Nothing against K&N but the air filter they made for the Tundra cause all sorts of problems no perfromance improvements. The trouble with all these products is they off set the balance of the computer system. Believe me, I have driven and have tried to improve on the performance of cars since the 70's when the pollution controls took effect. You can't just add a component and get the effect. You have to adjust the whole system. If they could get 5 hp out of a air filter the would do it.

That's not true at all. I've tried stuff at the track and decreased my times without touching my ECU (not in my z though). Altering parameters of the ECU arent necessary to see the benefits of bolt ons. You don't need ECU flashing/tuning until major changes have been had (forced induction, cams etc..).

If you did intake, exhaust and headers on your car right now...I gurantee it would reduce your time. Fine tuning with an safc or ecu flash will help, but only by a few ponies

Sure, maybe if your new intake sucks! However, despite the alleged issues with K&N (for example) people have been using them with great success for years and years and years, in many different applications. If poor filtration were the cause of engine death, it would be pretty easy to tell from an engine tear-down. I believe the point of the Magnuson-Moss law is that the onus is on them to prove it, and if they do...sure, you'll have to foot the bill.

My experience with K&N filter has been positive. I don't see know the computer would "know" what kind of filter you're using. The claimed advantage of the filter is less resistance to airflow. From the ECU's perspective, how could it know that the increased airflow was from a better filter or something like lower altitude? I doubt the amount of improvement would take aiflow out of bounds of the map. - note this assumes a direct replacement filter and not something that requires different plumbing .

As far as performance, I really couldn't tell the difference but if somebody says 5hp on a dyno that's fine. It certainly did not degrade. My goal in buying the filter was for the longevity and re-useability factor. I've used the filter for most of the 150K on my current vehicle.

well said. Do they make stainless steel drop ins for 8s? Those are the best IMHO. Simply clean them with an air compressor

This seems to be getting more and more common. Every time I hear of someone with a CAI on their WRX I just want to smack em. It's not a good mod for all cars, just those that happen to have a poor stock intake design. Funny thing is the most common places you hear about intakes on WRXs is kill forums where people are making up BS stories about the modded car they just beat.

Don't mess around with the RX8 if you plan to keep it a few years. I would just do a K&N drop-in OEM filter when it is available. Someone may as well wait for the Mazdaspeed version if they want more power. However, gotta watch the paddle as the radars zoom in on all Rx8s.

:D

The stock intake may indeed be very good, but they still had design constraints that won't necessarily apply to an aftermarket intake. Noise, for example. That intake sound that some people like would never fly on a stock car. If, as a designer, you don't care about that, then you may be able to do things a bit differently and end up with a little better flow. Maybe. The Rotary Extreme intake dynos would seem to indicate that it is possible.

Lightbulb air filters

With the wrx, basically what I have heard with air filters is that they make your car run lean, producing more power, then when you tune the computer to run safe a/f mixtures, you lose that power, and then some, because the filter doesn't allow steady amounts of airflow into the engine.

or something like that.

this is according to cobb tuning, who do a bunch of suby stuff.

that's my .02

take or leave

p.s. I also read somewhere about the 8's intake being very painstakingly designed for harmonics, and adding a filter mightn't be good for it.

blah blah

Generally, if the stock intake on a particular car is well engineered, adding an aftermarket one will NOT make your car run lean. Even if it does, and then you tune for it, you're adding more fuel and air, right? Which should be contributing to a power increase. That's the whole point of a better-flowing intake, to get more air in...not to change the air/fuel ratio.

1,000 bucks for an intake with an air box?!?!?! it better add about 500ps, and the exhaust should be scattered with diamonds.

Is this is prototype or production? I can't seem to find details on their site.

Any word on dyno results?
