The K&N AirCharger 63-6018 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-6018 air intake comes with a large chrome topped K&N high-flow air filter and a heat shield that installs into the factory mounting points. This allows cooler, denser air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized 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 using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

K&N 63-6018 Air Intake Product Reviews

Friday, September 14, 2018 - Part 63-6018
Good morning K&N Team, So far so good I love the new filter assembly that I personally installed on to my 2015 Infiniti QX80. It gave a deeper, slightly louder but bearable growl to the engine. As far as the HP is concerned I cannot comment, I will just have to take your words for it that the K&N system adds an extra 10hp from the already factory 400hp. I'm hoping to place the SUV on a dyno in the not to distant future. Cheers, Tony. T
