As you know there are 2 intake availible k&n and Rotaryextreme intake. Which one should i get? I want the Rotaryextreme but price is alittle to high for me but comes with a heat sheild. I want the typhoon cuz it looks better but doesnt come with the heatsheild but is well in my price range. I read that K&N will have a heat sheild soon anyone know how much it will run for, so then at the end which intake is cheaper. Is the typhoon worth getting w/o heatsheild and for their heatsheild o come out

p.s if i am persuaded towards the k&n wheres is the CHEAPEST website i can get it and if i am persuaded towards the Rotaryextreme is that only website i can get it at?

i want intake b/c its the cheapest engine mod i can afford

 

What do you want from the mod?

If you're looking for a noticeable performance increase - an intake won't do it. Even if it gives 5 hp at peak 8500 rpm (which is about all the best of them claim), that is very hard to detect without timing equipment - ie you won't notice it. Worst case, there are quite a few knowledgeable people on the forum who state that the factory intake is extremely well designed and that there's no power benefit to be obtained from replacing the intake.

If you're looking for a louder intake noise - then they definitely deliver that!

my opinion from experience, do not go with an aftermarket intake, the stock one is fine. It will soind good up to 6500rpm, then you will hear the dreaded broken up air sound wich is the additional flaps oprning up, the stock set up muffles this so you can not hear it, also you will lose some low end power, and just imagine when it is humid outside.

 

Exactly what I was thinking.

 

I would wait for APEXi to come out with an intake. As many know, the K&N filter's oil can cause problems with the MAF. The APEXi filter is not only a dry filter without any type of oil, it also filters better from the independent test I have seen.

 

Dookie - there is a thread already out which goes over the whole comparison b/w the two. I initially started the thread but it somehow turned into a poll thread. Try a search and that should help you decide further which direction to go.

My advice is not to get a mod just to get a mod. The intakes aren't really proven to make that much difference other than noise thusfar. Maybe save the money until you have enough for an exhaust, ECU mod or until there are more intakes to choose from and there is data to back them up.

Yes, I know that K&N is reporting 10hp, or something of the like, but nobody that has had one installed has had the opportunity to back their statements up. Just my $.02. Which ever you choose to go with, best of luck. You'll be happy either way.

 

One more vote for passing on both units.

K&N is a household name

can't go wrong with it

I love mine just waiting for the heat shield

 

i dont really care about proformance as long as its not taking way horespower ,i want sound thats what i want

 

Then hook it up, Dook! You can get the K&N for $199 on EBay! Sold! Get us a sound clip and some pics while your at it.

 

Decide what you want to hear - The air intake or the Rotary whine. I'll take the whine, plus I've yet to see an aftermarket intake from anybody that actually produced anything other than noise.

 

And my signature below says it pretty well, too.

 

well always can take it off right?

 

is this is why a sound clip would help me decide faster or slower

would i still lose low end power if i had the heild shield?

 

Take your time and wait. I would..it will be worth it in the end. Perhaps when some performance mags decide to start reviewing intakes, make a decision then. It depends on what you want, how much you value the life of your engine, and well money!

 

R-E intake and several exhaust clips at https://www.rx8club.com/showthread.p...&highlight=mp4

 

wait your saying intake cuts the life of the engine

 

you can get the k&n intake from summit racing via summitracing.com (you will have to call them to order it tho its not on their website) and its only $176.39 before shipping and it take about a wekk because its so new they dont have them in stock but will save you some money!

 

Guys,

I own a Rotaryextreme intake and it is in deed amazing. The sole fact that it has a "complete" heat shield puts it above the K/N. Also, you can definitely feel a performance gain & the sound it makes at high RPM is great.

The movie clip that "Genom" posted above is of my Rotaryextreme intake. Check it out......Thanks for the file Genom....

 

Perhaps you can, but absolutely NOBODY besides Rotary Extreme has done back to back dyno runs to compare the stock intake to their RE intake - there is zero independent hard data to confirm any power increase. All anybody who's bought has said is "it sounds great" - why hasn't anybody actually tested it?????

I've never heard this before. Got a source? I've used K&Ns for years on my FD but of course I don't have a MAF :-)

Can a heat sheild really help that much. To me I would think that it would restrict HP b/c it is restricting air flow around the filter. And when the car is in motion, would there even be hot air in the front of the engine bay?

 

And that is precisely the problem... when the car is NOT moving... i.e. stop and go traffic. It has been reported that there was a noticable power loss in hot stop and go traffic. Thus all the talk about needing the heat shield... As far as resticting hp goes... the stock box isn't that bad at all... thus I doubt it has much effect in that way...

 

I would like to clarify a comment or two about what I posted above about the my above comments re the CAI intake .

Apparently the length of the MAF pipe is quite critical to the power produced. The intake I saw had been shortened. I am not sure why it was shortened, but it was apparently to get it to fit. It appears this was a mistake.

My comments about performance with the stopwatch should be disregarded, as the component under test was not within it's intended specification.

Public appologies if this appeared to be a sabotage. It is right for us to give public opinons on this place, but it not right is the facts are skewed.

But I did say the quality of the manufacturing was first rate!

My only concern (still) is I would seal around the edge of the heat sheild with some thick foam tape to help prevent hot engine air getting in. Chuck says some of the additional air gets in through the small gap, so maybe it is not a great idea. I just don't like hot air going into my motor!

I would like to be able to do back to back tests with my MR Dyno, but unfortunatley my buddy lives in another city 9hrs drive away.

Cheers,
Hymee.
