K&N does what every other company does (except Racing Beat) in terms of how they make their claims. They tell you how much PEAK power it gained. They will only tell you the absolute largest difference. What they don't tell you is that this is probably only at redline and that everywhere else you aren't getting squat and are possibly losing power. Quoting peak horsepower numbers are only good for 1 thing and that's selling product. They know good and well that many people assume that they get 10 more hp everywhere. Nope. Racing Beat has disclosed the average gain over a specified rpm range, the max gain, and the gain at peak power. That's the way to do it. They will admit that the K&N will get more absolute PEAK power than theirs will but theirs will make more average power. It's average power that makes you faster, not peak power. Peak power is good for dyno sheet bragging.

How long is the old K&n filter. I want to know because i will be replacing it with a S&B filter.

this was posted before where import tuner had an article with the new k&n intake, modest gains 2-3 hp average across the powerband. Think peak power was around 5hp. Thr rx8 had 187 hp, with exhaust, groundwires, and intake it put it at 194 ish.

I spoke with one of the K&N reps recently and he said that the new intakes are being prepared for shipment and should be good to go in 7-10 days. Then we can really see if they made any improvements over their current intake.

These guys must really know what they are talking about - NOT![/color]

I JUST [2:10PM EST] called them and said I saw their new intake in June R&T and the sales rep said, and I quote him "All RX-8 intakes have been discontinued." [/color][Of course I gasped a bit, and said "What?" He again repeated that and said "I actually don't know why, but they are no longer being offered!" [/color]

So I asked if they would be released in the future again, and he said he thought they might but had no idea when, just check the web site now and then.....

So I said what about the full page add in R&T? He said "Well, that one was actually released for ***about a week****, but was withdrawn."[/color]

Now given what SR heard, the truth of the matter is as confused as ever...I think... or maybe not...I'm confused??

]Look who you spoke with about the intake, a lowly Sales Rep. They are always the last to know anything. I too have contacted some folks at K&N and they back up what SR stated...

Spin9k

So call and ask for your own ears....then report back...

Sorry, at work no can do. I have been dealing with the folks from K&N's Technical Support Dept. I sure as heck trust them over a "sales rep". Do you believe everything a car salesmen tells you?

dwill9578

the revi is the way to go, why even bother with any other intake???

Speed Racer

I just checked their website and noticed that the intake is missing from there too. It wouldn't surprise me if they have discontinued their current intake as they are ramping up production of the new one.

Just because Racing Beat has a good design doesn't mean someone else can't also have one.

Spin9k

Not owning either, I remain an equal opportunity consumer....until I see back to back dyno runs on any solution I doubt all claims - regardless

There are two reasons why Manufacturers aren't making products for our cars:
#1 They all want to sleep with a 350Z or Evo
#2 They are too busy developing ricer products for Honda

Racing Beat or other "niche-focused" companies do not have #1 or #2. This is why they can spend R&D money and time to make products that really work. I don't believe K&N is serious about marketing to RX-8s at all--at least not yet. Just my thoughts.

free bump I wanna know if anyone has heard anything else

coupe07

i totally agree with u..

dun be too fast to condemn k&n new intake when no one has tried it yet..... looking at the design, i wld say its gg to be very good...

There is a full page ad in the Aug 05 Car and Driver from K&N for this new intake system. It says "10 horsepower to the rear wheels on a stock Mazda RX-8 guaranteed" and has a huge picture of the intake system.

cas2themoe

Are you serious? I will be buying that if they can Guarantee it! Any links? Woo Hooo

Red Devil

They have an add in the latest Speed Magazine also. In it they make specific mention of resonance tuning this new intake to work with the MAF. Could be promising. They seem to have made definite efforts and to have done their homework. Besides, it makes no logic to come out with another faulty product after a first failed attempt.

KYLiquid

are you sure your reading all the *------ and the fine print?

most of the K&N ads, as well as AEM and other parts makers (as well as all kinds of other companys making things) say somethings like :

"up to 10 horsepower to the rear wheels on a stock mazda rx8 guaranteed"

by simply adding 'up to' you could make zero, or 10, or lose power and they are still filling their guarante.

its the same kind of thing all the time....offers that sound good at a glance (companys hoping for the impulse shoper) usualy have something else there that makes the original promise not so great.

hell most advertising only tells you the least it has to about a product so youll hopefully buy it and find out the rest after youve spent your money......but i am ESPECIALY cautious when the ad has crazy fonts, lots of images making the text hard to read, heavy use of muli-color letters and bold/italic/regular font or lots of changes in text size.

you can type the same sentence mulitple times, each timing just making some words bigger or smaller, chaning the font, making it bold or making the color different, and after reading it you have a different idea from it.


the time were living in now....with lawyers writing everything.....you really cant belive that a specific product with do xxxxx for you.....all you can do is buy the products from a company that you trust, or has a good track record and hope for the best.

as i write this, the K&N banner ad is at the top of the page.

1st sentence : " K&N Air Intakes Increase Power!"
2nd sentence : "GUARANTEED!"
3rd sentence : "9.5HP Increase on RX-8!"

what I take away from reading this :

there are 3 sentences, while they seem to be linked...they could infact be 3 totaly different thoughts. the 1st sentence is telling tell you that their intakes increase power, all of them? just one of them? what one specificaly? the rx8 intake? also, power...as in horsepower, torque....power can mean different things. 2nd sentence is just the word garanteed.....what is garanteed? 3rd sentence 9.5hp increase, where, topend, overall, at the wheels, at the crank? what year car? what engine flash? is this over stock, or over a different intake, were there other mods?

just trying to show you, nothing is as simple as it appears at first glance...

You are such a lawyer! :D If they would provide dynos of this then I would consider it. However, I wonder what the noise difference is between the RB and the KN. I am assuming the RB is quieter.

bureau13

They had supposed dynos of the first version of their intake. It will take more than posting a chart. That said, I tend to believe K&N makes pretty good products, I think they just got a little to complacent with their first intake for the 8. The fact that they bothered to do some analysis and come out with a better product tells me they're serious about getting it right. Face it, the vast majority of people buying these cars are not reading this or any forum. K&N could have continued to sell the old intakes to people who didn't know anything but the name brand...they didn't do that, so more power to them.

I'm quite pleased with my REVi, but the more quality products out there for the car the better I like it.

Bah, dynos won't prove anything. Do a baseline at 109F, 95% humidity, with the car pulling timing for hot coolant. Then do the proof at 65F 15% humidity. Hmm, look at that, 10 HP gain. Don't believe the hype. Independent (not magazine) verification of before and after is what you should want. For any product.

WoodyCH47

Well first of all I'm so very glad I checked this forum first...........I signed up a while ago but haven't really been on in a while (job keeping me busy). I was about to go buy the K&N Typhoon #69-6030(not sure if this is the latest one). But now I'm waiting for someone who is going to dyno and post specs before I buy. I also like to say that this forum does exactly what it is supposed to: provides a place where people can share their ideas, experiences, and opinions which allows other people to benefit I am more of your typical guy, not your die hard tuner, I just want to spend a small amount of cash and get the most out of it. Also I would be greatful if, when people refer to other systems to provide a link..........
