No Intake
I just got back from the dealer and they handed me this article from a M-tips brocehure.
The rx8 airbox and intake system is specifically designed to eliminate restriction and create a smooth airflow over the MAF. If a customer has installed an aftermarket air filter or intake system, the airflow stream to the MAF element may be disrupted and cause an improper MAF signal. An erratic signal may result in a rough idle condition. Also, some aftermarket air filter elements are coated in oil to improve air filtering. The oil coating may damage the MAF resulting in a poor idle or MIL illumination related to the MAF. If a customer complains of a rough idle, inspect the car for an aftermarket air filter or intake system and replace with factory componets.
what do you guys think?

This may be correct but I would like to hear from people who have done both the exhaust and the intake. Also if you are careful and don't over oil the filter it should be fine.

Well Mike if you are that worried, I can modify the K&N intake pipe to the Stock Cone and box.......or something?
Maybe that will help with the ruff idle and still give it a deep sound
When do you want to do this?

Some companies said RX-8 is going to be a favorite on the Mod list... Also it was the most MOd friendly.. i quess they were talking out of there as$... cause i thought the rx-8 would be restricted from power.. with simple bolt on i thought it would increase alot of power...

Not to trash the K&N intake, but this problem seems to be prevalent with this filter. I haven't heard of any problems with the RE intake or AutoExe or any others on the market. Anybody with one of the others have any idling problems??

When I bought my Tundra people were putting these on their trucks and were having all sorts of problems with the sensors. I think it was the MAP sensor. They had idle problems and the gas mileage went down and the performance went down. Save your money and get a proven product. I think most intakes are well designed for every day driving. If it was that simple to get hugh improvements they would already done it.

I have the Rotary Extreme Intake installed, and I haven't noticed any rough idling, except in the morning when I first start the car, the first 30 sec of idling seems a bit eratic. The engine idles around 2K - 2 1/2K for 30 sec, But afterwards the idle drops down to normal (1K) when the car is somewhat warm, everything seems fine. And throughout the day, everything is fine as well - no rough idling. As far as losing HP (according to the tech), I haven't dyno the car so I wouldn't know, but if it does (which I don't think so), prolly a few?

Not to question anyone's installation, but did you disconnect the battery before installation? The ECU then resets itself to the new intake/airflow. Might cure the rough idle for some?
BTW, mikeb I wouldn't worry about the K&N "damaging" your 8. I would agree, though, that it *might* be robbing HP (low end rpm) with it.

mikeb...
well if I was Mazda, I'd put out a general warning about all intakes. That's really the safest route. To specify one, means to test them all and then name which are ok and which are bad... which then means you are supporting one aftermarket product or another. So as you can see... a blanket statement just works better.
SO. This means our homework is to figure out if it is only K&N...which there have been some complaints on the forum about, OR if this really does apply to them all. I'd like to think that with everything that Greddy makes that theirs is ok and as far as AutoExe goes... Mazda dealerships (which are maker owned in Japan) sell and install their products. So I'd like to think they also know what they are doing as well.

The exhaust is also not that restrictive to begin with so gains will be few there as well. There are a few cars out there that get good gains from an aftermarket exhaust but this is because the worthless pile of pipes connected to their engines from the factory sucks really bad. This is bad engineering so why does the manufacturer always get crdit for a good car? This confuses me. When someone designs an exhaust system that can compensate for the damn siamesed center port, we'll see some fantastic gains. This was one of the Renesis design lowpoints and the engine still makes tons more power than the older rotaries.
A simple ecu retuning (bolt on) will yield upwards of 20+ hp. Bolt on's can do good. Why do people always buy a vehicle because it has aftermarket potential? A Civic has tons of aftermarket products but not much potential compared to other cars. That is a losing proposition to me. The RX-8 is also so new that there hasn't been enough time to get all of the mods to market yet let alone develop them properly. Anyone can make a new exhaust or cone filter system. Not everyone can develop a product that works very well.

I went to my mechanic and asked him questions about tuning the 8. He said that he had heard that the 8 was bad out of the box. The price for the punch of alot of mods are just that Pricey. And the performance gaines not worth the price. plus you could only take advantage of the mods on a track (Mainly suspension). The only viable mod would be an ECU mod. I am not trashing anyone that wants to mod, because I am right there salivating at all of it, but this just goes to show what a complete car we have purchased. The stock 8 rocks.
