Just installed K&N intake on my 2020 Armada. Wouldn't start and stay running. Loooked everything over and was installed perfectly. Took it all off and went back to factory, and she started right up and runs fine. Curious who all has a CAI on their 2017+ armadas and what are you running?

I haven’t used a K&N product for so long. Does K&N still use oil on the filters? If so, it’s possible the filter element may have too much oil and once that oil hits the MAF sensor, that’s when the issues arise.

Yeah, they are an oiled filter. But when i re-installed the factory components and same MAF sensor it all worked fine.

I’d give it another go and check all the connections. Crankcase vent tubes, making sure the MAP pigtail snaps into place. With the MAF sensor, make sure it’s facing in the correct position with the open slot & diode facing the filter and not the throttle body.

oof, solid point on the direction the MAF sensor is facing. Thanks!

I installed a K&N filter on my ‘21 five or six weeks ago and it has never missed a beat. But once you get it running properly, I do recommend resetting the ECU. I learned this little trick from @marctronixx, and the motor is really liking the unrestricted intake now.

Hell yeah! Thanks man! I ordered the k&n that was one step up from the open air box one. Comes in soon and looking forward to putting it on.

What's you gas mileage, where you use the few HP a more free flowing intake provides? You do know that paper filters, filter much better, don't you? You might give up a tenth or two on your 0-60, but personally I'm more concerned about 0-300,000.

Not sure what your question is really……… but no, the stock paper filter doesn’t suck in anywhere near the amount of air a cold air intake system does.

Really? The question is exactly what gain do you get. Can you measure it, let alone feel it? But you're correct, CAIs suck.

Small Increase of HP…….small gain in gas mileage…let’s engine breathe better with the better airflow. Reputable companies have measured these and they are fact. I’ve ran many vehicles with and without them and it is indeed noticeable. Thanks for your valid contribution to the discussion tho.

OK. Where's your hard data for the VK engines? Did you dyno your's before and after? I'll repeat - "exactly what gain do you get?" And unless you're racing (!?!), why does it matter? To repeat, I'm coming from a place where engine longevity is more important than a very slight reduction in 0-60 times. Reputable sources have measured filtering efficiency, and oiled cloth/foam filters are at the bottom. Let me know when an Armada shows up in a Fast and Furious film.

Thanks for repeating yourself and your dislike for CAI’s on a post asking opinions of one’s who ARE running them. Last i checked, improved airflow and a more efficient running engine is very good for longevity.

Got it. You're suffering from confirmation bias, and so are unable to support your claims rationally.

You’re right. None of my other 4 vehicle’s definitely don’t have a CAI and they definitely don’t improve engine performance at all. Or millions of people buy them cuz they do nothing at all. Thanks for your input simpleton.

the injen cai that is for the later model infiniti was designed on my personal qx at the time. with the resonator, stock muff off and a magnaflow, there is no question the car was breathing easier and having a bit more low end torque. this is with stock 22 inch wheels and wider than stock factory shipped tires.

some people like to mod their cars. for someone who references fast and furious films (which jumped the shark after fast 5), youd think you would understand why people like to mod their cars. i drove my qx like i stole it. im not the demographic for the car -- bachelor, no children, but i loved the design and style of the car and hanging out on these forums got me into doing simple mods. with all the emissions controls on these vehicles, it really robs the v8 of its raw power.

anyway, here is a dyno run in second gear on my stock engine. this may or may not be helpful...

Sick man! I hate a stock vehicle and am all about modding them to stand out physically and mechanically. Kudos to you! As for the prior convo……as soon as fast and the furious became the gauge on whether or not cold air intakes were enhancing the performance of the engine i knew the rest wasn’t going to be worth much reply.

K&N posts results on several different models. This is one for the Nissan V8, minor gain, +11 HP, +13LbFt, better throttle response, and a nice subtle roar from the engine bay. I understand that the Armada was made to be a quiet highway vehicle but I like to hear the V8 rumble alittle bit. This did the trick for me. I'll be replacing the B-Pipes and the muffler/resonator too.

@Rick Trexel. Please make sure you've got the MAF sensor installed correctly. Lol.

I too, have always modified just about every vehicle I've owned. Some were heavily modded more than others but IMO, a CAI is always that "first" mod to get the ball rolling. Or should I say, to get that wallet lighter. At the end of the day, a CAI and its gains are minimal at best but it all ties in with other future performance mods.

So... Why are you being super rude? You're in here patronizing someone that's doing something they want to do.

He should be ignoring you but tried to ask a legit question and all you do is be a jerk? That's not appropriate.

If you're old enough to buy a car, you're old enough not to be a jerk for no reason.
