01 QX4 Cold Air Intake

[KyooX4]

I know most pathfinder parts are compatible with QX4s of the same year, and I did some searching here but I'd still like a definite answer. Would a K&N Cold Air Intake for a 01 Pathfinder fit an 01 QX4?Here's what I'm looking athttp://www.knfilters.com/searc...-6011

Anyone?

i dont see why not...if there is any difference under the hood between both cars its probably the infiniti badge on the engine cover and the extra wires for the HID lights and Intelligent cruise control which im pretty sure wouldnt get in the way.

should be indentical

Besides increasing accelaration, what else do cold air intakes do? Are these things noisy? I've heard of performance parts like this sucking more gas as oppose to decreasing usage. If so where can I purchase a cold air intake? I'm newbie when it comes to performance parts.

Primarily a cold air kit will increase horsepower (somewhere around 14.5HP) in high-end RPM's (around 4000 or 5000 RPM's). The increase is most noticeable on the highway at high cruising speeds.

They will suck more gas than usual because you will want to punch on the gas all the time haha

They won't actually decrease your vehicles MPG. They are said to increase a vehicles MPG, but even if it does, it's a negligible amount because I certainly have not seen an increase in MPG.

Cold air kits will increase under hood noise, mainly during acceleration. You are essentially moving the intake from the driver side fender to the engine bay, so it will be noticeably louder. This is, of course, a good thing. And no, this does not increase cabin noise.

I recommend upgrading to a cold air kit mainly because of their cost savings when compared to standard air filters. I can recharge my filter once a month with the recharging kit and the kit will last roughly six months. That's about $4 per month (the recharge kit is about $25 I believe). This will also ensure that the engine is running at peak performance. K&N recommends recharging the filter something like once a year, which is crazy.

There are MANY different brands which you can buy, all of which have a wide range of pricing. There are pre-molded systems and then there are form-yourself systems. Pre-molded means you just pop it on and you're good to go. Form yourself systems are basically a bunch of pre-bent pipes which allow you to form the intake tube yourself.

If you are cleaning and oiling your K&N filter every month then you are wasting your time and money, and not getting good filtration. K&N calls for cleaning it every year. I do mine every 6 months because of the dusty off-road conditions i drive through, it gets dirtier way faster than average. You should do a visual inspection of it. Only clean it when its visibly dirty. It should even change colors (to brown) when its dirty. You WANT some dirt to be in the filter - its the dirt and oil working together that actually do the filtration. A slightly dirty K&N filter actually cleans air better than a freshly washed and oiled filter. if you are constantly washing your filter, you are allowing particles and dirt to get into the engine!!

K&N also says that you should not clean your filter more than 25 times or the cotton filter media can become to worn to filter effectively. K&N is supposed to last the life of your car - NOt only 2 years!!

Yeah I don't actually recharge it every month, I was being a little facetious. I do recharge it about every other oil change, or every six months. It never really gets dirty in six months tho.

The good news is that it is covered under the lifetime warranty, so if it wears prematurely they will replace it (I'm pretty sure).

I've had several parts on the kit break (accidentally by my hand) and they overnight a new part with no questions asked, it's awesome.

Anyone do this with a 2000 qx4?

I usually do clean my FILTER about once a year or like every ten months or so.. The reason being is I don't drive my truck much and I don't live in or around a dusty enviroment... From the picture you can see It's time to clean up the filter...

What is used to clean the filter? Do you have to snap off the cone itself and just wash it?

[Fafdawg]

This is what i use to clean my filters...I have two, I keep one clean, when it's time to change i just swap and clean and keep til next time. Hope this helps.
