opus said:I have tried the K&N website, and they only show the typhoon cold air intake system for the Mazda5. I think it is funny on the Fram sight that when you search under air filters, it does not show any match, but when you look under general search it shows an air filter match. Might just take the factory filter up to Autozone and see if it matches the design and dimensions of the K&N that they have. Should make for an interesting project.
Yeah, no need to do that. Two people have already told you it's the same filter. You can verify on www.autozone.com if you want.WhitewaterPearl said:No need to do that. P/N: 33-2293 is the correct filter.

If so, is it really noticeable? And is that the high performance model?

It goes over cloth vs paper elements and allows you to make an informed decision.

I don't agree with this. While at first you'll be running slightly lean, it's my understanding that a car's engine will eventually "learn" the new air/fuel mixture and compensate back to spec by pumping in more gas, otherwise the engine would always be burning slightly lean... possibly causing damage over time. Therefore, anything that increases airflow should drop fuel economy. If I'm wrong with that reasoning, somebody please correct me.martman said:I did find though (as well as other folks' observations) that the increased air being let into the engine results in better gas mileage...
...IMO, investing in a CAI might give you more performance for the buck. It will be a more involved install process, but the gains (more power and better fuel economy) may be worth it for you.

I suggest too not to go with a SR as SR will only suck air from an already warm/hot engine bay which defeats the purpose of having a high performance filter in the first place.

This was kind of my point. Even if you're some how taking in more air, the computer will compensate and start sucking more gas, too... consequently, in theory reducing the gas mileage.MD5 said:Back to the lean statement. Your computer reads the incoming air and compensates for it. Period. The computer doesn't know where the air is coming from, nor does it care. It reads the stats and adjusts for it.
MD5 said:A CAI won't make your car run lean. CAIs do make your car run worse, because it is taking in under hood air which is significantly higher than outside ambient air. It might take in MORE air, but it is HOTTER air. Why don't manufacturers make cars with CAI? This is why. The factory system takes in air that is NOT from under the hood.
