K&N air filters for my 2015 Genesis 5.0

[J Dixon]

Have run, and will continue to run, K&N filters in several vehicles. The only vehicle I noticed an appreciable difference in performance was in my Dodge Ram (this K&N FIPK is actually shaped like the old Moroso air filters we used on 4-barrels). It greatly increased surface area, hence more flow. Even so, it was a small increase but worthwhile.

The 5.0 drive by wire seems the biggest hurdle to me.

AMEN.

The sprint booster is actually supposed to get the butterfly to open faster than flooring it.

 

[Alfer]

YES!

And I know how ridiculous that sounds. But it's all about perspective, my friend. There is somewhat of a lensing effect when it comes to speed. At the speeds we are talking, yes you'd feel the difference between a 4.7 sec car, and a 5.0 sec car. IF those cars would race, the 4.7 car would win by about 50 feet, or 3+ car lengths. That, you'd feel.

This is why people in the 10 sec 1/4 mile and faster range fight for 100ths of seconds...

Funny how the brain is so easily fooled.

 

[carguy75]

LOL! So you are claiming you felt the tenth of a second change??

I am not going to say that I can accurately measure exact changes in acceleration in my brain, but I did perceive that my Genesis accelerates quicker with the K&N performance filters than it did with the stock filters. I stated as much at the start of this thread.

The Torque Pro GPS data reinforced my perceived observation based on other actual acceleration tests that was done on a stock 2015 Genesis 5.0. GPS data is more accurate than my butt-dyno, but my butt-dyno did noticed a change in how the car moved even if it could not state that it was an exact 3/10th quicker.

What is your foundation for these comments? I am curious, what makes you so certain that a person can not perceive a small change in acceleration? Can you post any supporting information to your claims other than your cynicism?

 

[Alfer]

You bought the K&N for the sole purpose of increasing performance and you were convinced it would work since you invested good money in it. So when you switched it out and tried it you mentally convinced yourself that there WAS a change you could notice but in reality, nobody could tell that there was 1/10th of a second change in any action you did.

Don't feel bad. Same happens with folks who buy into the whole audio/video cable myths. Meaning, you buy a $1000 HDMI cable you then convince yourself that it is indeed creating a better image on the TV vs. say a $10 one from Monoprice or other name brand makers. It's just how our brains work.

Again where is your proof that a person cannot notice changes in a car's acceleration. You are still just posting your opinion. Are you some sort of expert on how a person mind works?

If so, post creditable information to back up your statements.

Note: the change is 3/10th "4.7 seconds vs. 5 seconds."

you buy a $1000 HDMI cable you then yourself that it is indeed creating a better image on the TV.

i prefer to spend my hard-earned money on worthwhile things...

Oh, now you've really backed yourself into a corner. You may not trust Carguy's butt-dyno, but numbers don't lie. So, either you're saying the 2015 5.0 Genesis can run a 4.7 sec 0-60 mph stock, or the K&N filters made tangible gains... Which one is it???

 

[Suburbazine]

Um.

Why has nobody pointed out that he measured 0-60 time in tenths of a second using a GPS receiver with a 1 second polling window and up to 2 seconds of variance on top of that?

And anyone who thinks 4.7 seconds is possible on filters needs to leave fantasyland before posting. Butt dyno has no value on numbers. I could make an exhaust leak on the manifold and you'd think you had more power by sound alone...

Horsepower determines 0-60 time. You don't get decreases in time on a certain platform without significant power increases. It's something beyond the realm of intake filters.

It doesn't matter 3.3tt or 5.0....both cars are almost the same and weights ~4600 lbs. Both are rated ~5.0-5.1 0 to 60.

Both my best runs are below...

1st one with JB4 Map3 93 octane - 382whp/462wtq ....so with ~10% of powertrain loss, the HP/TQ would be ~420/508 4.68sec
2nd one with JB4 Map5 E85/93 octane - 414whp/481wtq..... ~10% of powertrain loss, the HP/TQ would be ~455/529
4.42sec.
Oh, my runs were "valid" by Dragy on almost flat road. Not sure about yours, it could be ~3%+ down the hill, your butt-dyno won't tell us that, lol

 

[Suburbazine]

^^dragy is legitimately 100x the accuracy. Granted it has a potential 0.2 second skew but it also internally certifying, so it's still trustworthy when used.

Great freaking runs, dude! Thanks for sharing some hard data. However, comparing the acceleration of a N/A V8 and a TT V6, is about as apples to oranges as you can get.

The Draggy has been tested multiple times at the drag strip and has been prove to be accurate within a few 100ths of a second. I 100% trust Carguy's 4.7 sec 0-60, but I have to agree that no way he got that from the filters alone. The filters + the Sprint Booster set to "LUDICROUS SPEED" would definitely do the trick, though. Its no secret that Hyundai tuned the 2015+ Genesis Sedans for smoothness, that includes the power delivery. That smoothness is achieved in part by the drive-by-wire throttle body being programmed to open and close in a smooth, and slightly slower fashion.

0-60, like all acceleration, comes down to a lot more factors than just horsepower. Throttle response, torque and torque curve have a lot to do with when and how fast the power gets delivered and has a significant effect on 0-60 times.

Carguy isn't using a Dragy though. He's using built in GPS and an ELM adapter.

Also, sprint booster does nothing to modify throttle crack time or swing speed. Sprint booster 100% is exactly the same as pedal 100%.

You sure about that...?

 

[Suburbazine]

Yes, I'm sure. And getting a video of two talking idiots who are paid to promote a product isn't a valid supporting fact. The fact that I even have to point out that they pushed the pedal super slow to illustrate stock opening speed, then slapped it down to show how sprint booster "makes it faster"...

It does nothing that the gas pedal doesn't do already. The only thing is simulates is having a shorter pedal throw. And showing the throttle blade opening to 100% at 50% pedal travel then falling off isn't good for business.

Spoken like a true skeptic. There's a lot more reviews out there, I just picked the shortest one. They can't all be fake.

IF the Sprint Booster works as advertised, you gotta see how that's worth its weight in gold.

Carguy75 I also took out the stock air filters within the first week of having my car and replaced them with K&N Air filters. Whatever the difference is, it really doesn’t matter. Better air flow so obviously it has to make some kind of difference, even if it is a small one. I don;t think it should matter if you did or didn’t, as long as you are happy with it, that’s all that matters. Enjoy!!

Yeah, a lot of positive reviews who butt dyno and assume that less pedal for same power = more power. All of them, bar none, are clueless about how cars work. Might as well add a splice in MAF "ecu tuner chip" while you're at it to experience all the gains of modern electronics hocus pocus. By the way, I've heard rave reviews about curing people from the flu by bleeding them until near death.

Sprint Booster – Is It Worth It?

http://www.crosslake.net/~dbipes/sprintbooster/SprintBooster.pdf

I'm not a skeptic, I'm an automotive electronics technician. You see two wires, I see the entire thoughts of the car going by. There is nothing you can plug into a throttle pedal wire that will improve power. Nothing (but you can definitely reduce power). It has 2 or 3 independent but synchronized states that move between a fixed upper and lower limit. There is no way to artificially extend the range by adding electronics.

Fun fact: 100% throttle demand is 88% throttle actuation (give or take 5% depending on engine design). No matter how fast you hit 100% you only get 88% out of it. Engine makes more power by not opening the blade all the way.

 

[carguy75]

Oh my goodness. This becoming too much.

First, I want to only read valid observations from another Genesis owner who also tested a 5.0 engine stock and with the K&N air filters with any type of GPS measuring data to back-up the claimed results. I do not want to keep reading any negative feedback based on different model Genesis like the 3.3T tuned or stock, different engines and drive-train so not really comparable. Weight does mean anything since the Genesis G70 is lighter than the Stinger, but the Stinger is about 3/10th faster in magazine test even if both has the same 3.3T engine.

I actually performed my acceleration run going up hill at the end while turning left and right around corners, so the road was not in the Genesis favor.

Car and Driver used 91 octane for the 2015 Genesis test which makes 420hp per Hyundai, however I use 93 octane so my engine probably making more than 420hp in stock form due to the higher octane so my stock 0-60 times may be quicker than what Car and Driver made as well. However, this all speculation on my part since I did not dyno the engine nor do a measured 0-60mph run with the stock filters.

All I know is that I swapped the sad looking stock air filters for K&N performance air filters and noticed an increase in performance right away. I measure the car's performance and the GPS test data also reinforced what I felt from the driver's seat. I got 4.7 in ECO mode on a curvy road going slightly uphill. Therefore, I believe that the 2015 Genesis is much quicker than 4.7 seconds with a good launch in sport mode with performance filters. Have not had time to test my theory due to traffic and rain.

It would be nice for an actual owner to provide a measured base line for a stock 2015 Genesis 5.0 model so we can actually get an good understanding of what the car can really do in stock form besides the one pre-production test car Car and Driver used in 2014. For all we know, a stock 2015 Genesis can do 4.7 seconds in stock form with 93 octane fuel. The car is actually not really tested outside the pre-production models nor with 93 octane fuel.

Most of these negative member commits are just based on limited information. I would understand major resistant to me posting times that goes against other measure times provided in the forum, but no one else really tested the 2015 5.0 Genesis aside from myself. All the negative statements are just opinions and speculation based on subjective thinking.

I ran a 4.7 0-60 time in ECO mode, so the V8 engine is quick with K&N performance filters and is probably much faster in Sport mode, so get over it. I understand that someone spend $$$$ to make a 3.3T faster than V8 and wants to feel that the gains are much more but is probably not it seems.

So unless, someone can post some actual 0-60 times for the 2015-newer 5.0 V8 engine than keep your negative commits to yourself please if you already posted them once, unless you have proof to go along with them of what a 5.0 engine can do besides magazine articles of the pre-production model.
