HKS Intake duct.
 

Do you like cheap/effective/stock-looking parts as much as I do?

Then check out this air intake duct from HKS.

I just ordered one. $215+ sales tax NZD shipped from HKS Japan.

Generally, I've found that I generaly spend anyway from 50% - 100% more than US based guys for parts, because the NZD forex rate is weaker, and often I have to buy things from Japan as no supplier really keeps much stock for 86's in NZ, as the car isn't common enough to justify this.

Based on that, its quite feasible that US based guys will be able to get this for somewhere in the range of $100 - $150 USD :D

No eta yet. They're out of stock. Will post more pics / review when it arrives.

This unit is MUCH better than the other air intake duct currently being discussed. (Disclaimer - my opinion)

It does look like great value. I look forward to pictures and your driving impressions.

Just placed an order for one from Japanparts.

Just kidding, they're backordered until September haha.

Wait a minute... why didn't you just cut yours to look like the HKS and then bond another plastic piece for the same effect?

Because I'm not Mexican.

This is possible but it would be very hard to make as nice a intake as a molded one. Cutting and bonding tends to end up with sharp or rough edges etc.

For anyone in Australia/New Zealand, NST are selling these :)

I would have to see how much horsepower this made before I would label it either cheap or effective.

Don't buy it then.

Since when did $150 become 'not cheap'. :bonk:
I'll review the product, but I won't be doing a before and after dyno run. Spending $300 - $400 of my own money to justify a part that I already have purchased, isn't going to happen.

TBH I couldn't care less whether it gave .5hp or 5hp. I think its a better design that the stock item, which is why I am going to use it.

It looks worth it just to remove the resonators in the factory snorkel.

lol!! I'm mexican!! I was totally thinking, "that's a good idea!! Where is my duct tape!?" :happy0180:

Props to be installing this, I look forward to the review. I will be buying one as soon as funds allow :D a bigger opening can only help IMO

What are peoples thoughts on the 3 hole on the top near where it goes into the airbox? Good feature or whould you seal them up?

That would be a much more cost effective way to get the same changes in intake sound and the same lack of hp/tq gains.

how much $$$??

It's JDM!!! If you have to ask.....

Thanks for creating a separate thread. I feel I thread jacked the Max Racing one just a bit by posting pics of the HKS one. :lol:

All that I can think of is to dump any air pressure so it doesn't confuse the MAF sensor and stuff up the mixture?

Not exactly sure if it works but essentially the theory I'm getting from the translation is since the holes are at the top it will reduce the chances of hydro-lock in flooding or inundated conditions.

I left that one out to aviod being abused and the top edge of the intake is so high it would only work for a very limited level which would probably write the car off anyway as it floated before sinking.

Thanks for posting this... I just got a great idea for my next mod... :)

Yeah what's up with the three holes?

But seriously, I wonder how much removing and plugging those resonators would affect the sound/ anything

order an extra one and find out :iono:


Im assuming for water removal. I think that is one of the main purposes of the resonators aside from... well.... resonating.

I always though a velocity stack design was the optimal design for high flow (which is what the stock tube is). What's the science behind this being better on a stock engine?

I'm part Mexican too, but I refuse to reinforce the vehicle stereotype.

Lol. Me too. It was funny though ;)

That's awesome. I'd rock it. If I'd find a good molded duct to the bumper it be a nice add on.

Which seems odd. I would think extra air pressure pushing through the filter would be benificial.

I also read that. If you're driving through water that deep i don't think those three little hose will you help much.:iono:

I have removed all the resonators from my intake. I did it progressively as I modded. I can say that removing the resonators one by one you can definitely hear the difference and which rev range they were each designed to quiet down. The ones in the snorkel were more for the top end. :thumbsup:

In theory the extra air pressure is great for the engine but with no MAP sensor to measure that pressure[I'm assuming?] the MAF sensor measuring flow could result in a weak mixture. With higher pressure there is more air going in than the MAF reads so the extra fuel isn't supplied resulting in a lean mixture.

That makes sense. Altho i think our engine also has a MAP sensor and i'm fairly sure there are turbo setup tuned with the MAF only on the boost side of the turbo.

I did a search and you're right, it does have a MAP sensor so it shouldn't be a problem.

I ordered one. I don't expect to gain power with it. But I don't see it hurting either. I just got it to hopefully make the Innovate SC whine louder. :D

You wont see any gains on the dyno if its like other intake ducts for cars like the s2000. The s2000 spoon duct doesnt get gains at all on a dyno since you cant imitate 60-80 mph driving on a dyno with a fan.

Who knows though maybe this will get some gains on the dyno but these types of mods work best when you are driving in real world conditions. People with the spoon mod on s2k's all report feeling a difference when you start to get to 50-60 mph.

This would be a good addition to the TRD intake

Anyone who says this isn't worth $50 is a fool! How much is it?
