price is $423 though:confused0068:

You can find it for cheaper on other sites. Around $350, still pricey though. I wonder how much the gains are.

Uses factory air box, which was actually something I was interested in. Simple glance at the factory setup shows decent design, but slight improvement in intake turbulence reduction from trashing the ribbed pipe from the box to the tb, and the resonator bs.

is there any pics of the install ?

I would trash the resonator connection and just plug it though.

Looks interesting...mind my ignorance because I've never had a car with a boxer engine before, is this the closest to a CAI set up? I was thinking of just popping an HKS 3 layer air filter in the stock box and call it a day for now.

Without replacing the whole assembly, yes.

Those HKS mushrooms are noted for being HUGELY inefficiencent. Supposedly one of the worst aftermarket filters money can buy, so much so that it has been nicknamed the "death shroom". All it is is a piece of coloured foam.

Plus, without moving it to cold air, all its going to do is suck in hot engine bay air. You'll actually be worse of with of these as opposed to your stock arrangement and obiously $350-$450 poorer.

i don't like how they left that piece open :( and why did they connect the stock unit on...i thought it came with the mushroom filter..??

The shroom is inside the airbox, but technically since it uses the stock airbox, you could use whatever drop in filter you wanted....instead of the shroom.

Overpriced and underdeveloped... will probably sell great!

They sell many different variants of filters. Some thin/thicker and the size can change as well.

I'm guessing this HKS intake is getting air from the same area as the stock one, so it should be cooler air then the engine bay

^^^^ i agree

They use to disintegrate too. Hopefully they fixed tht issue.

Has anyone made a good intake with velocity stacks yet? Or just a bunch of filters on a stick?

Ooooh.. it's so shiny and says HKS on it!!


I swear I'm in the wrong line of work... I need to start making aftermarket parts in stainless steel or carbon fiber with a fancy logo on them. Clearly you don't need to improve actual performance to sell parts...

A problem with this design is that unless it removes the factory horn and replaces with something else, its not picking up the HP it should. It is a little pricey in my opinion for a pipe.

We gained 1-2hp regularly by removing the bumper horn alone.

Typical simple pipe and filter like almost everyone else is doing.

With absolute no R&D behind it. :thumbdown:

There are some really nice items in development that will be released in the very near future, the smart people will wait. This is a perfect example where the saying "patience is a virtue" plays a huge roll. ;)

So HKS isn't doing R&D? :-/

Take a long look at pic on post #15. Where is the R&D? It is in the fitment and looks of a shiny pipe to replace the stock rubber pipe. Really?

Yep, HKS certainly doesn't know what they're doing. What are they lacking in design? Atleast they aren't putting the element in a hot engine bay. It works. Doesn't need to be a ground breaking reinvention of the air cleaner assy...

So, what would you do differently when designing your intake? My reply was to suggest constructive criticism instead of knocking a premier Japan tuning house.

" The HKS Premium Line of Suction kits are for those who want maximum performance out of their intake system, but do not want to change any of the intake characteristics. This particular kit keeps the factory air box, replaces the factory air filter with a high flow foam filter, and replaces the factory plastic intake pipe with a hard pipe."

^ Their intent was to keep it simple. They suceeded.. :)

From what I can tell...


That's the equivalent of saying an FRS priced at $40k is worth your respect and support because Scion reached their goal of making a simple car. The stock piping probably does the job 95% the same as the HKS job here and it saves you $400....?

What?! Lol

No body is forcing HKS intakes on anyone. If it's too much $, don't buy it. My initial reply was to ask what R&D was missed in their successful attempt at making a replacement pipe and conical filter inside the oem box.

In other words. They have created a simple "intake" replacement.

? How do they put the filter inside the airbox while simultaneously using that billet MAF housing? They'd have to plug the OE MAF boss on the filter box. As far as I can tell that's just a short ram straight off the front of the motor. Similar to the design we've prototyped but we're running a shroud to the factory inlet as well. And no turbokillerdeathshroom filter. HKS makes some great products. Their intakes have never been known for being great. They're car jewelry.

As for the questions about an air horn vs. a filter on a stick, most decent conical filters on the market have the air horn feature built into the outlet flange on the filter.

Was just going off of what was shown as well as parts in the kit. I did see the exact same kit on another site with a drop in filter instead of the shroom, but looked to be that same sponge filter material...

Oh, where to begin, my post definitely did not say that HKS does not know what they are doing.
Quite the opposite, they literally took less than an hour designing the intake for this car, using the stock MAF housing and filter box ensures them that the A/F will be unaffected and keep their cost extremely low.
Replace the stock filter element with a fallapartincoupleofmonthsfoam element, slap on an HKS sticker put it in a pink/purple box and tell you this the the "maximum performance" out of an intake system, but it is HKS so you will pay a premium, bend over and smile at the same time. They definitely know what they are doing!
First of all let's clear something up very quick, their intake is a replacement PIPE for the stock "System", it is not an "Intake System". (needed to get that off my chest")
Every consumer should ask EVERY manufacturer for R&D data, (good manufacturers will provide this data without you even asking for it) just like people demand dyno charts with A/F graphs from every other company, HKS should do the same. Let's see their R&D data, if they do not provide one then no proper R&D was done for this particular item.
On the other hand HKS does make some really nice products, we have been and continue to use them.
As far as what we would do differently, well, wait a couple of weeks once we have actually finished our R&D we will make a nice post with all the pictures, videos, dyno, A/F charts etc. :D



No, you are wrong! We are talking about the HKS "Intake System", you pay your US$ for my JDM parts! NOW!!! :popcorn:

Any my initial post was what R&D was actually performed to create this "simple" "intake system" that demands $$$$

See below.
I believe that there is confusion as to what exactly is available from HKS is it a short ram style intake or a replacement pipe with a drop in filter element.

Modern day fuel injected engines really don't need aftermarket intakes for performance. The stock one developed by the engineers are actually pretty darn good these days. Also, it has metal plumbing, which will retain engine heat more then the stock plastic plumbing, and increasing intake temperatures. That is not something you want, and probably will hurt performance more then help. Also, modern day mass airflow setups seem to be quite picky, and adjusting the plumbing from the stock setup could affect A/F ratios.

I think all you need is a good panel filter (like the TRD one). I still have the stock air-box and intake plumbing on my WRX, and have the STi panel filter. I plan on keeping the stock intake setup even after I throw on a bigger turbo and intercooler, etc... because the stock one is pretty darn good and can handle 400+ HP without issue.

This really depends on the car. Our intake on the Kia Optima Turbo (Speed Density from the Factory!!) makes 11whp/13tq over a baseline with a panel K&N filter (and it uses the panel filter - just the piping for the intake makes 11/13). Most intakes and turbo inlet pipes on Mazdaspeed3's crest over the 25hp mark. A simple cat delete and intake I designed for the MS3 at my last job made 52ftlb of torque. Just depends on the car really. Our intake prototype for the STi makes quite a bit of power with the proper tune, where the factory unit gains less with a similar tune. N/A is a whole different story - much harder to build power, but most people want a good sound on the car and induction is always a fun direction to go for that. I dig the speed density cars, you can run a massive 3 or 4 step reduction from a 4" filter to a 2.25" throttle body or turbo inlet and really build a lot more power than stock.

As for MAF tuning and getting the diameter and MAF placement right, it is very finicky. After designing 7-8 different setups though, you get to be able to intuit a design. Some simple computational flow dynamics software also helps. I was working with my old employer on the Mazda SkyActiv MAF housing design for their new intakes and I was able to get within 3% of our long term fuel trim goals on this first try. That was with a billet MAF housing, which is pretty much necessary to get repeatable results. Welded MAF bosses seem to be a good way to induce variability into a system like that.

Also, your comments about metal vs. plastic are not terribly accurate. I've done the tests back to back with four channel thermocouple dataloggers and there is negligible difference (standard deviation at best) between stainless, aluminum and plastic or rubber. All heat soak over time in the engine bay. And even at wide open throttle with an office full of air being ingested by the car every few minutes, the intlet air temperatures of an intake drawing outside of the engine bay air doesn't change markedly by a material change at the intake. That may be different if you had, say, a 32" long .25" wall aluminum intake, but stainless or silicone vs. thin wall abs is functionally a wash.

N/A cars are most certainly a hell of a lot trickier to make power on an intake. It's not to say that many of us aren't up to the challenge though. :thumbsup:

Would be so much cooler if there was no MAF. Speed Density FTMFW!

^Coming from you, it actually means something. Nameless is one of the few companies with a good reputation that I actually notice.


Like you said, depends on the car. I have probably been immersed too much in the WRX crowd on the very heated debate on whether the stock intake or aftermarket intake is better. However, i still cant bring myself to trust a metal intake... :(


I was thinking very similar to the MAF setup.


Thanks for your explanation.

How do you even state this as fact? Do you work for HKS Japan? :)

If someone wants to pay the price that's their own business. I personally like brands like HKS and ARC. People used to bitch about their costs too.. But, again, nobody is forcing anyone to purchase the parts. We should be happy there is strong support from companies such as HKS.

I hope you do offer a nice kit and I'm not knocking your ability. To be honest you are coming off as pretty rude or harsh about it. :) It is an intake kit. It provides a metal pipe and filter for the oem box. Some folks actually want this style.

This is perfect (i.e. do a noise generator delete). The sound will provide a bit more growl.
