The K&N 77-6014-1KP Air Intake fits some Nissan Frontier, Nissan Pathfinder, and Nissan Xterra models. See vehicle applications link for details.
The K&N 77-6014-1KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Nissan Pathfinder, XTerra and Frontier 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 77-6014-1KP 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 mass air sensor and a replacement silicone 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 couple of screwdrivers, pliers, a ratchet set and some 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.

K&N 77-6014-1KP Air Intake Product Reviews

Saturday, August 11, 2018 - Part 77-6014-1KP
I purchased the cold air intake for my 2017 Nissan Frontier. Unfortunately my truck did not seem to like using the cold air intake. I started to have the engine pinging after about a day of having the cold air intake installed. Then after about a week, the check engine light turned on. I removed the cold air intake and put back on the stock air box. The check engine light went away and have not had a problem since. I did have the code checked when the check engine light turned on. It came back having an issue with the mass airflow sensor. I gave this a 5 star rating because I contacted K&N due to the issue I was having. They asked me a few questions to make sure there were no manufacturing defects. Once all questions were answered, they told me they would issue me a full refund. They did this because my truck was not being compatible with the cold air intake. Exceptional customer service on their part. I received a full refund in less than a week. Just wish the product would have worked with my vehicle.

Easy install It seems I have noticed an increase in power and it does sound the same but as to a mpg increase I can't say as of yet, it does look pretty cool.
