Real Cold Air Intake For 2011 Hyundai Sonata 2.4L

34411 Views 63 Replies 29 Participants Last post by  09 Sonata GLS
Hey everybody, My name is Will, and I've came out with a pure true cold air intake system for the 2011 Hyundai Sonata's 2.4L's. This is not based like the K&N Setup, where they create a simple heat shield and called it a cold air intake. But I've have relocated the filter completely out of the engine compartment, in to the drive side wheel well. I've created the prototype piece, and it's working wonderful. The sound, throttle response, and just the smoothness of the power curve is amazing. I've also have dyno graph of the unit, but will put it back on the dyno in a week after the car settles the unit in. Here is a teaser shot the unit, showing where the filter is now located at. I'm planning to make a bulk made, wondering how many people here would actually be interested in this unit... Thank you for you time looking... =)

nice!! i think i'll try that. i purchased a k and n cold air intake and it heat soaked me to death. i lost power until about 3500rpms. u made a true cold air intake. good job keeping the pipe short. where diod you buy your piping. i need some but i have to make sure i will get the right stuff. you know how ordering can go. i wasted 300 dollars on that k and n. i quess i can use the filter boots and adapter. how did u install the vac lines? did you drill and/or weld them
its a possibility (if compatible) need to see more pics and test results

for my intake system, it's in pre-production mode at the moment, everything you need, the coupler, pipe, filter, vacuum lines, the t bolt clams, everything is going to come in the kit, the price for it yet is still determines on the quantity i asked to be made, also i will post everything when the system is final, showing dyno graph, to install pictures, to how the system looks, when i get the pre-production kit, i be doing lil more testing, and test fitting. so please hang tight for a short bit and i'll keep everybody posted.

compatible to which year sonata, and test and pictures will be posted very soon
i just wanted to keep everybody posted, the pre-production unit's are coming in this weekend, i'll post some actually finished pieces, and we would be doing more testing on these, and i shall post them up as well... =)
looking forward to it
could post video clips etc, as well? thanks
i'm sorry everybody, i have been m.i.a. on the forums for a short time, it's cause i'm in still in progress in getting my intake productions, there was a company that was hired to manufacture the intake, but fail to meet my needs on quality. so i had to cancel them out, and find someone new. they are now in process on making the intake, and will find out a eta around by the end of this week, when i should have them to the public.

don't worry i didn't forget people in the sonata family, dyno results, to video post on the dyno, and finish product images will be posted in a very short time.

and head's up, i've came out with another intake for the 2.4l sonatas. this is a factory airbox upgrade. it's being tested now, and the owner of that car already say's that there is a day and night in throttle response, and engine hesitations are gone. while he say's he's getting 15-25 more miles per tank, even that he's driving habit's have became a little more aggressive. and his main key, is that he didn't want to make the car any louder then factory, and the noise level was as close as factory.

here is a sample picture of the factory upgrade.

The picture you are showing is for the factory airbox upgrade correct? And not the cool air intake system right?

Are you manufaturing these in Japan directly? Just curious.
I must respect those who think out of the box. Good stuff.

Now, in order to replace the filter....you would have to remove the front bumper?

the picture was a sample of the factory box upgrade, i'm actually just waiting on the finish product from the manufacture to come to me, so i can post a complete kit and show everybody.
and the product's are not being made in japan, they are being built in california. =) made in the USA

to replace to filter once the cold air is in, the removal of the bumper won't be necessary, all you have to do is remove 2 plastic clips on the slash guard, that will open up the position where you are able to reach the filter.
I really don't understand how this would benefit vs. a factory intake.

I don't believe there are open vents that would allow air to flow into the front fender well. If you have a GLS I guess you could cut or remove the filler where foglights would go, but I doubt anyone with foglights would want to remove the foglights.

Also, the factory intake has a front vent that allows fresh cold air to flow directly into the intake.

Its all about the velocity of the air going to the engine. The OEM tube has ripples on it. If it had smooth piping, the difference would be minimal. Smooth bending pipes plus a less restrictive filter will gain more hp, simply because you are getting more air into the engine. That is why even a short air/warm air intake would gain a few hp.

Location of the filter is mainly to draw colder air instead of sitting in the engine bay. You wouldn't necessarily need to "force" air to the filter. Once you get moving, air would go up there anyways, because its not completely sealed off... at least that's the case for the NF.

to answer you question, the benefit on my unit compare to the factory unit, is the factory intake is sucking from front of the car going through to the air box, get filtered, then coming around going through the non-smooth intake arm, that has a 2nd filter, and into the throttle body. but my cold air is taking air from a different area, though a smooth angle pipe into the throttle body, so the movement is more instant and less resistance, and with the slight bigger piping then the factory, allow the unit to work at it's full potential.
on your theory opening up the foglight hole for the gls models, will be beneficial when the vehicle is moving, just the same concept as the factory ram air idea. only work when the car is going high speeds to feed the car.
as for me not following idea's like the k&n intakes, is simple. having a open filter up by the header locations is just pointless, even with a heat shield. cause the car is always generating heat, i took the location of the open filter, and relocated to a area where there is no heat, and can provide cooler air. cooler air + efficient movement = more power

you got the idea ricerR =D...

Hey everybody, it's been a long time, but it's about that time my cold air intake's are going to be on the market. They are in the final step's on completing my system. I'll be uploading pictures sometime next week, when the manufacture gives me the sample production unit to finalize the product, and do a final test fit. But giving you the head's up, the pipe will be in a wrinkle black powdercoat, all the hoses and couplers will be in black also, and the filter I'll be using is a AMSOL / INJEN dry flow filter. Reason I choose this filter, is the design work, and quality was in my standings.

Also I'm going to be testing the water's on this idea, I've posted this on Hyundai-forums and I wanted to see, if I give you guy's here the opportunity to get on a group buy on my intakes, before I release them to the wholesalers. The MSRP on my unit's are going to set at $240.00, I'm willing to sell the unit's to you guy's at special price at $230.00 (Shipped). If I get more then 5 people on board, the price will drop to $220.00 (Shipped), and if I do get 10 people on the list, price will drop down to $210.00 (Shipped). For a cold air intake at $200.00 is really cheap, please let me know what u guy's think.

And as soon I have the final piece in my hands, I'll post pictures. I'm in process on posting the video's of the car on the dyno, it will be up soon. =D...

Thanks everybody for being interested, and I won't let you guy's down on the quality, and R&D on my units.
