The intake went on in about 45 minutes. There does seem to be a noticable hp gain. It will take some getting used to the new resonance under full thottle. This intake is LOUD.

 

Hey! There is a post above with my name on it that I didn't send.

That's the first time its ever happened to me.

Anyone know how that works?

:p

 

You can find a dyno in your area here: http://www.dynojet.com/ldynocntr.shtml . Cost will be anywhere from $60-$80 per hour. Be sure you get the shop to agree to unlimited runs within each hour, and that they do air/fuel datalogging.

I know all this because I got the Rotary Extreme CAI on my '8 (which is like the K&N only with heat shielding), and plan to get it dynoed versus stock. Results to follow within a few weeks... look for a new thread from me on it.

Hope this helps.

 

Rotor-rev, don't expect to be in the DFW neighbourhood this week.

 

WELP, IT AINT NO EXAUST KIT BUT IT DOES MAKE A DIFFERENCE. THE NOISE IS SIGNIFIGANTLY DIFFERENT, MUCH THROATIER. SOUNDS NORMAL AT IDLE AND AT CRUISING SPEED OTHER THAT THE SUCKING NOISE THAT SOUNDS LIKE A JET ENGINE AT IDLE. WHILE ITS NOT CAI, AND IN TRAFFIC IT MAY NOT BE OF MUCH BENEFIT(WHO CARES ANYWAZE, NO ONES GOIN ANYWHERE), PLENTY OF FRESH AIR ONCE YOU GET GOIN.

 

this kit goes for 189.00 not too bad i guess

 

ok this damn name thing is getting stupid jhouse posted this message and the one above

 

you can get the K&N intake on e-bay right now for $205 as well as color choice. Just type in Mazda RX-8 in the search.

 

Or from SUMMIT Racing for $173.:D

 

or truckperformance.com for 189

 

aI can't find it on summit racing man?

 

I found the instalation pdf while looking on the K&N website.
Instal guide
Has anyone installed it? Is it difficult? Reactions?

 

desmo,
good find thanks

 

You can't look it up by vehicle. You need to type in the part # listed at the beginning of this thread with KNN preceeding it. Or just call.

 

Alright folks - Both are finally available and both look great. They both seem to produce additional hp. and torque.

Which do we go with and why?

I'm under the impression that CAI (Cold Air Intake) is the better way to go but would appreciate some advice. I had a K&N on my last ride and it worked fine but the RX-8 is a totally different animal. I would plan to add the Borla or B&B Exhaust from VividRacing to round out the mods.

I've seen the K&N for $176 at Summitt Racing (search for thread)
and the RotaryExtreme CAI is $260 or a group buy of $230 (which expires 12/31/03)

Thanks in advance.

 

I didn't get any intake yet, but I would vote for RE intake. We all know that's a lot of heat under the hood. Sucking hot air into the engine doesn't seem to help the performance.

 

RE Smaller Filter though I dont know ?

 

The two intakes are almost identical. The K&N has a larger filter and the RE comes with a heat shield. The K&N is going to suck in hot air in stop and go traffic but in a full throttle run there will be the same cool air blowing in there that the RE intake would suck in. If they were both the same price I might lean toward the RE but for the difference in $ I've got a K&N on the way.

 

is the RE avaiable yet
and how much is it ?

 

Mikeb - If you check out the RE link it will answer all your questions. $260 (plus S&H) via Paypal and its available. Any thoughts on either?

 

do you have a link?

sorry
I thought you meant RE the company in japan

 

haha, so did i...RE-Amemiya...

 

IMHO Both are nice, but... Not worth the money. The stock box is as close to a cold air intake as can be. I'd rather wait for the K&N drop-in which will probably go for around $45 and, I'd wager, give you within 1HP of these two intakes.
