The K&N 77-1538KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Dodge Durango models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-1538KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory air temperature sensor and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

Customer Feedback

This is my second cold air intake system from K&N. Could not be happier. This one is installed on a 2011 Dodge Durango Citidal, 5.7 Hemi. The sound difference is amazing. Now it sounds like a Hemi. It's only been on for 1 day so I do not know about the increase in gas mileage but I have noticed the increase in throttle response and improved horse power. I would recommend these intake systems on any auto. A definite must buy.

I have a rather large head and K&N is the only place that I have ever found that carries a hat that fits me well. The hat is also a quality product. I also like wearing the hat because I installed a K&N cold air intake system on my 2011 Dodge Durango and I love it!

Installed this on a 2005 Dodge Durango with the Hemi a year after buying the vehicle new. (has been on the Durango now for over 7 years). First thing you notice when removing the OEM air intake is all the extra sound dampner boxes and restrictive passages. The K&N is a large near-straight tube taking air directly to the throttle body. Has a nice large filter. Kind of a pain to get it off to clean due to being squeezed into a tight space but do-able. Once installed and I started up the Hemi it rev'ed up super high due to all the restriction being taken away (what it was use to). I then took it for a drive and it was night and day improvement in response and extra power. Took a week or so of driving and the computer adjusted and optimized to the new intake. Saw a tiny improvement in MPGs. The power & sound is awesome. When you get on it it really growls. If you drive conservatively it is near unnoticeable. Have had no issues with it over the years and filter has held up great. I would get it for any Hemi vehicle I own in the future.
