The K&N 77-1561KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ram 1500/2500 and Dodge Ram 1500/2500 Pickup 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 77-1561KP 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.

Review part 77-1561KP
Saturday, November 14, 2015 - Part 77-1561KP
Once installed, great performance increase. The instructions were not clear if you have a newer truck, as there are 2 different air box configurations, it takes a little figuring out on your own. There was also extra hardware that I could not figure out what it's for, i.e.: round aluminum bushing. Not even listed on the parts inventory.

Awesome product. Installed it in less than an hour. Paired with a new exhaust, I'm getting four more miles per gallon on my dodge 1500. Definitely a must have for any gas guzzling truck.

Well I can say that this cold air intake looks great, sounds awesome, but no difference in the horsepower. I have gained a little in MPG, 1.5. Had to modify the vent line for the crank case. The hose provided was way too small. This is on my 2014 Ram 1500. Overall I like it when I put my foot into it. Thanks. Love the sound, reminds me of the days with carbs,and four barrels 77.

Easy install.... looks and sounds great... This was my first install because the local shop wanted $150 to install and since I'm now retired I felt like I could do it myself and so i did... Thanks.

The kit I received was complete, the installation was easy and the instructions were complete. Everything was there for the installation, the fit and finish was excellent. It SOUNDS AWSOME and you can feel the improved acceleration. I have run K&N products for a number of years and am very satisfied.

The directions with the kit were excellent and the pictures provided good reference, so installation was a breeze. So far I like the performance of the product very well.
