K&N air filter

[TxGenesis01]

Does the 2015 3.8 v6 carry over the same engine air filter from the 2014? I'm looking into buying a K&N air filter to slightly increase MPG and not have to change filters every 30k miles or so.

I don't know for sure since K&N doesn't list a filter for the 2015 yet, but common sense would say definitely not based on the differences in air box shapes apparent in the engine bay pictures.

Yup, it looks different and they made it difficult to replace. Looks like the cross bar need to be removed in order to access it.

Agreed. It's an odd design.

Changing your air filter will in no way whatsoever increase your gas mileage. Your engine is an air pump, it will still pull in just as much air as it needs regardless of dry paper filter or oiled cotton gauze. It's worth mentioning that K&N filters let far more unfiltered debris in than paper filters do and aren't necessarily freer flowing than some of the better filtering pieces out there (in fact, it's more restrictive than some of them).

Buying and cleaning the filter doesn't really save you that much in the long term either as it's much more expensive than paper filters and a decent sized hassle over simply replacing them to clean and re-oil them. In Texas you should also be changing it more often than every 30k anyways due to the amount of dust out there (Texas native here).

Dont want to get into the debate if it works or not (plenty of that already on the web) but in my personal experience the K&N filter works. I've had them on all vehicles I've owned and they all showed a benifit to my driving/commute. Maybe not as claimed but it does slightly increase hp and mpg. I dont keep vehicle's past 100k miles so i never have to relube the filter and maybe only clean it 2 or 3 times. This keeps the cost down and pays for the 3 or 4 oem i would of needed.

It might up power some, but definitely not enough for your butt dyno to tell a difference. We're talking 2-3 hp on a +300 hp car. Filters make negligible differences, especially on an otherwise stock vehicle (coming from a performance background, this is a universal truth across platforms). Any changes are really just placebo. That being said, you really should be cleaning it every 15-20k miles in most places in TX. And it needs to be re-oiled every time it's cleaned. When you clean it you get rid of the oil, and the filter depends on the oil to do it's job. $60 for K&N filter + recharger kit versus $10-15 a pop for paper filters. You really not saving as much as you think is what I was getting at.

I'll take 2-3 hp any day for a $50 mod that will pay it self over time. Worst case, It will at least offset some of the ac load and yes my butt dyno can tell if the ac is on or off.

Normally i would also add a diablo or hypertech tune but may need to go custom for this car. Not sure if i want to go that route with a v6.

To make life simpler for you, you can not chip/flash this car. You can search the world over and it just isn't going to happen. Unless you would like to spend more money than the difference between the V6 and the V8 or a swap (for a non hyundai engine)

Power or fuel economy, generally you can not have both... without two autos.

Agreed. It's an odd design.

How is it odd? Look at the engine bay - with the addition of the cross bars (added for stiffening which is a nice improvement on the old model, btw), how else would you propose they could have laid this out?

I'm gonna take a stab in the dark and suggest they might have meant odd as in "You don't have to remove a metal brace to get at an air filter in most cars" and in that respect I agree. On my previous car you just pulled two clips (totally tool-free) and slid the filter itself up inside a vertically oriented surround.

I wouldn't have phrased it as the design being odd, but removing metal parts to get at an air filter isn't exactly common from the cars I've worked on.

Funny, auto manufacturers have been busting there butts trying to squeeze more MPGs from their vehicles. If the K&M filters really increased MPG's, and without harming engines, don't you think that they would be standard equipment on EVERY vehicle?

+ 1!

From there web site:

"A lot of exaggerated claims are made in the marketplace by products claiming to improve gas mileage. K&N makes no general fuel economy claims, however we encourage you to try our air filter for yourself. Keeping air filter restriction as low as possible can be an important tool, among others, for maintaining high mileage."

To really improve MPG's automakers needs to start to offer diesel or turbo charged gas engines in a broader range a vehicles. The new Ram diesel pick up gets almost 30 mpg on hwy. Now, why dont they offer it on a regular cab configuration is probably just a marketing strategy to keep people buying extended and crew cabs where profits are higher than regular cab's.

That and CAFE standards apply different rules to trucks!

Odd means different from what is observed usually. Is it that hard to understand or are you being intentionally obtuse?

On 99% of cars you don't have to remove a stiffening brace to replace the filter. Geez.

Odd and uncommon are synonyms......

Never have I ever had to do anything but release a couple of clips on one plastic piece that are attached to another plastic piece in order to get to an air filter.

That's all I was trying to say.

To me, odd would mean putting it somewhere strange without a good reason. As I said, given the addition of the cross bars, I would not call it odd. Where else would you propose they have put it so it would not seem a bad setup to you? I'll take the extra stiffening provided by the cross bars for a few extra minutes to change the air filter any day!

I'm not an engineer and so I wouldn't propose anywhere else. I also didn't say it was a bad setup - you're putting words in my mouth. I merely tried to communicate that it was unusual to have a brace running through the air box in a depression as I've never seen that setup before.

Here's an exercise for you -
Name 20 cars that require you to remove a brace to access the engine filter. Then name 20 cars that do not. Which list was easier to come up with? That's the definition of something not of the usual.

Anyways, I've used K&N cones on my past 3 cars. I've never noticed an increase in mpg or power (obviously a filter isn't going to give you 10% or more, which is the "feel" threshold); however, if you're building an aftermarket intake it's one of the most used filters along with the AEM dryflow.



I'd rather use K&N than one of the knock offs. I also clean mine more often than the 50,000 mile recommendation. I've seen a study that shows that K&N's tend to clog up faster than advertised.

My dad use to have a Chevy Citation back in the 1980's that you had to remove the engine from it's engine mounts to change one of the spark plugs. Now that was a bad design
