which helps increase the volume of air that can reach your engine. This, along with the oversized, conical, oiled cotton-gauze air filter, is what K&N guarantees will increase horsepower and torque. The filter itself is washable and reusable, meaning you can clean it and put it back in service, potentially going up to 100,000 miles between services under normal highway driving. A custom heat shield is included to help keep hot air from the engine bay away from the intake air, ensuring your engine gets cooler, denser air.

Installation is typically straightforward and can often be completed in under an hour, making it a manageable project for many DIYers. K&N also backs this kit with their Million Mile Limited Warranty, and it's designed not to void your vehicle's factory warranty.
