Has anyone deleted the resonator in the stock airbox? or made a larger snorkel?

How much louder than stock is it without the resonators?

Not much louder, mostly just a bit more induction noise at wide open throttle.

The 1 ⅞" plug.

Yeah, I remember that too.
They were also moaning about it cutting off 1/3 of the cooling air as well.

So not as loud as an AM intake or CAI would be?

I used one of these for the noise generator.

Correct.

$12 worth of parts from Advance




....Then I got a true CAI and it is sooooo much better

That's cool! I'm going to fuse plastic to delete the resonators n what not though with a hot glue gun. Or i'm going to use high temp epoxy. Haven't decided yet. I'll use chunks of the resonator to plug the holes.

As for snorkel I think for now i'm going to keep the stock. Be interesting how this sounds once done with the Perrin silicone tube. Hope it brings something to the table! if not hell yea for weight reduction and cleaned up engine bay!!! teehee.

I'm wondering if a slit in the bottom of the stock snorkel to allow for more air flow would increase power, or just ripping out the snorkel and putting the largest piece of PVC pipe you can squeeze in there?

Apologies if this is a stupid assertion, I suppose if I go ahead and try something and ruin it I have an excuse to get a perrin CAI right?!?

That sounds a good idea but I would make it a series of slots to maintain the structural integrity of the tube. It's mounted in an area of cool high pressure air and above the cooling air flow to the heat exchangers, so what could be better?

What do you mean? 1/3 of the cooling air...?

How are you liking that intake duct? I was thinking of getting one since I really LOVE the syms racing intake duct and the other one that is similar to Syms. A good drop in filter/ Silicone tube from Perrin would all benefit each other nicely and probably out perform any intake on the market. A drop in already does better than most intakes on the market so imagine with a drop in, silicone tube and that intake duct. Syms Racing has a vendor dyno of about 10 whp and Gruppe M has said there dual intake duct got about 10-12 whp so I wouldnt be surprised if this one performed close to how the Syms Racing intake duct did.

But out of the 3 this is the cheapest one. People who think that the max racing duct doesnt do anything have no idea how many other cars have similar ducts that attatch to the stock airboxes like the s2000 and work very well.

Having a duct like that isnt a problem if you live in southern california where it rarely rains. People who are worried about water getting sucked up need to use there head. No one with a brain would drive over a huge puddle. And I am sure a filter would block any little bits of water that does get sucked up when its raining hard.

It covers about 1/3 of the cooling airflow to the heat exchangers in this pic.

You do know Gruppe M sells a 2300 dollar intake that has 2 ducts like this covering the radiator. You think a company that is known for creating the best intakes on the market for this scene didnt think about that?

I am sure they did there R & D on it also and if it did affect it that much they wouldnt of used that design. So I highly doubt a duct like this will affect anything if Gruppe M's has TWO smaller ducts that cover around the same amount of area. Either way itll get air when your driving and it will still get to the radiator. Not all the air will be going through the ducts. When you driving on free way or anywhere air will find its way to the appropriate areas.


Theres already pieces of the car covering the radiator I highly doubt coverng a little more would make that big of a difference. Unless if you have data confirming that it will affect things in a major way stop it with the bro science. Look in the link below for bigger pictures.

Also Prova has a similar intake duct to Syms which is a little different in design. Syms looks like it would catch more air though. Wish they would post some info on the gains.

I really don't give a toss what you think.
It covers and blocks the flow to a large part of the heat exchangers and would certainly void the warranty in any claim involving overheating.
It's badly engineered and will likely cause problems.
There's no way I would fit it on my 86 in Australia.
